Mapping Potential Areas for Groundwater Storage in the Middle Moulouya Basin (Morocco): Contribution of Remote sensing and Geographic Information System.

EasyChair Preprint 3134

Abstract

The main objective of this study is to identify groundwater storage areas in the middle Moulouya Basin by using Geographic Information System (GIS) and Remote Sensing (RS) methods. Five thematic maps of lithology, slope, rainfall, rock fracture and drainage were respectively categorized and weighed, and then used to create the map of potential groundwater storage areas. The results have shown that the area of very low to low potential surfaces represents approximately 10% of the total area, indicating that the middle Moulouya Basin is rich in groundwater, where more than 2200 wells and boreholes have been drilled. The obtained results have been validated with specific yield of springs in the study area. It indicates a clear correlation between the groundwater potential zones and the specific yield, this correlation is particularly obvious in light of flows of water points and their locations, indeed, most of water points with high flows are located in excellent potential zones while poor potential zone includes the majority of water points with low flow.
