Abstract

We deduced a simple evaluation method of infiltration parameters in a watershed as follows. (1) S and K of Philip's equation are determined by using a double ring infiltrometer experimentally. (2) Philip's equation is changed for Green-Ampt's one by mathematical equivalent and their parameters are transposed each other. (3) Campbell's empirical equation is deduced from the capillary theory and their parameters are also expressed by the infiltration ones. (4) Some infiltration parameters are correlated experimentally. (5) All the infiltration parameters are deduced from the above relationship and the experimental result of the double ring infitrometer in a watershed.
