The Study on Flood Wave Propagation Using Various Routing Method on Branches Reservoir Surface
Flood forecasting based on the distributed model is becoming popular in Malaysia. It is one of the methods to reduce flood risk when a structural measure is very expensive to implement. Two main outputs from the forecasting model are the timing of the flood wave to arrive in the area of interest and...

Flood forecasting based on the distributed model is becoming popular in Malaysia. It is one of the methods to reduce flood risk when a structural measure is very expensive to implement. Two main outputs from the forecasting model are the timing of the flood wave to arrive in the area of interest and the magnitude of the flood. However, another factor, which needs to be given attention, is the simulation computational time. Flood forecasting model demands a fast and accurate computation. The river channel is normally represented by river cross-section that deployed the full hydrodynamic equation.
