| Abstract: | The author studied the effects of slope gradient of land surface, vegetation coverpercentage, rainfall intensity upon infiltration rate into soil under the conditionsof artificial rainfall with high intensity. The results showed that the accumulatedinfiltration water was in inverse proportion to slope gradient, and also, there exist-ed an apparent critical slope gradient affectimg the depth of accumulated runoffwater. In the case of this test, the critical slope gradient of different time sectionsand different vegetation, types varied between 23.6°-30.4°. The vegetation coverpercentage increased, and the accumulated infiltration water went up exponentiallyThe steady infiltration rate has an increasent trend with the increasing rain intenasity. |
