Groundwater is an important water source widely used for agricultural, domestic, and industrial activities
in the world. Increase in population, immoderate use of groundwater in agriculture, and irregular
rainfall due to climate change all have a negative effect on groundwater potential. It is important to
determine the groundwater potential of every basin to regularly monitor static water level changes. In
this study, static water level (SWL) changes in the groundwater of the Upper Tigris Basin, which is located
between the Diyarbakir Plain and northern Batman, Turkey, has been analyzed for the period 1980–2011
and modeled by using GIS techniques on the other hand, static groundwater levels identified with GIS
were used at the end of each study period to determine changes in these levels. Finally, possible reasons
of changes in groundwater levels were discussed.
