Geospatial modeling study reveals effective groundwater potential delineation in an arid watershed, highlighting viable locations to reduce desalination reliance.

Key Points

To identify and delineate groundwater potential zones in the semi-arid Itwad-Khamis watershed of Saudi Arabia using multi-criteria spatial analysis.
Integrated 12 thematic spatial layers into a GIS environment using weighted overlay analysis.
Applied fuzzy-analytical hierarchy process (FAHP) multi-criteria decision-making techniques to categorize potential zones into five classes.
Validated the resulting model using distribution patterns and yield data from existing open wells within the watershed.
Validation confirmed that 82% of existing open wells were located within zones classified as having very good or good groundwater potential.
Zoning analysis revealed that 14.6% of the watershed was classified as very good potential, 28.8% as good, 27.3% as moderate, and 20.2% as poor potential.
