SELF-DISCRETE FINITE VOLUME ELEMENT SIMULATION FOR TWO-DIMENSION UNSATURATED SOIL WATER FLOW PROBLEM
二维非饱和土壤水分运动问题的半离散有限体积元模拟

A numerical model for a two-dimension unsaturated soil water flow equation is established with a finite volume element method.The existence and uniqueness of its discrete finite volume element solutions are proved,and the error estimates of the discrete finite volume element solutions are analyzed.And finally,a numerical example is given.Moreover, it is also shown by numerical example that the finite volume element method to solve two-dimensional unsaturated soil water problem is reliable,stable and practic...
