The maximum discharge generated by the collapse of rubber dam is crucial for the control and running of rubber dam in flood season. To calculate the maximum discharge caused by rubber dam collapse quickly and accurately, 102 scenarios of rubber dam collapse were designed to simulate the maximum discharge caused by dam collapse. Dam height, river slope, water storage, length of dam, and dam collapse duration and other factors were selected as variables in the scenarios. The empirical formula for estimating the maximum discharge generated by the collapse of rubber dam involving dam length, dam height, water storage, complete dam collapse duration, and lateral contraction coefficient was presented using statistical analysis method. Example verification demonstrate that the empirical formula is quick in calculating and accurate in result, and also practical and convenient.
