Abstract

Accurate information on catchment’s sediment yield is inevitable for improved catchment and water resources management. This study assesses the levels of sediment loads in the Pra River Basin, Ghana and explores its spatial variabilities. The determination of the sediment yield involved field work and laboratory analysis. River discharges were measured using acoustic Doppler current profiler (ADCP). Suspended sediments were collected using the integrated sampler. Sediment concentration analysis was performed using evaporation method whilst the data were analysed using correlation and analysis of variance. Suspended sediment concentrations and river discharges were measured and analysed at nine hydrological stations within the basin. Results indicate that sediment yields from the basin are very high (ranging between 13.29 and 215.02 tkm−2 yr−1) and differ significantly (p = 0
