Capability of Satellite Rainfall Products in Simulating Streamflows in the Black Volta Basin

The study employed pairwise statistics (BIAS, R and NSE) to assess the potential of five different satellite rainfall products (CHIRPS, PERSIANN, TRMM, RFE, and ARC) in reproducing the hydrology of the Black Volta Basin. This was achieved by using the HEC-HMS model calibrated with observed streamflow data from three gauged stations (Lawra, Chache and Bui). The study showed that the model is robust and capable of reproducing daily streamflow in the study basin with marginal BIAS (− 21.1–0.32
