Abstract: Daily tropical rainfall measuringmission (TRMM)-based rainfall and Landsat-derived land-cover maps were used to retrospectively simulate runoff for the Black Volta Basin. This was to ascertain the usefulness of the increasingly available satellite observation data to augment ground-measured hydro-meteorological data for unguaged basins or basinswith inadequate data. Both visual and statistical comparison of TRMM-based rainfall with the gauged rainfall indicates that themonthly rainfall data are statistically comparable. Seasonal upward adjustment of themonthlyTRMM-based rainfall improved the rainfall correlation giving a Nash–Sutcliffemodel efficiency of the simulated runoff of 89.5%. Thus, monthly TRMM-based rainfall estimate can be used to augment existing ground-measured rainfall data and together with Landsat-derived land-cover maps be used to estimate runoff for unguaged basins in theWest African sub-region. The study is useful for Sub-Saharan Africa, where sustainable water management is sometimes hampered due to the absence of reliable and consistent data.
