| Abstract: | Five fixed slope experimental channel and artificial rainfall system are used to simulate slope flow under the different slope and rainfall intensity.The variation law of hydrodynamic properties of the overland flow with rain intensity and slope is analyzed.The experimental data is provided for study on the slope erosion theory.The result indicates that the hydrodynamic properties of the overland flow are good function relationship between flume slope and rainfall intensity under condition of artificial rai... |
