| Abstract: | The water-wind erosion crisscross region on the Loess Plateau is the main source of the coarse sediments of the Yellow River,where eco-environment is very fragile.The baseflow is of great significance to maintain sustainable development of the river ecosystem in this region.In order to test the applicability of automated baseflow separation methods on the water-wind erosion crisscross region on the Loess Plateau,several commonly and widely used methods including minimum smoothing method,HYSEP and recursive ... |
