The DRASTIC method assumptions and the factors used in this method were discussed to examine its suitability for assessing contamination vulnerability from acidic water in the spoil heap. Factors used in DRASTIC approach, depth to water, rainfall, aquifer media, surface topography, hydraulic gradient ...
Back in Beijing, Ma Jun feels the project is a short-term "emergency measure." "It will help to buy some time," said Ma Jun. "I wouldn't call this a real final solution because the current volume of transfer will not be enough to fill up the gap." The water supply for some citi...
In South Togo, the main water resource is the continental terminal (CT) aquifer, part of the coastal sedimentary basin (CSB). However, previous studies hav
Large water bodies (e.g. lakes and reservoirs) have been the subject of great interest not only because of their water resources role but also as indicators of anthropogenic impact on water scape change. For example, closed lakes, which have no significant surface or subsurface outflow, are p...
Over the past six decades, human activities and climate change have driven complex physical and ecological changes to China's inland water bodies. For example, China has seen a remarkable reservoir development across the country and dramatically accelerated shrinkage in natural lakes in North and ...
The way I see it, what these things “erase” is mostly mundane or ugly concrete. Moreover, they accomplish some important things besides just looking pretty. First, these techniques help prevent water pollution and combined sewer overflows, something Jeff rightly expresses concern about in his ...
Localities are color coded in green (Alborz Mountains, in Caucasus biodiversity hotspot), orange (Alborz, Irano-Anatolian), red (Zagros, Irano-Anatolian) and black (Central Iranian Plateau or brackish water localities at the Caspian Sea; 31 and 41). The map was created using DIVA-GIS 7.5...
Water imbalance, in which output exceeds intake, can produce hyponatremia. True False Metabolic water is constantly produced, but it is the smallest water intake volume. True False Low temperatures are microbistatic. True False Excess body heat may be lost in the eva...
Groundwater for Sustainable Development, Volume 13, May 2021, Pages 100590 View PDF Highlights Abstract The groundwater vulnerability analysis addresses the degree of sensitivity of groundwater system towards changes in both intrinsic/inherent and extrinsic factors. With this aim, an integrated FAHP-GIS...
Nitrate contamination of groundwater often occurs in urban and industrial areas due to point and non-point sources of anthropological activities. Groundwater constitutes a a significant portion of the water supply system for Bahir Dar City in Ethiopia, though the level of groundwater pollution is no...
