Trend analysis of changing stream flow of spring in khoramabad city in three times span namely month, season and annual were investigated by statistical method. The data used include data from 4Spring were selected in 40-years period (1348-1388). In this study, the slope of the linear trend in the data sample estimates with using the TSA and then with using TFPWmethodthe effect of coefficient of autocorrelation of data was eliminated, and discharge time series prewhitened, then trend changing of original and prewhitened time series with MK test were analyzed. Ultimately rend analysis of changing of station of precipitation in annual were investigated by statistical method. The results of investigation in annual based on MK_ TFPW presented. Also the results of this research show that at annual scale of stations no trend is significant at 10% decreasing of spring flow is due increase of pickup underground water.
