Groundwater and Watershed Analysis

The present paper is about a preliminary study of the georesources of Niamey (Niger). The main goals are the qualitative and quantitative characterization of surface water, groundwater, and aggregates. There was a census of the wells and quarries, an in situ characterization and a consequent sampling survey. Laboratory analyses were performed to evaluate chemical and physical features of water and aggregates. Thanks to a dedicated Geodatabase, schematic forms reportingthe available data of wells and quarries were produced. The study evidenced the actual condition of surface water, groundwater and active and closed quarries, also highlighting local phenomena of pollution.
