Abstract:
      By using GIS and different factors influnced over water potenial of rock and alluvial unites in Arak-Mighan watershed, we determind area has water. We prepared maps such as geology, geomorphology, rain, fault density, electric conductivity, and well density and composed using GIS and produced a lot of pollygons. Each pollygon has a degree based on influenced factors. Therefore, there formed homogen polygon and discriminated priority area for water potential.
