Lecture 5
The document discusses the hydrologic cycle and water on Earth. It describes how water moves between various reservoirs in the cycle, driven by energy from the sun. The largest reservoirs are the oceans, polar ice sheets, and groundwater. Streams and drainage systems transport water across land surfaces and influence landscapes. Groundwater flows underground through porous rock and may discharge into springs, lakes, or streams. Water is essential for human and ecosystem needs but is increasingly threatened by pollution, overuse, and other impacts of human activities.
The hydrological cycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from oceans, lakes, and vegetation and rises into the atmosphere. It condenses to form clouds and precipitates as rain or snow. Precipitation that falls on land either infiltrates soil and recharges groundwater, flows overland as surface runoff returning to oceans, or is intercepted by plants. Ice also plays a role, storing water as snow and glaciers that slowly melt. The cycle continually repeats as water is recycled and redistributed around the globe.
Hydrological cycle
This presentation is describing about the water cycle. It explain about how water transfer in atmosphere, lithosphere, hydrosphere and biosphere.
Hydrologic cycle
The hydrologic cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water is evaporated from bodies of water by the sun's energy, rises into the atmosphere as water vapor, condenses to form clouds, and falls back to the Earth's surface as precipitation onto land and oceans, where some is absorbed by plants and soil, some runs off into streams, rivers, lakes, and oceans, and some infiltrates and replenishes groundwater stores. This constant movement of water driven by energy from the sun is known as the water or hydrologic cycle and is essential to supporting life on Earth.
Hydrological cycle
Hydrological cycle also called water cycle is the earth's water circulatory system. Hydrologic cycle is a continuous process. The total water supply of the earth, except the deep ground water is in constant circulation from earth to the atmosphere and back to the earth.
Hydrologic cycle and field water balance
The document discusses the hydrologic cycle and field water balance. It provides details on:
1) The hydrologic cycle, which describes the circulation of water between the atmosphere, land, oceans and biosphere through processes like evaporation, condensation, precipitation, and runoff.
2) Components of the hydrologic cycle like green water, blue water, infiltration, recharge, and groundwater flow.
3) The field water balance accounts for all water inputs, outputs, and storage within a soil area over a period of time based on the law of conservation of mass. It considers precipitation, runoff, evapotranspiration, and changes in water storage.
The hydrologic cycle and water resource of world
The hydrologic cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water is evaporated from oceans and land surfaces, rises into the atmosphere, cools and condenses to form clouds, and falls again as precipitation. Some precipitation runs off surfaces and becomes surface water in oceans, seas, rivers, lakes, and groundwater; other precipitation is intercepted by trees and vegetation; and some infiltrates and recharges groundwater stores. Water is also transpired into the atmosphere from plants and other surfaces. The hydrologic cycle involves the balanced circulation of water in the hydrosphere, atmosphere, geosphere, and biosphere.

Hydrological Cycle (Water Cycle)
The hydrological cycle is the system which describes the distribution and movement of water between the earth and its atmosphere. The model involves the continual circulation of water between the oceans, the atmosphere, vegetation and land.
hydrological cycle/ water cycle
This document presents information about the hydrological cycle presented by Rahul Kumar Lilhare at the College of Agricultural Engineering in Jabalpur. It describes the major components and processes of the hydrological cycle, including evaporation, transpiration, condensation, precipitation, interception, infiltration, runoff, and groundwater flow. It notes that the cycle involves the storage and movement of water between the biosphere, atmosphere, lithosphere, and hydrosphere. The global cycle is divided into the atmospheric, surface, and subsurface water systems.
Water cycle
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the Earth's surface. It involves several processes such as precipitation, runoff, infiltration, subsurface flow, evaporation, condensation, and transpiration. These processes work together to circulate water in a cycle, driven by energy from the sun. Without the water cycle, which regulates the planet's temperature through evaporative cooling of the oceans, Earth might have a warmer climate.
Hydrological cycle and its components
The document discusses the hydrological cycle and its components. The hydrological cycle describes the storage and movement of water between the biosphere, atmosphere, lithosphere, and hydrosphere. Water evaporates from oceans and transpiration from plants, condenses to form clouds, and precipitates as rain or snow. Precipitation runs off and infiltrates the ground, becoming groundwater that eventually discharges into water bodies, completing the cycle as water evaporates again from oceans. The main components are evaporation, transpiration, condensation, precipitation, runoff, infiltration, and groundwater flow.
Hydrological cycle
The hydrological cycle involves the continuous circulation of water on Earth. Water evaporates from surfaces, is carried by winds, condenses into rain or snow clouds, and precipitates back to the ground as rain, snow, or hail. This water may be stored temporarily in oceans, soil, groundwater, and glaciers before returning to the atmosphere through evaporation and transpiration from plants. The sun provides the main source of energy driving the hydrological cycle through evaporation of water from land and sea.

The document discusses the hydrological cycle, which is the continuous movement of water on, above, and below the surface of the Earth. It is driven by energy from the sun and involves evaporation of water from oceans, lakes, and soil into the atmosphere; condensation of water vapor into clouds; and precipitation of water back to the Earth's surface as rain, snow, or hail. This cycle is crucial for sustaining life as it regulates and redistributes fresh water on Earth.
Water cycle
Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet.
The hydrological-cycle
The hydrological cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water is evaporated from bodies of water by solar energy, transpired from plants, and condensed into clouds. Clouds are moved by wind and precipitation falls as rain or snow and returns to bodies of water, either above or below ground. This cycle maintains a balance, but human activities like deforestation, agriculture, and industry can disrupt it and cause impacts like increased flooding and soil erosion.

The document discusses the hydrological cycle, which is the continuous movement of water on, above, and below the Earth's surface, powered by energy from the sun. It describes the main stages as evaporation, transpiration, condensation, precipitation, infiltration, and runoff. It also addresses human impacts such as pollution and how we withdraw water for agriculture, drinking, and industry.
Hydrological cycle
This document summarizes key aspects of the hydrological cycle and atmospheric processes. It describes the layers of the atmosphere, global wind belts formed by uneven heating and the Earth's rotation, cloud formation, types of precipitation including rain, snow, hail and their measurement. The hydrological cycle involves evaporation and transpiration of water from surfaces, condensation of water vapor to form clouds, and precipitation of water in different forms which completes the cycle.
Hydrologic cycle
The hydrologic cycle describes the constant circulation of water on Earth. Water evaporates from the oceans and atmosphere due to solar radiation. It exists as water vapor in the atmosphere and condenses to form clouds and precipitation. Precipitation falls back to Earth as rain, snow, or hail. Some precipitation is intercepted by vegetation or structures, where it either evaporates back into the atmosphere or flows across and through the ground as surface water or groundwater. Runoff water flows through streams and rivers back to the oceans, completing the cycle.
Hydrologic Cycle
Water is essential for life and the hydrologic cycle distributes it around the planet. The cycle involves evaporation, transpiration, condensation, precipitation, collection as runoff or infiltration into groundwater, and storage in oceans, glaciers, and ice caps. Climate is influenced by the hydrologic cycle as warm air holds more water vapor and rising air cools, causing precipitation. Changes to the cycle, such as intensification due to climate change, can produce more extreme flooding and drought.
Explanation watercycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water into the air due to heat from the sun, condenses to form clouds, and falls back to Earth as precipitation. This cycle is crucial as it provides fresh water for living organisms and sustains life on the planet.
The Water cycle Presentation
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. It is driven by energy from the sun and involves the processes of evaporation, transpiration, condensation, precipitation, and runoff. Water is evaporated from bodies of water by the sun, rises into the atmosphere as water vapor, cools and condenses to form clouds, and falls back to the Earth's surface as precipitation from where it collects in rivers and streams or soaks into the ground to replenish groundwater before returning to the oceans, closing the cycle. The water cycle is crucial to sustaining life on Earth.
Nitrogen cycle PERIOD 5
The nitrogen cycle describes the movement of nitrogen through the environment. It involves nitrogen fixation by bacteria, ammonification by decomposers, nitrification by soil bacteria, and denitrification by bacteria in waterlogged soils that converts nitrogen back to its gaseous form. Human activities such as fossil fuel combustion, use of nitrogen fertilizers, and livestock ranching have significantly increased the global nitrogen cycle, causing issues like smog, acid rain, eutrophication, and increased greenhouse gas emissions. While some seek solutions, many nations prioritize food production over environmental impacts.

Nutrient Cycling
I apologize, upon reviewing the document I do not see any clear questions or statements that can be summarized in 3 sentences or less. The document appears to be providing information about various nutrient cycles but does not contain a conclusion or main point that can be briefly summarized.
Nitrogen cycle - Honors only 2.04
The nitrogen cycle describes how nitrogen is converted between its various forms as it circulates in the biosphere and lithosphere. Atmospheric nitrogen is converted to ammonia or nitrates through nitrogen fixation, which occurs via lightning, industrial fixation, or biological fixation by bacteria. Ammonia is converted to nitrites and nitrates through nitrification by nitrifying bacteria. Organic nitrogen from dead organisms is broken down into ammonium through ammonification by bacteria. Nitrates are converted back to atmospheric nitrogen through denitrification, replenishing the nitrogen in the air.
N2 fixation sith
Nitrogen is essential for all life and is required to make proteins, DNA, RNA and other biomolecules. It can be obtained through nitrogen fixation, the process by which atmospheric nitrogen is converted to nitrogen-containing compounds that can be used by plants and other organisms. This process is carried out by bacteria that are able to break the strong triple bond of dinitrogen gas and "fix" it into useable forms like ammonia. Important nitrogen-fixing bacteria include Rhizobium species that form symbiotic root nodules on legumes and blue-green algae. Nitrogen fixation provides the main natural source of nitrogen in ecosystems and is vital for agriculture.
Nitrogen cycle
The document discusses the nitrogen cycle. It describes how nitrogen exists in the atmosphere but is converted by bacteria and algae into forms that can be used by plants and animals through biological fixation. Lightning and industrial processes also fix nitrogen. Plants take up nitrogen from the soil and animals get nitrogen from eating plants. Nitrogen is returned to the soil through animal waste or decay. Bacteria then convert nitrogen back into forms that can re-enter the atmosphere, completing the cycle. The nitrogen cycle is essential for providing the nutrient needs of all living things.
Nitrogen Cycle
1. Nitrogen-fixing bacteria convert nitrogen gas from the air into nitrates that can be used by plants and animals.
2. Plants take up nitrates and use them to produce proteins. Animals obtain protein by eating plants or other animals.
3. After death or waste excretion, decomposer bacteria break down organic matter into nitrates, completing the cycle.
CARBON CYCLE (teach)
Carbon cycle slide show to be used to teach the carbon cycle to students. Probably appropriate for 5th or 6th grade students.
Nitrogen cycle
The nitrogen cycle is a natural process in which atmospheric nitrogen enters the soil and becomes part of living organisms. It is essential to living things and plays an important role in ecosystems. The steps of the nitrogen cycle are nitrogen fixation, nitrogen assimilation, ammonification, nitrification, and denitrification. Human activities like cultivation, harvesting, and fossil fuel use can disrupt the nitrogen cycle and cause over-supply of nitrogen in the environment, leading to issues like soil acidification and increased greenhouse gases.
Nitrogen Cycle Powerpoint
The document summarizes the nitrogen cycle, which is a process by which nitrogen is converted between its various chemical forms and circulated among air, land, water, and living organisms. Nitrogen is essential for all life and comprises 70-71% of the atmosphere. It enters organisms through eating, drinking, and breathing and is converted to forms such as ammonium, nitrates, and urea that can be used by plants and animals. The nitrogen cycle is linked to the water cycle as nitrogen is absorbed by plants from the soil and returns to the atmosphere.
Carbon and nitrogen cycle
The document discusses the carbon and nitrogen cycles. It describes how carbon and nitrogen move between different reservoirs on Earth, including the atmosphere, living organisms, oceans, and fossil fuels. Key steps in the carbon cycle include photosynthesis, respiration, decomposition, and the burning of fossil fuels. The nitrogen cycle involves nitrogen fixation, decay, nitrification, and denitrification as microbes convert nitrogen between gas, organic, and inorganic forms. Human activities like burning fossil fuels are increasing carbon dioxide levels and affecting global climate.

Water cycle.pdf
The water cycle describes the continuous movement of water on, in, and above the Earth. Energy from the sun drives the water cycle by evaporating water from oceans, lakes, and vegetation into water vapor in the air through evaporation and transpiration. Water vapor condenses into clouds and precipitation falls to the ground as rain or snow through condensation. Water re-enters oceans and lakes through surface runoff and underground streams, where it will again evaporate and continue the cycle. The water cycle is essential for life on Earth and influences climate and weather patterns.
Water cycle
The water cycle describes the continuous movement of water on, above, and below the Earth's surface. Water exists as a liquid, vapor, and solid states as it moves through the water cycle, which includes processes like evaporation, condensation, precipitation, and runoff. The sun drives evaporation of water from sources like oceans, lakes, and soil into water vapor in the atmosphere, which then condenses to form precipitation like rain, snow, hail, or fog that falls back to the Earth's surface, completing the cycle.
Water cycle - class 8. Pptx ( Monalisa )
The document discusses the water cycle, which is the continuous movement of water on, above, and below the surface of the Earth. It involves processes like evaporation, transpiration, condensation, precipitation, infiltration, and surface runoff that circulate water between the oceans, atmosphere, and land. Evaporation transfers water from surfaces to the atmosphere, transpiration releases water vapor from plant leaves, condensation changes water vapor to liquid water in clouds, and precipitation deposits water in the form of rain, snow, or hail. Infiltration moves water underground and surface runoff carries water over land surfaces. The water cycle is essential for sustaining all life by recycling fresh water supplies.
WATER CYCLE
The water cycle consists of evaporation, transpiration, condensation, precipitation, and runoff. Evaporation occurs when water is heated by the sun and changes from a liquid to a gas. Transpiration is when water vapor is released from plants. Condensation happens when water vapor in the atmosphere cools and changes back to a liquid, forming clouds. Precipitation describes when this condensed water falls back to Earth as rain, snow, or hail. Runoff then transports this water across land through streams, rivers, and other pathways. Human activities like deforestation, urbanization, and agriculture can impact the water cycle by changing infiltration, runoff, and groundwater levels.
Water cycle
The water cycle describes the processes that drive the movement of water throughout the hydrosphere.
Nature recycles the earth's water supply through a process known as the water cycle or hydrologic cycle.
Hydrological cycle and its components
The document discusses the hydrological cycle and its components. The hydrological cycle describes the storage and movement of water between the biosphere, atmosphere, lithosphere, and hydrosphere. Water evaporates from oceans and transpiration from plants, condenses to form clouds, and precipitates as rain or snow. Precipitation runs off and infiltrates the ground, becoming groundwater that eventually discharges into water bodies, completing the cycle as water evaporates again from oceans. The main components are evaporation, transpiration, condensation, precipitation, runoff, infiltration, and groundwater flow.
Presentation(watercycle)
The water cycle describes the continuous movement of water on, above, and below the Earth's surface. Water evaporates from oceans, rivers, soil, and plants and becomes water vapor through heat from the Sun. Water vapor rises and condenses into clouds before falling back to Earth as precipitation in forms such as rain, snow, or hail. The water is then absorbed by soil and other surfaces and the cycle repeats.
Hydrologic cycle
Hydrologic Cycle is also called as Water Cycle. It basically deals with transformation of water in different forms starting from gaseous stage (water vapor) to liquid state (water on earth's surface), and water inside soil as underground water.and again back to gaseous stage. The cycle has no starting or end.
Water cycle
The document summarizes the water cycle through evaporation, condensation, and precipitation. It explains that water evaporates from bodies of water and becomes water vapor in the atmosphere. The water vapor then condenses to form clouds and precipitation like rain or snow. Precipitation falls back to the ground and bodies of water, completing the cycle.
Water cycle
The water cycle describes the continuous movement of water on, above, and below the Earth's surface, driven by solar energy. Water evaporates from oceans and other bodies of water, rises into the atmosphere as water vapor, cools and condenses into clouds, and falls as precipitation onto land and oceans, where some infiltrates the ground and some runs off into rivers and lakes, eventually making its way back to the oceans, to complete the cycle. The water cycle involves the exchange of energy and is essential for life on Earth.
Fresh water
The document summarizes the water cycle, which is the continuous movement of water on, above, and below the Earth's surface. The water cycle has no beginning or end as water changes between liquid, vapor, and ice forms through processes like evaporation, condensation, precipitation, surface runoff, infiltration, and transpiration. These processes work together to move water from the Earth to the atmosphere and back again in an endless, interconnected cycle.
Water cycle
The water cycle describes the continuous movement of water on, above and below the Earth's surface through various stages. Water evaporates from the land and ocean surfaces into water vapor in the air, where it condenses to form clouds and precipitates as rain or snow back to the ground. Some processes in the water cycle include evaporation, condensation, precipitation, transpiration from plants, and surface runoff of water from land into streams, rivers and lakes. The solar-powered water cycle is crucial for replenishing fresh water on Earth and regulating its temperature.
The-Water-Cycle-group4.ppt
The water cycle, also known as the hydrological cycle, describes the continuous movement of water on, above, and below the Earth's surface through evaporation, transpiration, condensation and precipitation. It involves the conversion of water between liquid, solid and gas as it circulates through the atmosphere, oceans, rivers, lakes, groundwater and land. The water cycle is crucial for maintaining the climate and providing freshwater for ecosystems to sustain life on Earth. It consists of several key processes including transpiration, evaporation, condensation, precipitation, accumulation, infiltration and percolation, and surface runoff.
Water education ppt
Hydrology is the study of water flow across and through near-surface environments. The document discusses key aspects of the hydrologic cycle including precipitation, evaporation, transpiration, runoff processes, factors affecting water movement in soils, groundwater flow, and human impacts. It provides explanations and examples of different types of precipitation, runoff, and groundwater mechanisms. Dams and their various structures are also described along with issues like leakages and safety considerations in seismic areas.
The water cycle 1
The water cycle involves six main processes: transpiration, where water moves through plants and evaporates from leaves; condensation, where water vapor in the air condenses into liquid water; precipitation, when condensed water falls to Earth as rain, snow or hail; surface runoff, excess water that flows over the land when the soil is saturated; accumulation, where surface runoff collects in bodies of water; and evaporation, the process of liquid water turning into water vapor gas.
1.1 drainage basin system
The document defines key terms and concepts related to hydrology and the hydrological cycle. It describes water as moving through various stages of storage and transport within the drainage basin system, including precipitation, interception, evaporation, infiltration, soil moisture, groundwater, transpiration, and discharge. It notes that the hydrological cycle involves the movement of water between the atmosphere, lithosphere, and biosphere.
Water cycle chris and catherine
The water cycle describes how water is constantly circulating between oceans, atmosphere, and land. It involves processes like evaporation as heat from the sun turns water into vapor, condensation as vapor cools and forms clouds, precipitation when clouds become too heavy and water falls as rain or snow, collection as precipitation is absorbed into the ground or flows into waterways, transpiration through plant leaves, and percolation as water slowly filters through soil.
HYDROLOGICAL CYCLE.pptx
The hydrological cycle involves the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from surfaces into the atmosphere, condenses to form clouds, and precipitates as rain or snow back onto the Earth's surface, where it collects in lakes, oceans, soil, and underground aquifers before returning to the atmosphere through further evaporation or transpiration from plants. The sun drives the hydrological cycle by providing the energy needed for evaporation and transpiration. This cyclic movement of water is crucial to life on Earth and is known as the hydrological cycle.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water & nitrogen cycle etc.
- 2. Water Cycle
- 3. It is also known as hydrologic cylce. describes the continuous movement of water on, above and below the surface of the Earth. The water cycle is also essential for the maintenance of most life and ecosystems on the planet.
- 6. Processes involved: • Precipitation – Condensed water vapor that falls to the Earth's surface . Most precipitation occurs as rain, but also includes snow, hail, fog drip, graupel, and sleet. • Canopy interception – The precipitation that is intercepted by plant foliage, eventually evaporates back to the atmosphere rather than falling to the ground.
- 7. • Snowmelt – The runoff produced by melting snow. • Runoff – The variety of ways by which water moves across the land. This includes both surface runoff and channel runoff. As it flows, the water may seep into the ground, evaporate into the air, become stored in lakes or reservoirs, or be extracted for agricultural or other human uses.
- 8. • Infiltration – The flow of water from the ground surface into the ground. Once infiltrated, the water becomes soil moisture or groundwater. • Subsurface flow – The flow of water underground, in the vadose zone and aquifers. Subsurface water may return to the surface (e.g. as a spring or by being pumped) or eventually seep into the oceans. Water returns to the land surface at lower elevation than where it infiltrated, under the force of gravity or gravity induced pressures.
- 9. • Evaporation – The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. The source of energy for evaporation is primarily solar radiation. Evaporation often implicitly includes transpiration from plants, though together they are specifically referred to as evapotranspiration. • Sublimation – The state change directly from solid water (snow or ice) to water vapor.
- 10. • Percolation – Water flows horizontally through the soil and rocks under the influence of gravity • Plate tectonics – Water enters the mantle via subduction of oceanic crust. Water returns to the surface via volcanism.
- 11. • Condensation – The transformation of water vapor to liquid water droplets in the air, creating clouds and fog. • Transpiration – The release of water vapor from plants and soil into the air. Water vapor is a gas that cannot be seen.
- 12. • Deposition – This refers to changing of water vapor directly to ice. • Advection -movement of water — in solid, liquid, or vapor states — through the atmosphere. Without advection, water that evaporated over the oceans could not precipitate over land.
- 13. Nitrogen Cycle
- 14. Nitrogen Cycle the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
