APPLICATION OF A DISTRIBUTED BIOSPHERE HYDROLOGICAL MODEL TO MEDJERDAH BASIN, NORTHERN AFRICA

To reduce flood damages due to heavy rainfall events, a timely flood alarm warning becomes a crucial issue. Since high potential evaporation can be expected in semi-arid regions, a water and energy budget-based distributed hydrological model was employed. This study attempts to forecast flood peaks using quantitative precipitation forecast and satellite rainfall TRRM, additional to the in-situ data, in order to contribute to the River management and adaptation to climate change. The approach was applied to Medjerdah River basin in Northern Africa showing the feasibility to support flood management.
