Groundwater potential zones for Agriculture purpose by Using Remote Sensing, GIS and AHP techniques in Northwestern coastal basins at Ras El-Khima, Marsa Matrouh Governorate, Egypt.

The primary objective of this study is to demarcate and evaluate groundwater potential zones (GWPZs) within semi-arid basins employing a combination of Remote Sensing (RS), Geographic Information System (GIS), and Analytic Hierarchy Process (AHP). A total of eight thematic layers (including geology, geomorphology, lineament density, rainfall land use and land cover, drainage density, soil type and slope) were developed in raster format. Following the AHP methodology and rank assignment, these thematic layers were fused using the raster calculator to generate the GWPZs map. The allocation of weights to each category in all thematic maps was based on their attributes and water potential capacity using the AHP methodology. The examination disclosed that: 50.13% of the studied basins are characterized by low potential, 43.81% are identified as having moderate potential, and 6.06% are recognized as demonstrating high potential.
