Summary
This paper reports the applications of the back-propagation neural network (NN) to determine wave overtopping rates of sloping dikes. The wave overtopping data of sloping dikes selected from CLASH database is used for the training and testing in the NN model. This paper first configures the optimum architecture of the NN using different combinations of input factors. The test results show that the present NN model could achieve good prediction for the dimensionless wave overtopping rates of sloping dikes using three significant physical parameters; the relative freeboard, the surf similarity parameter and the relative water depth at the toe. The results show that the present NN model obtains better predictions comparing with the previous empirical formula.
