Three common empirical estimate-methods of reservoir bank landslide surge are introduced. They are American Society of Civil Engineers recommended method

PAN Jia-zheng method and IWHR empirical formula method. For the landslide surge prediction of Egongdai ancient landslide in Lechangxia Reservoir

three common empirical estimate-methods were adopted and a physical model with geometric scale of 1:150 is constructed. Surge generated by different sliding velocity are calculated and tested under the design flood level and normal water conditions. By comparing the results of surge height of hillside on the opposite bank of the point of water entry of landslide

dam location and B3 measuring point

it is shown that the calculation results of three common empirical estimate-methods are quite different; and the results of Pan Jia-zheng method agree with the test results best. Through the further analysis of the differences between calculated results of three common empirical estimate-methods

PAN Jia-zheng method is recommended when using the empirical estimate-methods to predict reservoir bank landslide surge. In addition

some phenomena appeared in the physical model test are also explained. The method recommended can be available for landslide surge prediction.
