摘要: ABSTRACTThis paper discusses the analysis and modelling of hydrological system basin Kara River, a transboundary river in Togo Benin, as necessary step towards sustainable water resources management. The methodological approach integrates use discharge parameters, flow duration curves lumped conceptual model IHACRES. A Sobol sensitivity is performed calibrated by applying shuffled complex evolution algorithm. Results show that generation three nested catchments affected landscape physical characteristics. IHACRES adequately simulates rainfall–runoff dynamics with mean modified Nash-Sutcliffe efficiency measure 0.6. Modelling results indicate parameters controlling rainfall transformation to effective are more sensitive than those routing streamflow. This study provides insights into understanding catchment’s system. Nevertheless, further in...
