| Abstract: | It establishes the sediment yield prediction model of partial least-squares coupled with artificial neural network by using nine factors from the process of precipitation for studying the laws between rainfall and erosion and sediment yield of small watersheds in the southwest of Henan,fully utilizing the advantages of partial least-squares regression and artificial neural network. The outcomes show that it supplies higher precision,speedy and convenient calculation service in prediction of erosion and sedi... |
