Abstract The reservoir bank collapse is a common geological problem in the reservoir impounding process. There often exists significant difference between the prediction and the actual collapse ranges. A new method,named as balanced alluvial accumulation approach,is proposed for the prediction of reservoir bank collapse on the basis of the surveying of bank collapse cases of more than 10 large reservoirs in China,the measurement on all kinds of stable angle of collapse phenomenon,and the analysis of the applicable conditions,the collapse mechanism and the collapse factors of the current prediction method of bank collapse. The new method has the reasonable initial points and prediction parameters and overcomes the deficiency of the traditional prediction method of bank collapse. It is also verified by a case study.
