Artificial Neural Network Model's Application in Urban Water-logging

Nowdays,the water level of downstream isn't considered in urban drainage management system.It is one of the reasons to cause urban waterlogged.The hydro model are more and more used in urban flood control,and one of the boundary conditions-river's water level is always a invariable data according experience.The ANN artificial neural network can be used to establish the hydro model to forecast the river water level base on the data of upstream hydrological and local station.So the more accurate dynamic forecasting can replace that invariable data.One drainage area is used to verify the accuracy of the ANN model,and the forecasting result prove that the ANN model can be used in urban flood control well,base on reasonable enter data and forecasting time.
