Soil erosion is a big problem that can harm the environment. Scientists have studied different models to predict soil erosion. They found that the Universal Soil Loss Equation (USLE) is commonly used because it is simple and works well with different factors. However, one challenge is that there is not always enough data to check if the models are accurate. Some researchers suggest using other factors like land cover and management to validate the models. Overall, there is still uncertainty about which soil erosion prediction model is best to use.
