Assessment of Water Resources Availability and Demand in Malete Watershed, North- Central Nigeria

Authors: Ganiyu HO, Adeogun AG, Ahmed IA

ABSTRACT

Water is one of the basic human needs and it is imperative for sustaining quality of life. If water is not properly managed, it can lead to its scarcity. In recent times, there has been high demand for water in Malete community due to the establishment of Kwara State University which attracts small scale industries and housing estates. This study assesses the water availability and water demand in Malete watershed using Soil and Water Assessment Tool (SWAT) model coupled with Mapwindow GIS. The hydrological process of the watershed was performed using 30 years weather data obtained from Nigeria Meteorological Agency (NIMET) and spatial data which include Soil map, Land use map and Digital Elevation Model (DEM) to determine the quantity of available water resource in the watershed. Water demand was also determined with average water demand per capita and projected population. Geometric growth rate method was employed to estimate the projected population based on domestic and public factors and the population data was obtained from National Bureau of statistics. From the result, the future water demand was estimated at 3.05 × 104 m3/day while the available water resources was 1.89 × 105 m3/day. Thus, the result indicated that the water in the watershed is sufficient to cater for the projected water demand.
