河水入渗过程中蒸发损失的实验模拟研究

Simulation Study on Experiment of Evaporation Loss in the Process of Infiltration of River Water

为了深化河流入渗机理的认识以及提高地下水资源评价的精度,本文就河水入渗过程中蒸发损失量的计算进行了室内模拟试验研究。试验结果表明,常年有水河流的河水入渗量的蒸发损失率小于10%,即有90%以上的河水入渗量补给地下水。

To deepen the knowledge of river infiltration mechanism and improve the precision of groundwater resources evaluation, the article carries on simulation study for calculating the quantity of evaporation loss in the process of river water infiltration. The results show its evaporation loss rate is usually less than 10% for permennial river. It means there is above 90% river water infiltration will be replenished to groundwater.
