Soil erosion is a big problem caused by nature and people. Scientists use models to predict how much soil will erode in different places. They reviewed many models and found that some are used more often, like USLE, RUSLE, and WEPP. These models help estimate soil loss, sediment, and other erosion factors. Most models focus on erosion on farms and in watersheds. Scientists suggest expanding models to include gully erosion and developing simpler models based on rainfall and soil properties. They also recommend using local knowledge to manage soil erosion.
