In the meantime the time variation of the water level in the ditch has been taken into account, therefore the groundwater head are time-varying as the groundwater flows toward the drain system.

在讨论这个问题时，又考虑进了排水沟中的水位也是随时间而变化的，因此在地下水流动过程中的任一瞬时，其地下水头差也是一个变量。

The results show that the response of well water level to pressure variation in well air has relation to the period of pressure variation.

试验结果表明，井水位对井口空气压力变化的响应与变化周期有关。

The distributing trend of soil moisture contour map in under soil is rising up from bottom to surface, which indicates that ground water level has no influence on soil moisture variation.

下部土壤含水率等值线分布由底部向上都呈递增趋势，表明本次试验土壤水分动态变化不受地下水位的影响。
