UNESCO G-WADI and Princeton Climate Analytics have developed a new Flood and Drought Monitoring and Forecasting system for Mozambique & Zimbabwe with a 0.05° (∼5 km) resolution. The system is based on the continental African Flood and Drought Monitor (AFDM), which has been updated to a higher resolution near real-time system using a combination of existing datasets used in the operational AFDM and newly available datasets. The product is intended to provide advance warning of impending floods and droughts.
The hydrological model, which provides daily, freely accessible historic data and forecast ensembles for several key hydrological variables, including soil moisture, evaporation, runoff, and streamflow. The meteorological forcing is derived by merging a wide range of station, satellite, and atmospheric model data to obtain the best possible predictions across all climate zones in Mozambique & Zimbabwe. The runoff estimates from HBV are routed downstream using a highly computationally efficient RAPID discharge routing scheme, which increases the resolution and robustness of the streamflow predictions.
