A flood forecasting module of the independentlydeveloped distributed hydrological model EasyDHM is developed mainly aiming to support the flood operational management. In this flood forecasting module, the accuracy of hydrological simulation is the most important task. In order to increase accuracy, some new techniques such as the management of initial parameters, management and adaptive interpolation of realtime weather information data, autocalibration of parameters, real-time flood correction, and multimodel combination techniques are introduced to this module. The module is then applied to the Nen River basin in China for confirmation of results. It is revealed that the accuracy of simulation results from the flood forecasting module is obviously higher than that from regular simulation in EasyDHM, and this independent flood module is of great importance for flood forecast and management projects.
