Abstract The water quality index (WQI) model is a popular tool for evaluating surface quality. It uses aggregation techniques that allow conversion of extensive data into single value or index. Globally, the WQI has been applied to evaluate (surface and groundwater) based on local criteria. Since its development in 1960s, it become due generalised structure ease-of-use. Commonly, models involve...

this research was conducted in order to study the effect of climate and geology factors on groundwater sources in mahvelat plain. in order to study the groundwater quality and quantity considering groundwater resources including wells and qanats; using groundwater surface, electric conduction (ec) and the total density solution (tds), the maps of groundwater surface fluctuation and quality para...
