摘要：
The model shows that the number of holes per unit soil area, as well as the diameter and depth of the holes, greatly influence infiltration and surface runoff. The assumption of noncapillary flow through continuous holes or cracks may be used to explain some of the observed deviations from capillary flow theory and the fast movement of surface-applied agricultural chemicals through the soil profile. -from Authors
