Selection of Potential Sites for Artificial Groundwater Recharge

Groundwater resource management is inherently interdisciplinary; it requires a multidisciplinary analysis of data that is best addressed through a multi-criteria decision-making (MCDM) approach, which explicitly accounts for why one criterion may be more relevant to the decision-making process than another. In this study, the Analytic Hierarchy Process (AHP), developed by Saaty (1980), was used as a decision-support method to determine the weights assigned to the various criteria. Our work consists of selecting and delineating potential sites for artificial recharge. The best way to do this is to use powerful tools capable of yielding an optimal result (GIS). However, the selection of an artificial recharge site is based primarily on the following criteria: geology, geomorphology, slope, thickness of the unsaturated zone, permeability, and piezometric level.
