Groundwater potential mapping in Bosso Local Government Area, Niger State, Nigeria

Abstract

This study assessed groundwater potential zones in Bosso Local Government Area, Niger State. SRTM dataset was used to derive DEM, Slope, drainage network, drainage density network, convergence index and groundwater potential zones using hydrological tools and weighted overlay analysis in the ARCGIS environment. Results revealed that, groundwater potential zones were classified into three classes as High, moderate, and low zones which covered 128.54k㎡(8.10%),1315.27k㎡(82.83%),and 144.06k㎡(9.07%)respectively. This groundwater potential information will be useful for effective identification of suitable locations for extraction of water. Furthermore, it is felt that the present methodology can be used as a guideline for further research.
