Although arsenic contaminated groundwater in Bangladesh is a serious health issue, little is known about the complex transient patterns of groundwater flow that flush solutes from aquifers and carry solutes into the subsurface. Hydrologic modeling results for our field site in the Munshiganj district indicate that groundwater flow is vigorous, flushing the aquifer over time-scales of decades to...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

Knowledge of soil moisture dynamics in the unsaturated soil zone provides valuable information on the temporal and spatial variability of groundwater recharge. This is especially true for the Mediterranean region, where a substantial fraction of long-term groundwater recharge is expected to occur during high magnitude precipitation events of aboveaverage wet winters. To elucidate process unders...

The groundwater flow system is typical dissipative structure system, and its evolution can be described with system information entropies. The information entropies of groundwater in Shijiazhuang City had been calculated between 1960 and 2005, and the results show that the entropies have a decreasing trend throughout the research period, and they can be divided into our stages based on the grou...

Groundwater resources are increasingly being relied on in rural areas for income generation and food security. However, there is currently a lack of simple, yet accessible hydrogeological tools to monitor critical groundwater resources, both for quantity and quality. This is particularly true in developing countries underlain by fractured hard rock aquifers, with low productivities. Electrical ...

Th e aims of the study were to apply, test and to present the ability of the deterministic simulation models SIMWASER and CERES-Wheat computing soil-water balance components, percolation losses, ground water recharge and capillary rise. Two case studies for the assessment of percolation losses from irrigated carrots to deep groundwater at Obersiebenbrunn in the Marchfeld (Austria) and ground wa...

F Pesticide Contamination Prevention Act authorrzed the California Department of Food and Agrculture to modify w.es of pesticides in areas where they have leached through soil to groundwater (Connelly, 1985). Leaching of agriculhuaI chemicals has been shown to occur during recharge of groundwater whereby water moves from the surface through the soil profile to a groundwater aquifer (Wehtje et a...

Finance Minister of India, in 2007 Government of India launched the Dug Well Recharge Scheme as a national program with an outlay of Rs. 1800 crore. Its aim was to educate and incentivize farmers in 100 hard rock districts of the country to modify their open dug wells for groundwater recharge. However, after around 3 years of operation of the scheme, our review found that it failed to achieve m...

artificial recharge can be an effective method to raise the groundwater table and to resolve the groundwater crisis in sefid dasht plain. the most important step to successful accomplishment of artificial recharge is locating suitable areas for artificial recharge. hence this research carried out with purpose of determining suitable areas for artificial recharge in sefid dasht plain. slope, sur...
