Title

Estimation of Runoff and Erosion Simultaneous Threshold Using Erosion Different Components

Pages

  817-827

Abstract

 At the beginning of the conversion of precipitation into runoff, some of the precipitation is absorbed by the soil or penetrates deep into the earth and the rest becomes surface runoff. By determining the runoff and erosion simultaneous threshold can help to watersheds proper management. In this study, in order to determine the runoff and erosion simultaneous threshold using erosion different components in different Land uses of Gachsaran Formation, a part of the Kuhe Gach watershed of the Izeh city with an area of 1202 hectares was selected. In this study, the relationship between the runoff and erosion simultaneous threshold and erosion different components such as soil permeability and the amount of sediment and runoff in different Land uses of Gachsaran Formation was done using Multivariate regression. Then, sampling of erosion different components at 6 points with three replicates and at different rainfall intensities of 0. 75, 1 and 1. 25 mm in min, in 3 Land uses of the range, residential area and agricultural lands with the help of the device Rain simulator was performed. SPSS and EXCEL software were used for statistical analysis. The results showed that in estimating the Runoff and erosion threshold in all three-Land uses, the amount of sediment and then the degree of soil permeability had the most positive and negative effects and the amount of runoff had no role in modeling. The positive effect of the amount of sediment in general on the Runoff and erosion threshold in five cases and its negative effect in three cases and the positive effect of soil permeability in modeling in general on the Runoff and erosion threshold in three cases and affecting its negative is three cases.
