建立了一维垂直非饱和土壤水分运动的数学模型,并采用有限差分方法对模型进行数值求解,模拟了不同降雨强度条件下水分分布的动态规律,数值模拟结果表明:降雨强度的大小直接影响着土壤水分湿润锋的分布,并且所建立的模型与实验测试结果吻合较好,验证了模型的可靠性,从而可为定量化研究填埋气体和浸出液释放提供理论根据。
3.
The accumulated infiltration and wetting front in different infiltration heads were studied by horizontal column in this paper.
通过对不同入渗水头下的土壤累积入渗量及湿润锋进行分析,得出了累积入渗量与不同入渗水头以及湿润锋与不同入渗水头之间的变化规律,即随着入渗水头的增加,其累积入渗量和湿润锋在整体上有增加的趋势,但其增加的趋势并非像恒定水头时的土壤累积入渗量那样呈乘幂分布,而是具有一定的阶梯性,呈阶梯形增加。
2) wetted front
湿润锋
1.
A series of experiments about the effect of dripper discharge,amount of applied water and dripper distance on soil wetted front had been researched under interference.
通过模拟试验,研究了不同滴头流量、灌水量和滴头间距下双点源滴灌水分交汇作用对湿润锋运动规律的影响,结果表明:在交汇界面,湿润锋水平和垂直入渗距离与入渗时间符合多项式关系,在未发生交汇的平面符合幂函数关系。
