Also, the model performance was significantly improved when bias corrected satellite rainfall input in to the model with R2 = 0.79, ENS = 0.72 for CHIRPS_2 and R2 = 0.8, ENS = 0.78 for TMPA_3B42v7 estimates. The results were indicated that the HEC-HMS model well simulated catchment runoff for both satellite precipitation products. The HEC-HMS model performance was resulted R2 = 0.78, ENS = 0.69 for CHIRPS_2 and R2 = 0.79, ENS = 0.76 for TMPA_3B42v7 satellite precipitation products during calibration periods. The Performance of the rainfall runoff hydrologic model was evaluated using Nashe Sutcliffe efficiency (ENS), coefficient of determination (R2) objective functions, relative volume error (RVE), and percentage error of peak flow (PEPF). The study area is located in Dabus watershed, Abbay basin, Ethiopia and a non-linear power law was applied for bias correction of satellite rainfall estimates for input in to HEC-HMS hydrologic model for runoff generation. As the objective of this study is to evaluate the high resolution satellite rainfall products for hydrological simulation, the Climate Hazards Group Infrared Precipitation with Stations (CHIRPS_2) and Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA_3B42v7) satellite rainfall products have been evaluated for stream flow simulation for a period of 16 years from (2000 – 2015), at daily temporal and 0.25º x 0.25º spatial resolution. However, satellite precipitation product may serve as important inputs for modeling in the area with scarce field data for a wide range of hydrological applications. Nevertheless, accurate and consistent precipitation measurement are relatively sparse in many developing countries like Ethiopia. Accurate measurement of rainfall is vital to investigate the spatial and temporal patterns of rainfall at various scale for rainfall-runoff modeling.
