Abstract: The objective of this study was to simulate hydrological responses to climate change for the southern Mkomazi river basin in Tanzania, Africa, using the model “Hydrological Predictions for Environment” (HYPE). The model which best described the relationship between hydrological fluxes and catchment characteristics was influenced by topography, soils and land-cover. A flow network connecting sub-basins to the outlet of a catchment in the Mkomazi basin was constructed. Past-present hydrological response was simulated for the period 1964–1983. Sensitivity analysis revealed that total runoff is more sensitive to rainfall than evapotranspiration and soil moisture. Hydrological response under global climate change was simulated for the period 2046–2065 using the IPCC A2 greenhouse gas emissions scenario. The ensemble mean runoff changes were mostly the result of precipitation changes, the annual riverflow is predicted to increase by 7%, and by 5% (4%) for maximum (minimum) monthly riverflows.
