Long term groundwater pumping in Australia and other coastal lowland areas has led to issues like sea water intrusion into aquifers, groundwater depletion, and land subsidence. Major study locations of these effects include the Kiti Aquifer in Cyprus, Israel, and Washington; Mexico, China, Tanzania, and South Africa; and areas in India, Taiwan, the USA, and Iran. Prolonged pumping can also impact water quality through increased dissolved solids and biological pollutants. Land subsidence has been particularly problematic in Phoenix and Tucson, Arizona, causing earth fissures and damage to well casings.

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.
Disaster management-flood
This document discusses flood management and defines different types of floods. It describes floods as overflow of water beyond normal limits, especially over dry land. It discusses causes of floods such as heavy rainfall and overflowing rivers and oceans. The effects of floods include disrupted transportation, damage to infrastructure, health hazards from contaminated water, and destruction of agricultural land and crops. The document also defines structural and non-structural flood control measures. Structural methods include dams, water gates, and diversion canals to redirect flood waters.
Hydrology
The document discusses several key aspects of hydrology:
- Precipitation is the main driver of hydrologic processes and is formed as air cools and its ability to hold water decreases.
- Weather patterns result in different biomes and rainfall patterns across geographic regions.
- Water moves across and through soils via processes like infiltration, evaporation, transpiration, surface runoff, subsurface stormflow, and groundwater flow.
- The dominant runoff process depends on factors like rainfall intensity, soil saturation, and watershed characteristics, and can include Horton overland flow, saturation overland flow, or subsurface stormflow.

Surface water runoff
Runoff is that portion of the rainfall or irrigation water which leaves a field either as surface or as subsurface flow. When rainfall intensity reaching the soil surface is less than the infiltration capacity, all the water is absorbed in to the soil. As rain continues, soil becomes saturated and infiltration capacity is reduced, shallow depression begins to fill with water, then the overland flow starts as runoff.
Hydrology presentation
Hydrology is the study of water on Earth, including the hydrologic cycle, water resources, and sustainability. It involves the movement and distribution of water throughout the planet. The main domains of hydrology include surface water, groundwater, drainage basins, and water quality. Precipitation, evaporation, soil water, aquifers, floods, and water reservoirs are some of the key concepts and topics in hydrology. Major damage from floods globally costs billions of dollars annually.
measurement of infiltration
This document describes different types of infiltrometers used to measure infiltration rates of water into soil. A single ring infiltrometer consists of a metal cylinder driven into the ground filled with a fixed level of water. A double ring infiltrometer uses two concentric rings to better control lateral water flow. A rainfall simulator produces controlled rainfall over a plot of land to measure surface runoff under varying rainfall intensities and durations.
Flooding
The document discusses river drainage basins and flooding. It defines key terms related to the water cycle within a drainage basin such as precipitation, infiltration, interception, surface runoff, throughflow, evaporation, evapotranspiration, percolation, and the water table. It also explains the components of a flood hydrograph including the rising limb, falling limb, peak discharge, peak rainfall, storm flow, and normal base flow. Factors that influence the shape of a hydrograph are described such as land use, geology, soil, vegetation, and topography.
The Hydrologic Cycle
The document provides an overview of the hydrologic cycle. It begins with an introduction explaining that water circulates continuously between different spheres of the Earth. It then discusses the major components of the hydrologic cycle, including precipitation, evaporation, transpiration, runoff, infiltration, and others. Finally, it explains concepts like condensation and how precipitation forms from water vapor in the atmosphere.

The document discusses infiltration, which is the process by which water enters soil. It defines infiltration as the rate at which soil can absorb rainfall or irrigation, measured in mm/hr or inches/hr. An infiltrometer is used to measure infiltration rates. The infiltration capacity depends on factors like the soil type and moisture level, with dry soil having a higher capacity than moist soil. Infiltration is important for understanding groundwater recharge and runoff. Other factors like vegetation cover, land use, temperature, and water quality can also impact infiltration rates.
WFP Hydrologic cycle
The document discusses the most important factors for a water harvesting system. It lists climate, hydrology, topography, agronomy, soils, and socio-economics as the key factors.

Hydrological Cycle
This document discusses the hydrological cycle and properties of water. It notes that water is essential for life and makes up 71% of the Earth's surface. The water cycle is driven by solar energy and involves evaporation from bodies of water into the atmosphere, condensation and precipitation on land, runoff into water bodies, and eventual return to the oceans. Water moves through this cycle in vapor, liquid and solid forms through various processes like evaporation, transpiration, infiltration, and percolation. The cycling of water through the biosphere maintains a balanced system over thousands of years through natural recycling powered by solar energy.
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.
Impact of landuse development on a highland freshwater lake.
Intensive landuse development always be accused as the main factor to cause increase in generation of pollutants, taking the runoff as the transport medium. A study to find the relationship of landuse development and seasonal water quality changes in a highland lake, Ringlet Lake, Cameron Highland, Malaysia proves that as the percentage of watershed cleared area rised, the degree of water quality deterioration tends to increase accordingly. The study found that most of the parameter analyzed in both seasons shows that Ringlet Lake fell into Class III in the Water Quality Index, which need extensive treatment for domestic uses. The high percentage of cleared area as indicated by individual type of landuse leads to produce polluted runoff which ended up into the nearest river network, Bertam and Ringlet River and eventually entered the lake. In highland areas, a basin management of a water body should be more refined and specific in order to address focus of concerns in lake ecosytem health and quality impairment issues.

Impact of climate on groundwater
Adaptation to global change must include prudent management of groundwater as a renewable, but slow-feedback resource in most cases. Groundwater storage is already over-tapped in many regions, yet available subsurface storage may be a key to meeting the combined demands of agriculture, industry, municipal and domestic water supply, and ecosystems during times of shortage.

Sea Water Intrusion
Most of the world's population lives near coastal areas and relies on groundwater as a source of freshwater. As populations and water usage increase, aquifers are being depleted, causing issues like saltwater intrusion. Saltwater intrusion occurs when denser saltwater moves into freshwater aquifers due to changes in water pressure. The Ghyben-Herzberg principle states that for every meter of freshwater above sea level, there will be 40 meters below. Remedial measures to control intrusion include monitoring water levels, restricting pumping, using alternative water sources, and artificially recharging aquifers.

Pipe report
Soil degradation implies long term decline in soil’s productivity and its environment moderating capacity.In other words,it means decline in soil quality,or reduction in attributes of the soil in relation to specific functions of value to humans.It has plagued the earth since the dawn of settled agriculture.In ancient times ,soil degradation caused the downfall of several thriving ancient civilizations,eg.the Harappan and the Kalibangan cultures in the Indus Valley,the Mesopotamian and Lydian kingdoms in the Mediterranean region, and the Mayan civilization in Central America.During the 20th century,the increase in population has drastically accentuated the risks and extent of soil degradation.(Lal,2001). Land degradation is not being adequately addressed, but is of vital importance to raise awareness so that future land management decisions can lead to more sustainable and resilient agricultural systems. Of India’s total geographical area (328.7 Mha), 304.9 Mha comprise the reporting area with 264.5 Mha being used for agriculture, forestry, pasture and other biomass production. The severity and extent of soil degradation in the country has been previously assessed by many agencies (Table 1). According to the National Bureau of Soil Survey and Land Use Planning ~146.8 Mha is degraded. Water erosion is the most serious degradation problem in India, resulting in loss of topsoil and terrain deformation. Based on first approximation analysis of existing soil loss data, the average soil erosion rate was ~16.4 ton ha−1year−1, resulting in an annual total soil loss of 5.3 billion tons throughout the country .Nearly 29% of total eroded soil is permanently lost to the sea, while 61% is simply transferred from one place to another and the remaining 10% is deposited in reservoirs.( Bhattacharyya et al.,2015)

Model trees as an alternative to neural networks
The document compares the use of artificial neural networks (ANNs) and model trees (MTs) for rainfall-runoff modelling. It tests these techniques on a European catchment to predict runoff 1, 3, and 6 hours ahead. The results show that both ANNs and MTs produced excellent results for 1-hour ahead prediction, acceptable results for 3-hour prediction, and conditional acceptable results for 6-hour prediction. While the performance of ANNs and MTs was similar for 1-hour predictions, ANNs performed slightly better for longer lead times. However, MTs have the advantage of producing more understandable and adjustable models of varying complexity and accuracy.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
