Changes in Sediment Concentration on Grassland Slope with Optimized
The artificial simulated rainfall test method is used to deeply analyze
the mechanism of the change of sediment concentration on the grassland
slope .Under the experimental condition, the results show the following.
1). The addition of root volume can increase the accuracy of the
expression of the sediment concentration variability and reduction of
sediment concentration by 0.5% and 1.12%, respectively; 2).The
relationship between the vegetation characteristics and the sediment
concentration on the grassland slope is best expressed by the coverage
and root volume; 3).The slope plays a larger role than the rain
intensity in the change of sediment concentration on grassland slopes .
