• Annual evaporation from hydropower reservoirs

    Evaporation from hydropower reservoirs represents a key component of the reservoir water budget. Depending on the different climate regimes on the continent, the rate of evaporation from open water changes with region-specific temperature, wind speed, relative humidity and solar radiation. This map shows the annual mean evaporation rate (mm/year) at the centroid of African reservoirs subject to hydropower production, for the year 2016.
