Abstract

This study is on simulating the level of ground water in River Mallam Sule Catchment Area of Yobe State.  Soil Water Assessment Tool (SWAT) was used in the study. The resistivity of boreholes, gravity data, climatic data, stream flow data, and land use and land cover change served as an input to the model. The Catchment boundary was delineated using DEM (90m resolution), while be AsterDEM (30m resolution) was used for drainage network in Arc SWAT 2012. The finding of the simulation revels that the eastern and southeastern part of the study area has the highest level of groundwater respectively, moderate value was observed around Potiskum while low value was observed around southwest of the study area. Therefore, SWAT has the capacity to simulate the level of groundwater in areas with deficiency in groundwater recharge and low precipitation.
