These rains have significant effects on the different ecosystems of earth. In this study, in order to investigate the sensitivity of erosion and sediment yield of Gachsaran Formation to acidic rainfall and its density change, parts of the Kuhe Gach watershed area in Izeh Township are selected with the area of 1202 hectares. This investigation in order to determine productivity runoff and sediment in 8 points and with 3 replicates in Gachsaran formation in different intensities 1, 1/25 mm in min and in the intensities of distilled water and 4, 5 acidic water in four aspects of northern, southern, eastern, western with using kamphorst rain simulator was done. In order to analyze statistical was used SPSS and EXCEL packages. The highest of runoff and sediment rates in Gachsaran formation in 1, 1/25 mm in min are related to 4 acidic rainfalls. The rainfall of 5 acidic also runoff and sediment are more than the rain of distilled water. The infiltration rates in rainfall different intensities also showed a significant difference.
