Abstract
The primary intent of the flood forecasting model development was to assist the Flood Forecasting Center (FFC) established under the Ministry of Water Resources of Energy of Ethiopia to select/develop, install, calibrate, and validate a flood forecasting and an early warning system based on rainfall runoff modeling and flood routing methodologies in the Lake Tana catchment, as well as conducting training within the National flood Forecasting Center in the Ministry.
All the documents listed above are created in the course of the flood forecasting model development undertakings. The flood forecasting modeling development includes:
·      Required input variables and parameters to the hydrological models set for Gummara, Rib, Megech and Dirma catchments
·      Easy to use integrated flood forecasting system which gives flood alert level for 72 hours ahead
·      HEC-HMS model configured as catchment based semi-distributed hydrologic model type intended to represent the spatial variation of the rainfall and the proposed hydraulic facilities such as storage dam.
·      Hydraulic configuration and modeling using HEC-RAS
The model input consists of data from three existing rainfall stations and flow data from corresponding gauging stations at Gummara, Ribb, Megech and Dirma for calibration and verification of the model.
