Without proper data and standard methods, assessing and determining groundwater resources in mountains and flat dry plains is difficult for a region.In this study, a GIS-based groundwater resource assessment is deemed a viable option, so the Analytical Hierarchy Process (AHP) is used to designate groundwater potential zones read more in the Balkh Province of northern Afghanistan.Several influential factors were provided for this purpose, including lithology, distance from the river, korpskaft slope, drainage density, (LU/LC), lineament density, and rainfall.

The groundwater potential zone map was grouped into four groundwater potential zones.They are very low (10.87%), low (35.

13%), moderate (30.76%), and high (30.76%).

The use of water level data was used to validate the results.The overall accuracy (71%) was found accordingly.
