Background and Objective: Groundwater resources are the most valuable resources of each country. Development of agricultural activities in Ardabil plain and over-use of fertilizers and pesticides, improper disposal of municipal sewage and industrial areas are responsible for groundwater pollution. Clean-up of groundwater resources is very difficult and expensive. One of suitable method in preve...

Joint assessment of groundwater-surface water resources can help develop sustainable regional water management plans for intensive agriculture. In this study, we estimated allowable groundwater and surface water quantities using a water balance model, WetSpass-GMS, for the Sanjiang Plain (10.9 × 104 km2), one of the most important grain production bases in China. We then applied a double contro...

in developing and newly industrialized countries, population growth and migration contribute immensely to the development of megacities and mega urban areas. in most cases, the rapid development ofcities has far-reaching consequences for the ecosystem in general and the hydrological cycle in particular. the developments in china within the last decades show an interesting, but complex setting. ...

over-exploitation of groundwater resources in Chaharmahal va Bakhtiari province led to prohibition of some plains in this province. One of these plains is Sefiddasht aquifer. Artificial recharge can be an effective method to raise the groundwater table and resolve the groundwater crisis in this province. The most important step for successful accomplishment of artificial recharge is locating su...

Groundwater depletion is becoming a serious policy concern in many developing countries but little is known about the costs of groundwater depletion. I use annual deviations of depth to groundwater from 1999 to 2003 from the 1985-1995 decadal means for Indian districts, to investigate how production and sown area respond to groundwater fluctuations. I find that a 1 meter decline in groundwater ...

An assessment is made on the current groundwater use and further development potential in the hard to reach (HtR) areas of Bangladesh following a combination of secondary literature review and synthesis of primary information gathered from the fields. Also, primary analyses of groundwater quality, levels, recharge and use were done using secondary data. The findings reveal that the hydrogeology...

Groundwater management practices need to take hydrogeology, the agro-climate and demand for groundwater into account. Since agroclimatic zones have already been demarcated by the Government of India, it would aid policy makers to understand the status of groundwater recharge and discharge in each agroclimatic zone. However, developing effective policies to manage groundwater at agroclimatic zon...

Groundwater, a special hydrological variable and freshwater resource is completely inter-reliant with hydro-metorological, topographic, land use and hydro-geological components of hydrologic cycle. Trend of hydrologic componentsfor future prediction is attempted to confer in this study using Man-Kendall test, linear regression and geometric progression analysis on recorded data collected from r...

Although changes in depth to groundwater occur naturally, anthropogenic alterations may exacerbate these fluctuations and, thus, affect vegetation reliant on groundwater. These effects include changes in physiology, structure, and community dynamics, particularly in arid regions where groundwater can be an important water source for many plants. To properly manage ecosystems subject to changes ...

groundwater is the main source of potable water in most areas of mazandaran province, like sari and babol city. thus the safety of groundwater supplies is very important in these regions. unfortunately attention to groundwater quality has remained limited in iran. in recent years, the growth of industry, technology, population, and water use has increased the stress upon both land and water res...
