The North Central Coast of Vietnam is a narrow zone with very complicated topography: mountains in the west, sea in the east. Almost all of the river basins are small, short and sloping. There is very heavy rain that occurs on a large scale and is concentrated in a short period (from 2 to 3 days) every year. In these conditions, the North Central Coast of Vietnam is the part that has a high frequency of big floods and flash floods with monstrous destructive force. The tool for simulating and forecasting these extreme floods is needed for the decision makers. In the framework of the FLOCODS project, supported by the European Commission, there is a tool for this purpose made by coupling the hydrological model MARINE and IMECH_1D hydraulic model. The models have been linked and used for flood simulating and forecasting in the Huong River Basin of Vietnam. The verification and the application of the models prove that they can be used for forecasting, evaluating of flood control measures and planning actions in emergency cases not only for this basin, but also for other river basins in the Central Coast of Vietnam. Keywords: hydrological model, hydraulic model, flood control, river basin, Central Coast of Vietnam.
