摘要
A finite element method is described for the solution of the Richards' equation governing the groundwater flow in variably saturated porous media. The dependent variable, the pressure head, is approximated over each isoparameteric element using mixed linear, quadratic, and cubic base functions. This approximation reduces the problem to a set of matrix equations whose term associated with the temporal derivative is the mass matrix.-from US Govt Reports Announcements, 26, 1980
