In the chosen rainfall events, it adopted the original data of the rainfall and the flow rate, and used the method of moving average to reset the rainfall and the flow rate. According to these two ways to find a proper linear regression equation for this testing area. In this research, its objects are the rainfall with the erosion, and the flow rate with the erosion,. It searches the relationship between these two methods separately, and then to find out the relationship during the testing time. According to the result of the analysis of regression, it shows that the flow rate with the erosion, has a more conspicuous relativity than the rainfall with the erosion.
