Management of water resource from semiarid area by elaborating database under GIS: case of Gareb-Bouareg aquifer (Rif, Morocco)

Abstract

Geographical information system (GIS) is a very important tool in the management and protection of water resources, particularly in arid and semiarid zones. In this respect, the aquifer of Gareb-Bouareg was taken as an example and this by developing a predictive and useful decision-making tool for the control, planning, and management in real time of the recovery of the level piezometric. As an initial step, a database for processing and organizing data from various sources was developed using ArcGIS software. Subsequently, a Visual Basic application under the name “MONAGABO” was developed to facilitate the exploitation of the elaborate database. Based on this application, thematic maps, map of the conceptual model, were generated. Also, visualization and organization of spatiotemporal data as well as access to results and intermediate stages of hydrogeological modeling using MODFLOW modeling software can take place in this application. However, the ability of GIS to adapt to the management and quantitative monitoring of water resources in an aquifer has been dismantled by this application.
