The phenomenon of unbalanced discharge between the Three Gorges dam and Gezhouba dam is caused by many factors.Analyzing the importance of each influencing factor and identifying the key influencing factors leading to the unbalanced discharge between the two dams is of great significance for the hydropower scheduling and water balance analysis.This study uses Grey Correlation Analysis and Random Forest Model to identify the key influencing factors leading to the unbalanced discharge with the historical data of discharge and water level from 2018 to 2023, and selected 19 potential influencing factors. The results from both methods show the same results. The influence of generation discharge and Output Schedule are the important factors leading to the unbalance of discharge between two dams. The most important factor is power generation flow of the Gezhouba dam.
