Abstract An analytical and experimental investigation of a matching method for the determination of the parameters in the Brooks-Corey K(h) and h(theta) relationships is presented. The method is based upon fitting an analytically derived response function to the corresponding measured one for one-dimensional redistribution of water injected into the soil. Comparisons of the parameter values derived by the matching method with those obtained in independent experiments on six soils ranging from clay to sand are made. The parameters were satisfactorily estimated in most cases.
