Application of Fuzzy Logic and Fractal Modeling Approach for Groundwater Potential Mapping in Semi-Arid Akka Basin, Southeast Morocco

Groundwater potential delineation in the Akka basin, southwest Morocco, has been determined through combination of geospatial techniques and geological data. The geometric average expected value are two multi-criteria approaches used to integrate a set factors–data for which weights each factor assigned using fuzzy logic function, transforms values factors influencing groundwater presence range [0, 1]. efficiency this study lineament density, node drainage distance from rivers, lineament, permeability, slope, topographic witness index, plan curvature, profile curvature. Thereafter, map was generated GIS environment. To assess compare models, well data existing basin were choose most efficient model. For that reason, prediction area (P–A) graph, normalized density (Nd), its weight (We) applied estimate capacity model predict target area. analysis shows (Nd = 1.86 We 0.62) is more than 0.96 ?0.04). results can be future planning management water resources basin.
