Application of Kalman Semi-Adaptive Updating Model in the Routing and Forecasting of Complicated Channel Flood

Based on previous research,a Semi Adaptive Updating Model for complicated channel flood routing and forecasting is investigated.The flow routing for a complicated channel is considered in combination with flood diversion and flood retarding areas.An example of the Huaihe River,a typically complicated channel in China,is given to explain how the method works.The results show that the model is reasonable,effcetive and highly accurate.
