introduction groundwater resources in arid-semiarid zones universally suffer from problems of over-abstraction and declining water tables. in addition to the issues related to quantity, degradation of groundwater quality now assumes major importance in the arid and semiarid regions. in such areas, natural factors such as the low precipitation, combined with high evapotranspiration, result in hi...

Groundwater recharge from rainstorms can be vital for regional water resources. With the expansion of the need for more water in some specific regions under global climate change, groundwater is being pumped at a far greater rate than it can be naturally replenished. Considering that excess rainstorms could be utilized for groundwater recharge to lessen the declining tendency of regional ground...

The safety of groundwater resources is a serious issue, particularly when these resources are the main source of water for drinking, irrigation and industrial use in coastal areas. In Italy, 85% of the water used by the public is of underground origin. The aim of this report is to analyze the main factors that make groundwater vulnerable. Soil characteristics and filtration capacity can promote...

Groundwater Exploration is the one of the burning issue in nature and environmental science. At present time, India is leading towards major water crises. Groundwater will be the most exploited natural resource in future. Therefore, it is need of the time to have efficient and precise exploration of groundwater resources. There can be various methods to save earth from these groundwater crises ...

During the last decades there is low flow in the Euphrates River then consequently low flowin Hilla River which is branch of Euphrates River, Iraq. The Tyass Barrage constructed to lift thehydraulic head upstream in Hilla River raised the groundwater table above ground surface.Environmental problems have been occurred in Hashimyia Area, Babylon Governorate, causingflooding an ar...

The study area consists of eight upazilas of north-west region of Bangladesh. This is one of the driest parts of Bangladesh, normally less rain from November to April. The study area has been irrigated using about 2100 Deep Tubewells. It covers only about 80% of the total cultivable area. The remaining 20% area has been planned to cover by installation of additional Deep Tubewell under Banglade...

The provision of water supply and sanitation services to the developing and water scarce areas of South Africa is one of the goals of the Reconstruction and Development Programme. One of the principles of the South African National Sanitation Policy stipulates that sanitation systems which have unacceptable impacts on the environment cannot be considered to be an adequate form of sanitation. Th...

a study of changes in groundwater resources of najafabad plain is an important issue asregards water resources management, especially after dry becoming of zayandehroodriver. in the present study trend analysis was conducted on groundwater level of 33piezometeric stations, located in najafabad plain during 1374-1391 while using mann-kendall non-parametric test. the slope of trend line was estim...

In large canal irrigation project areas, integrated management of surface and groundwater resources can improve water use efficiencies and agricultural productivity and also control water logging. Such integrated management requires an estimation of spatial distribution of recharge and ground water flow in the underlying aquifer. Recharge occurs both as percolation losses from fields and seepag...

For the frangible ecological environment, it is very important to reasonably develop and utilize groundwater resources in Northwest China. Shallow groundwater level is an essential factor related to the eco-environmental problems such as oasis degeneration and land salinification. The lack of groundwater dynamic data is a critical concern for water resources management in the arid region. This ...
