指流间距对模拟指流水分运动的影响
|
摘要
为了解指流间距对模拟指流水分运动的影响,通过模拟不同的指流间距,研究不同间距对指流水分运动的影响。结果表明,指流间距越大,指流域中的水分入渗越快,且指流流速与指流间距呈线性关系。
In order to understand the influence of finger flow spacing on simulation finger flow water movement,by simulating different finger spacing the effect of different spacing on finger flow water movement was observed.The results showed that the larger the finger-flow spacing was,the faster the water infiltration was,and the relationship between the finger-flow velocity and finger-flow spacing was linear.
