Comparison of runoff generation,sediment yield and hydrodynamic parameters on the undisturbed and the disturbed land surface in the Shenfu-Dongsheng coalfield
The disturbed land of the exploitation in the shenfu-dongshen coalfield destroyed the ground vegetation cover and the soil structure,caused serious soil erosion.The changing discipline of the runoff generation,sediment yield and the hydrodynamic parameters of the disturbed land have been analyzed.The result indicated: the runoff generation time of the disturbed land was less than that of the undisturbed land;the intensity of runoff yield,the initial sediment yield and the intensity of the sediment yield of ...
