Methods for solving problems of multidimensional, partially saturated steady flow in soils

Abstract

A computer program for solving steady-state Darcian transport of fluid in heterogeneous, partially saturated, porous mediums is described. The program is capable of handling one, two, and three-dimensional and axisymmetrical problems with up to 8000 grid points. Instability of the equations and its control are discussed. Solutions of typical problems that are important in industrial waste disposal, irrigation, and drainage are presented. (auth)
