Abstract:Sediment yields of different watersheds of three subcatchments have been worked out using the Musgrave and the Sediment Yield Predictive Equation. Data for the calculation were in the shape of a soil and land use map prepared by photo-interpretation with selective field check and such measurements as Relief Length Ratio, average slope percentages and particle size data for the surface 5 cm soil. Sediment yields by the Predictive Equation are markedly higher than those obtained by the Musgrave Equation. The Predtctive Equation values are also closer to the rate of sediment yields as measured at the Ukai dam site by the Inflow-outflow method; it thus appears to offer a satisfactory basis for the determination of priority subcatchments and watersheds. Based on sediment yields per unit drainage areainter se priorities have been worked out amongst the three subcatchments as well as for the watersheds within each of the subcatchments.
