摘要：

The parameter n in the well-known expression for hydraulic conductivity K = K0Sen (where K-0 is its value at satiation and S-e the effective saturation) is determined as a function of the exponent in the power form of the soil-water retention relationship. The result is validated with an extensive experimental database comprising some 43 soils, collected by Mualem. (C) 2000 Elsevier Science Ltd. All rights reserved.
