| Abstract: | Factors necessary for analysis in prediction of soil erosion in development and construction projects are as follows: original amount of soil loss and permissible soil loss, factors causing soil loss, patterns and ways of soil loss, factors of soil loss in construction projects and identification of soil loss regions, prediction period, and possible soil loss. USLE can be used in prediction of soil loss by water erosion. Therefore,model of USLE,comparison of adjacent projects, comparison of erosion intensity before and after project construction and typical case investigation and estimation are basic methods. |
