Experimental Study on Changes of Artificial Vegetation Distribution on Flow and Sediment Movement of Overland Flow
摘要
Abstract
With the influence of different distribution of artificial vegetation,the characteristics of overland flow and the corresponding sedi-ment transport were herein investigated experimentally. The experimental vegetation model was made by the PVC pipe and the experimental distribution of artificial vegetation consisted of uniform and non-uniform modes. The results show that the characteristics of overland flow are significantly affected by the different vegetation distributions. When there is deposition on the overland,the non-uniform modes have higher effect on the characteristics of overland flow than that of uniform modes,but the effect is very little without the deposition. Similarly the sedi-ment transport rate depends on the changes of flow and vegetation distribution with the action of sediment deposition.关键词
