Seasonal variation of physicochemical parameters of water and sediments from ...
This document summarizes a study on the seasonal variation of physicochemical parameters in the water and sediments of Iko River in Nigeria. Key findings include:
- Salinity, chloride, and cation levels in the river water exceeded WHO limits, indicating saline water intrusion from the nearby Atlantic Ocean.
- Sediments were predominantly medium to fine sand, containing over 200mg/kg of total hydrocarbons.
- Pollution indices calculated for wet and dry seasons showed some pollution, particularly in the dry season due to lower dilution.
- Most parameters measured, including dissolved oxygen, were within WHO guidelines for surface waters supporting the study's aim to monitor pollution levels.
Lakes and Ocean
The document discusses different types of lakes and oceans. It describes five types of lakes: tectonic, volcanic, glacier, salty, and artificial lakes. Tectonic lakes are formed by earth's crust movement, volcanic lakes occur near volcanic activity, and glacier lakes result from glacial scouring. Salty lakes have limited freshwater supply. The document also lists three lakes in Bukidnon: Lake Napalit, Lake Pinamaloy, and Lake Apo. Oceans are defined as large bodies of salt water covering most of Earth. Ocean water movement is driven by wind and modified by coriolis effect, as well as upwelling, downwelling, and tidal forces caused by the moon and
Greater Vancouver Local Environment Geography
Greater Vancouver is a region located in southwest British Columbia that includes cities like Vancouver, Surrey, and Richmond. It has a temperate climate with warm, dry summers and mild, wet winters. The region lies within a temperate rainforest biome and Pacific Maritime ecozone. Common trees include Douglas fir, western red cedar, and western hemlock. Soils are predominantly orthic humo-ferric podzol and orthic humic gleysol. Agriculture is an important industry in the region, with over 2,800 family-run farms generating $789 million annually, though agricultural land faces development pressures.
Lakes
Lakes are inland bodies of fresh water formed in depressions on the land surface. They are found all over the world but are most common in high latitude and mountainous regions. Lakes form through processes such as glacial erosion and deposition, shifts in the Earth's crust, volcanic activity, and landslides. Lakes stratify into layers based on water temperature and density. In temperate lakes, seasonal changes cause the layers to mix, replenishing oxygen levels. Lakes support a variety of plant and animal life adapted to different depths and oxygen conditions. Human activities can negatively impact lakes through pollution, development, and other disturbances.
Fresh Water Notes (Ch 11)Andie
The document discusses the Earth's freshwater resources. It notes that only 3% of the Earth's water is freshwater, with 97% being saltwater. Of the 3% freshwater, 76% is locked up in ice sheets and glaciers, while 23% is underground. The water cycle, which is powered by the sun, moves water between bodies of water, land, living things, and the atmosphere through evaporation, condensation, and precipitation. Fresh surface water exists in rivers, lakes, and wetlands. Underground, freshwater is stored in aquifers, which are porous rock that can be accessed through wells. The document also discusses freshwater pollution and the importance of water conservation.
Lake
This document discusses stratification in lakes. It describes how lakes are vertically divided into three layers - the epilimnion on top which is mixed by wind, the metalimnion in the middle where temperature drops rapidly, and the hypolimnion on the bottom which remains cool and unaffected by wind. It also explains how the stability of this stratification depends on the energy required to uniformly mix the layers, and discusses differences between eutrophic and oligotrophic lakes in terms of biomass, diversity, and water quality.
Chapter 6.2 - Lakes and Reservoirs
The document discusses the formation and ecology of lakes. It describes how lakes form naturally from glacial scouring, sediment deposits from glaciers, and crustal movements. Lakes can also form after volcanic eruptions when rain fills the collapsed caldera. Human-made lakes occur when dams are constructed. The document then covers the different life found in shallow and deep zones of lakes, how sediment and nutrients affect lakes over time leading to eutrophication, and the seasonal turnover of nutrients in deep lakes.
Lakes and reservoir
Lakes and ponds are bodies of relatively still, or standing, water.
Although no definite size distinguishes a lake from a pond, lakes generally are larger and deeper than ponds.
Water enters lakes from streams and rivers, by rain or snow falling on or near the depression, and from groundwater.

HOW PHYSICOCHEMICAL PARAMETERS OF WATER CHANGE WITH DISTANCE IN A LAKE: CASE ...
Pollution resulting from unsustainable agricultural and urbanization activities in the Ruhezamyenda and Bunyonyi catchments are threatening lake Bunyonyi. These have led to high chemical oxygen demand (COD), electrical conductivity, turbidity, pH, iron (II) concentration and low dissolved oxygen (DO5). In this study we have investigated the how COD, turbidity, pH, concentration of iron, total suspended solids, total nutrients and DO5 of water changed with distance in lake. Water sampled from different distances in the lake filtered using Whatman paper at ambient temperatures was tested for COD, electrical conductivity, turbidity, total nutrients, iron, hardness and DO5. COD was 20.8±.0.03mg/L to 16 ± 0.03mg/L; total hardness was 16.5±0.2 mg/L to 18.6 ± 0.3 mg/L total nitrate was 103.5± 2 mg/L to 88 ± 3 mg/L; total phosphate was 100.8 ±.2.5 to 87± 3 mg/L; high TSS values from 3.4 ± 0.1 mg/L to 2.5 ± 0.1 mg/L showed contamination of water. As pH decreased from 8.3 ± 0.03 to 7.6 ± 0.04 revealed that bases were getting removed. The turbidity dropped from 25.7 ± 0.3 NTU to 20 ± 2 NTU due settling down of sediments. Iron (II) concentration ranging from 1.1± 0.1 to 0.8± 0.1 mgL-1 . Dissolved oxygen decreased from 7.9 ±0.3 mg/L to 4.8 ± 0.2 mg/L indicating surface water can uphold life of aquatic organisms. Total hardness ranged from 0.22± 0.05 to 0.19± 0.05 mg/L Electrical conductivity was high and ranged from 130± 5 to 150± 5 µS/cm indicating presence of electrolytes. Lake Bunyonyi water is not greatly polluted, but requires to be safe guarded against poor unsustainable agricultural practices, sewage draining from towns, schools and hotels in nearby settlements.

This document discusses various types of environmental pollution including water pollution, soil pollution, noise pollution, and acid rain. It outlines the causes and effects of each type of pollution as well as potential measures to address them. Water pollution refers to contamination of water bodies caused by human activities and can harm aquatic plants and organisms. Soil pollution occurs when chemicals enter the soil and alter its natural environment. Noise pollution increases the risk of health issues like headaches and heart problems. Acid rain was discovered in 1971 and forms when emissions from vehicles and industry combine with water vapor in the atmosphere. It damages ecosystems and releases toxic chemicals like aluminum into water and soil.
July 30-130-CIG-Joseph Sweeney
The document discusses removing legacy impairments from mill dams to improve water quality. It summarizes a presentation on using lidar data to identify erosion hotspots and prioritize restoration efforts. Lidar analysis of a breached dam site found 30,000 cubic meters of erosion in 3 years, releasing about 13,000 tons of sediment annually. Over 1,000 mill dams have been identified in historic county maps, with many still impairing streams. Restoration projects can significantly reduce sediment, nutrients, and increase water storage capacity.
STRATIFICATION OF FRESHWATER ECOSYSTEMSTRATIFICATION OF FRESHWATER ECOSYSTEM
This document provides an overview of freshwater ecosystems, including types, characteristics, and flora and fauna. It discusses the two main types of freshwater ecosystems: lentic systems, which include ponds and lakes, and lotic systems, which include streams and rivers. For ponds and lakes, it outlines the different zones from littoral to profundal and describes characteristics like temperature variation. It also discusses general characteristics of streams and rivers like temperature differences between headwaters and mouths. Finally, it provides some examples of common plant and animal life found in freshwater ecosystems.
Low flows issues
Low flows refer to reduced water levels in rivers caused by drought conditions, dam construction which regulates downstream flow, and over abstraction of water. This can lead to water shortages, deteriorating water quality, increased sedimentation, and ecological changes.
Two case studies are examined: the Colorado River in the US, where growing demand from agriculture and urban areas has left little flow reaching the Gulf of Mexico and increased salinity; and the River Wylye in Wiltshire, UK, where groundwater abstraction reduced typical summer flows by 50-60%, harming fish stocks and increasing algal growth.
Causes of the River Derwent Flood, 2009
The 2009 flood in the River Derwent, Cumbria was caused by both physical and human factors. Physically, warm moist air dropped over 400mm of rain in 24 hours, breaking the UK record, which was too much for the ground to absorb. This caused overflow that rapidly filled streams and rivers like the Derwent and Cocker. At their confluence, high discharges combined to cause flooding in Workington. Human factors were urbanization increasing impermeable surfaces and faster water flow into rivers, and blocked or inadequate sewers in towns like Cockermouth and Keswick that caused flooding.
APES Ch. 8, part 2
This document summarizes key aspects of freshwater ecosystems, including different types of standing and flowing water. It describes the various zones that exist in lakes and ponds based on depth and sunlight exposure. These zones include the littoral, limnetic, profundal and benthic zones. The document also discusses different types of lakes based on their nutrient levels, such as oligotrophic, eutrophic, and mesotrophic lakes. Additionally, it outlines the three zones that generally make up watersheds - the source, transition, and floodplain zones - and notes some characteristics of each. Finally, the document lists several human impacts that threaten freshwater ecosystems like dams, levees, pollution, and loss of
Aquatic biomes
There are two main types of aquatic biomes: freshwater and marine. Freshwater biomes include lakes, ponds, rivers, streams, and wetlands. Marine biomes include oceans, coral reefs, and estuaries. Both freshwater and marine biomes can be physically stratified based on variables like light, temperature, and nutrients. Primary productivity in aquatic ecosystems is limited by available light, nutrients, and temperature, with nutrients often being the limiting factor for growth.
Lakes of the world
Studying the geomorphology of lakes is a part of earth science studies. The presence of a lake, in any region, greatly influences the life of the people, living adjacent to it. There are several kinds of lakes in the world. Their characteristics are explained in this module.
Carlisle floods jan 2005
Carlisle, located on the flood plain of the River Eden where three rivers meet, has a long history of flooding. The January 2005 floods were caused by exceptionally heavy rainfall that saturated the ground and led to rapid rising of river levels. Over 2,700 homes were affected, three people died, and costs were estimated at over £400 million. Impacts included homes flooded to the second floor, emergency services stations flooded, and difficulties with evacuation efforts. Responses involved immediate evacuation of people and relief centers, as well as long-term plans for flood management schemes and engineering solutions.
Lake restoration
I designed a restoration and conservation plan to improve the island habitat and native special at the Cedar Creek/Lake Muhlenberg region of Allentown, PA. My research proposal was part of an interdisciplinary Sustainability Studies course where each student selected a real environmental issue facing the City of Allentown in which the Parks and Recreation Department desired to improve. My proposal was actually picked up, funded by, and put into action by various partners who contributed their expertise to the project, such as the Edge of the Woods Nursery in Allentown, a nonprofit organization Friends of the Allentown Parks, and the Lehigh Valley Chapter of the National Audubon Society
Freshwater ecosystem
This document defines and describes different types of freshwater habitats. It identifies lentic habitats as calm standing water and lotic habitats as running water. Major freshwater habitats include lakes, ponds, rivers, streams, springs, and wetlands. The document also discusses the thermal stratification of lakes and classifies four types of lakes: oligotrophic, eutrophic, mesotrophic, and hypereutrophic.
Impact of dams on river
Dams provide benefits like water regulation and power generation but also have negative environmental impacts. They block sediment flow and change water quality, quantity, and temperature downstream. This disrupts the local river ecology and harms fish. Over 40,000 large dams have been constructed worldwide, altering circulation systems. Specific impacts include erosion, siltation of reservoirs, salinization of irrigation water, and disruption of natural cycles that aquatic plants and animals depend on. While dams provide irrigation and flood control, they also submerge land and wildlife habitats.
#5 - Comp Plan - Groundwater
This document discusses groundwater storage and flux in the Coon Creek Watershed District. It outlines the surficial geology including lake deposits and river terrace deposits. The generalized geology profiles from west to east and in the upper 120 feet are presented. Implications are discussed such as more available groundwater storage, more infiltration, difficulty maintaining surface water resources, and groundwater resources behaving differently. Expectations for management include increased irrigation demand, and increased recreational/aesthetic use concerns.
Categorisation of limnetic fisheries resources
This document categorizes and describes different types of limnetic (inland water body) fisheries resources. It discusses lacustrine (lake) systems, including zonation patterns in lakes and thermal stratification. It also covers rivers, cold water bodies, wetlands including flood plains, and threats/conservation efforts. Key points include descriptions of eutrophic, oligotrophic, and mesotrophic lakes; types of wetlands like swamps, marshes, bogs, and fens; fish diversity in different systems; and impacts of habitat loss.
stratification of water environments -
The document stratifies different aquatic biomes as follows:
1. Freshwater biomes include ponds, lakes, streams and rivers. Ponds and lakes are divided into littoral, limnetic and profundal zones. Streams and rivers have headwaters, middle sections and mouths.
2. Transitional waters between freshwater and saltwater include estuaries and wetlands. Wetlands are divided into mineral soil and organic soil types. Estuaries have four formation types.
3. Marine biomes include the intertidal zone, neritic zone, oceanic zone and benthic zone. The intertidal zone is the area between high and low tide lines with changing conditions
Marine biome
The document discusses the marine biome, including estuaries like Elkhorn Slough, coral reefs, oceans and ocean zones. It explores how the marine biome affects life on Earth through water, heat and oxygen. It also addresses issues facing the marine biome.
Aquatic biomes
This document summarizes the major water biomes on Earth. It notes that 75% of the Earth's surface is covered by water and that most of the biosphere consists of aquatic ecosystems. It then describes the main zones of both freshwater and saltwater environments, including photic and aphotic zones, benthic zones, categories of freshwater (rivers, lakes, wetlands), coastal wetlands, estuaries, and marine zones. It provides examples of characteristic organisms found in each biome.

Risk and the wilderness
Mike Link discusses the role of risk in wilderness experiences. He recalls conversations with his son about accepting risk as part of enjoying wilderness areas. While his son later died in a kayaking accident, Link believes risk is an inevitable and necessary part of experiencing wilderness. He argues that wilderness areas need to allow for getting lost and facing dangers in order to provide meaningful experiences that allow people to challenge themselves, discover independence, and respect life. Removing risk would remove important qualities that help people understand themselves and nature.

Oregon has abundant water resources but also faces challenges from climate change. Precipitation and river flows vary greatly over the year and between years. Rising sea levels and increased coastal erosion threaten coastal areas, while longer dry periods impact water supply. Equitable access to water is important for human and environmental justice.
Make Sure You Know....
The document discusses the formation of waterfalls and meanders. It explains that waterfalls form where bands of hard and soft rock create overhangs that eventually collapse, deepening the plunge pool. Meanders form an asymmetrical cross-section due to faster, deeper flow on the outside bend eroding a river cliff, while slower, shallower flow on the inside deposits alluvium in a slip-off slope. Ox-bow lakes form when meander loops are cut off during floods.
8 physical regions of north america social studies
The document provides an overview of the 8 major physical regions of North America, summarizing the key characteristics of each:
1) The Appalachian Region contains mountain ranges from Newfoundland to Alabama, with rolling hills and valleys formed from erosion. Economic activities include mining, forestry, fishing, and chemical industries.
2) The Coastal Plains extend along the Atlantic and Gulf coasts, with flat, low-lying land and marshes. Economic activities include fishing, tourism, and farming. Environmental concerns include urban sprawl and air/water pollution.
3) The Great Lakes-St. Lawrence Lowland region has a rolling landscape near the Great Lakes, with manufacturing as a major industry. Environmental
Great Lakes Climate Global Warming Presentation
The document discusses climate change impacts in the Great Lakes region based on a conference presentation. It finds that (1) the climate is already changing, with temperatures rising especially in winter and other impacts like shorter ice cover, (2) these changes will exacerbate existing problems like worsening water resources and human health issues, and (3) common sense solutions exist now but it is unclear if governments, industries and citizens are adequately preparing for these challenges.
Niagara
Niagara Falls is located between Lakes Erie and Ontario along the border of the United States and Canada. The falls began forming around 12,000 years ago as the Wisconsin Glacier receded, cutting off outlets for the lakes and forcing water over a resistant limestone ridge. Today, the falls are composed of both the American Falls and the larger Horseshoe Falls, though historically there was just one large waterfall. Erosion of the falls has retreated them around 393 meters since first being recorded in 1678, though human intervention like hydroelectric plants has reduced the erosion rate significantly in recent decades.
Hydrosphere add By Muhammad Fahad Ansari 12IEEM14
The document discusses the structure and distribution of Earth's hydrosphere. It notes that 96.5% of water is found in oceans, with the remaining 3.5% being fresh water distributed between ice (1.762%), groundwater (1.7%), surface fresh water (0.014%), and the atmosphere and soil (0.002%). It also describes the locations of fresh water including rivers, streams, lakes, aquifers, and wetlands. Finally, it discusses the roles of the hydrosphere, cryosphere, and atmosphere in weathering land surfaces and influencing climate through ice ages and global warming.
Climate and its effects on soil
Climate affects soil formation over long periods of time through factors like temperature, rainfall, humidity, wind, and solar radiation. Temperature and rainfall particularly influence soil processes, with high temperatures speeding up organic matter decomposition and rainfall impacting soil pH, runoff, and organic matter levels. Climate change is expected to alter temperature and rainfall patterns, disrupting nutrient cycling in soils and their ability to support plant life and sequester carbon.
08 water supplies
The document discusses issues related to global water supplies and how climate change may impact availability and access to freshwater. It notes that most available freshwater comes from groundwater aquifers and surface water sources like rivers and lakes. Climate change could impact precipitation patterns and amounts, increasing demand for water while reducing supplies in some areas. This may exacerbate existing problems like overpumping of groundwater causing saltwater intrusion or land subsidence. Reduced snowpack and earlier snowmelt also threaten to diminish surface water supplies in many regions. Adapting to and mitigating these impacts, such as through improved infrastructure and water conservation, will be an important challenge.

The document aims to explain these concepts and factors to know terms related to flooding and river discharge.
8 physical regions
The document describes the 8 major physical regions of Canada:
1. The Arctic Plains are very flat with few plants able to grow in the cold climate and short summer. Economic activity includes mining, fishing, and oil/gas drilling. Climate change poses a major environmental concern.
2. The Great Lakes-St. Lawrence Lowlands have a moderate climate influenced by the Great Lakes. Agriculture, fishing, and tourism are important economic activities but the region faces ongoing environmental stresses.
3. The Canadian Shield has boreal forest and varying climate depending on location. Recreational activities and acid rain are concerns.
4. The Interior Plains were heavily forested but now feature agriculture, mining, and oil/
Floods causes & impacts
Flooding can be caused by both physical and human factors. Heavy rainfall, snowmelt, steep drainage basins, and coastal influences can increase flooding risk naturally. Human activities like urbanization, deforestation, and improper infrastructure development exacerbate flooding through reduced infiltration and faster runoff. Flooding can have severe social and economic impacts through property damage, transportation disruptions, and health issues, but may also provide benefits like fertile soils under some circumstances. Risk analysis aims to estimate the probability and potential impacts of flood events.
Yr 11 Rivers Revision 2009
- A drainage basin is the area of land where rain and snowmelt drains into a body of water, such as a river, lake, reservoir or sea.
- Larger drainage basins contain many tributaries that feed into the main river channel. This increases the risk of flooding.
- Impermeable rock and soil, steep slopes, deforestation and heavy rainfall all increase surface runoff in a drainage basin, raising flood risk. Controlling land use and replanting trees can help reduce this.

Sand Minning
Sand mining can be done through open pits, dredging river beds, or beaches. It is used to extract sand for construction and manufacturing, as well as minerals like titanium. However, sand mining risks damaging habitat, altering river flows, and increasing turbidity. It can degrade instream and riparian environments by removing vegetation, disturbing river beds and banks, and lowering water tables. Proper siting and monitoring of mining is needed to reduce environmental impacts.
Wyoming project(1)(1)
The document summarizes water resources in Wyoming. It notes that the largest water users are for crop production to feed livestock. The major water supply sources are surface water from river basins, groundwater throughout the state, mountain snowpack which provides around 70% of the supply, and reservoir storage. Wyoming relies heavily on its snowpack and surface water sources, making it vulnerable to climate change. The document also lists some of the major reservoirs in Wyoming.

This document discusses aquatic biodiversity and ecosystems. It describes different aquatic life zones like coral reefs, estuaries, and wetlands. It explains that these ecosystems provide important services like supporting fisheries and tourism. However, it also notes that human activities like pollution, development, and climate change are degrading aquatic environments and threatening biodiversity. Key threats include coastal development, overfishing, pollution from agriculture and cities, and warmer ocean temperatures causing coral bleaching.
ARID ENVIRONMENT AND ASSOCIATED PROCESSES
1. Arid environments receive very little rainfall, less than 25 cm per year, and cover over one-fifth of the Earth's land area. They experience high rates of evaporation and low humidity.
2. Aridity is caused by climate factors like atmospheric circulation patterns that limit rainfall, continentality which prevents moisture absorption over land, and mountain ranges that create rain shadows, as well as tectonic processes and human activities like overgrazing.
3. In arid regions, sediment is transported mainly by suspension, saltation, and creep, and weathering occurs through thermal expansion and contraction, salt crystal growth, and hydration/dehydration of minerals. Zones of net erosion that

Mc phee pres
The Atchafalaya River was originally a small stream flowing from the Mississippi River to the Gulf of Mexico. In 1839, when a logjam blocking the river was cleared, it allowed the Mississippi to carve a deeper channel through the Atchafalaya River bed. This started the Atchafalaya River's tendency to capture the flow of the Mississippi River and divert it into the shorter route to the sea. The U.S. Army Corps of Engineers then developed a plan to control how much water flows from the Mississippi River into the Atchafalaya River.

Forest history and management
The original vegetation of Minnesota consisted of deciduous and coniferous forests. Early European exploration and logging followed the waterways, which were the primary means of travel. The large pine forests located between the Mississippi and St. Croix Rivers were heavily logged within 30 years in a non-sustainable manner. This led to catastrophic fires in 1871, 1894, and 1918 that destroyed millions of acres and killed thousands due to poor logging practices and a lack of seed sources to regenerate the forests. After the fires, sustainable forest management practices were implemented, including setting land aside and requiring forest management plans.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

- 39. * Aids invasive species – both terrestrial and land. Shifts fish population to deeper water. Creates thermal bar that can lead to hypoxia in bays
- 41. * Over all precipitation up. Individual severe storms increase dramatically. Between severe event – drought and drying. Winter storms break up ice cover. Lake effect snow changing to lake effect winter rain
- 44. * Reduced ice pack creates more evaporation Overall lake level will lower Lower lakes will lower more than Superior and put pressure on Superior to fill their basins Lower lake levels also impact the ground water reservoir

- 49. * More winds, more waves, altered shorelines – means more erosion.
- 50. * Shipping depends upon hauling large volumes of materials in and out of ports. Ports maintain minimum clearance for ships. Cost of dredging, reshaping harbors is large.
- 51. * Long summer stratification will increase oxygen depletion – especially in lower great lakes and Lake Superior bays. Increase in invasive species Invasive species will be favored over native fish Wetlands will be damaged and dried
