水沙耦合模型在小流域水土流失研究中的应用OA

Taking a small watershed in southern Liaoning province as an example,this paper deeply explores the change rule of soil and water loss in a small watershed,builds a water-sediment coupling model to predict soil erosion in a small watershed,and uses detailed measured data to comprehensively and rigorously verify the constructed model.The results show that compared with the single sediment production model,the water-sediment coupling model can comprehensively consider the factors of rainfall erosion and slope sediment production,and significantly improve the prediction accuracy of soil and water loss.The research results provide important reference for small watershed management design.
