main perennial rivers of gujarat, tapi, narmada, mahi and sabarmatiare meeting arabian sea in gulf of khambhat. the out flow of mahi river intothe sea is decreased due to construction of dams like bajaj sagar, kadana, panamand wanakbori weir. so, tidal effect of sea and sea water intrusion is beingincreased on landward side. moreover, due to erratic nature of rainfall andimproper management of ...

for better understanding of tehran ground water, samples were taken randomly from 340 out of 655 deep & semi deep wells in 1993, which dug by tehran water supply and sewage engineering company. 260 water specimens were examined chemically and physically and compared with the 1993 world health organization (who) and food and agriculture organization (fao) criteria and analyzed statistically. log...

assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...
