摘要
本文建立了一个非饱和土壤水一维流动的数值计算模型，用以模拟均质土壤、地下水位埋深较深，且在不同的初始条件与边界条件下的水分运动。此模型通过有限差分法模拟了降雨或灌溉水人渗、降雨或灌溉水以后土壤水分在剖面上的重新分配情况。程序用ＴＲＵＢＡＳＩＣ语言编写，在ＷＹＳＥ—３８６计算机上实现，并经Ｗａｒｒｉｃｋ试验验证。
A numerical model of one-dimensional flow through unoaturated homogeneous soil has been developed to simulated the water movement in soil with a deep groundwater table under the initial and boundary conditions.This model has simulated redistribution of infiltration and soil-water due to precipitation and irrigation at the profile by finite different method.The modelling experiment programmed with TRUBASIC has been carried out on a computer WYSE-386 and verified by warrick laboratory tests.
