Numerical simulation of vertical one-dimensional water movement in unsaturated soil: A case study on coniferous forest brown soil on northern slope of Changbai Mountains
一维垂向非饱和土壤水分运动的数值模拟——以长白山北坡山地棕色针叶林土为例

This paper established a mathematical model to simulate the vertical one-dimensional flow processes in unsaturated zone,based on the basic equation of soil water movement and the actual layer structure of coniferous forest brown soil on northern slope of Changbai Mountains.The numerical discrete equations of this model were derived,and the procedure for the numerical simulation of the model was programmed.This model was validated with numerical simulation,and the simulation values were consistent well with the measurements.
