Approaches to modeling soil erosion caused by water: A review

One of the most serious problems is soil erosion serious global environmental problem that is affected by several factors, including natural and human. Over the years, various models have been developed to simulate the prediction of estimating soil erosion and sediment yields under a wide range of conditions. The application of these models generally depends on the type of soil and climate in a particular area because the models differ in complexity and input requirements. In this paper, we review almost all models used in estimating soil erosion and its applications, in addition to a comprehensive and detailed review of all studies conducted during the past two decades to predict soil erosion and estimate the amount of sediment generated by it.
