非饱和土壤水流问题的广义迎风差分法
A Generalized Upwind Difference Method for Unsaturated Soil Water Flow Problems
【摘要】 利用广义迎风差分法建立一维非饱和水流问题的数值模型,并给出误差估计。数值结果表明,该格式对求解非饱和水流问题具有可行性。
【Abstract】 In this paper,a generalized upwind difference method for one-dimensional unsaturated soil water flow problems is presented,and the error estimate is given to identify the accuracy of the method.The numerical results indicate that our method is feasible for unsaturated soil water flow problems.
