Abstract

Reservoirs are considered as vital sources of water supply, provide hydroelectric power support, diverse aquatic habitat, and provide flood protection. Ole Dam is a hydraulic structure on the River Ole in Nigeria with 8.1 billion m3 storage capacity. The reduction of reservoir capacity of this dam has seriously complicated the water supply for potable and nonpotable applications. This reduction in the capacity is a result of sediment leaving into the reservoir of the dam through two tributaries. Simulation analysis using both hydrological and meteorological data around the site for 11-year (2000-2011) was subjected to iteration using WEPP and SWAT simulation models. The sediment load leaving into the reservoir is a function of rainfall depth, the gradient of reservoir site, soil formation and runoff generated. Maximum average sediment load value of 10.2*103ton/ha with rainfall depth of 75.4 mm and surface runoff of 34.2 mm were generally observed in month of September for the simulation period.
