INFILTRATION INTO UNSATURATED MOIST SOIL

摘要

Infiltration into unsaturated moist soil is affected by the soil moisture content as well as the properties of soil and infiltration water. In this paper, one dimensional infiltration equation is solved assuming that the soil is the ideal soil and the vertical distribution of moisture content can be expressed by an approximate form of Smith's theory. The solution may be useful to evaluate the effect of physical factors of the system on the infiltration capacity and the total infiltration.
