Abstract

the type and intensity of SOIL EROSION in a region generally subject to climatic conditions, ups and downs, soil and land use.That in between these, land use compared to other factors is more attention. Land use and erosion close relation with each other. In this investigation in order to investigate sensitivity to yield sediment and erosion the various land uses of GACHSARAN FORMATION, part of gachsaran catchment in izeh city is selected to 1202 hectares area. This investigation to determine the relationship between the sediment produced by RAIN SIMULATOR with some soil physicochemical characteristics like percent very tiny sand, sand, clay, silt, pH, Ec, moisture, Calcium Carbonate and organic material in different land uses in GACHSARAN FORMATION to do. Then sediment samples in 6 points and with repeated three times in the intensities of various 0.75, 1 and 1.25 millimeter in minute in three land use pastures, the residential and agricultural lands to help the RAIN SIMULATOR. In order to investigate factors in sediment opportunities and erosion vulnerability, samples of soil layers in 0-20 cm meters in the same number of sampling sediment. In order to do all the analysis of statistical methods used EXCEL and SPSS 11.5 software. Then the most important factors in sediment yield are diagnosed by several factors regression. The results showed that sediment yield and erodibility in land uses, in the precipitation various intensities meaningful difference have. These regression models have showed that in the production of sediment in various land uses from between measured factors of the indexes have been quantities like silt, very tiny sand, lime, Ec, organic materials and pH have the largest role in the production of sediment. Then other parameter like run off threshold, percolation rate, sediment density in three land uses calculated. In the total the amount of runoff in residential land use in the highest and agriculture land use is lowest.The amount of sediment also agriculture land use is the highest and residential area is lowest. Run off threshold time, percolation rate, sediment density in agriculture land use is more than other land uses.
