rate of groundwater flow

In this paper the two-dimensional unsteady groundwater flow toward the drain system has been studied, and formulas derived for computing the groundwater table and its time rate of change due to the combined effect of groundwater evaporation, rainfall or irrigating infiltration and artesian water leakage.

本文研究了流入排水系统的地下水二元不稳定流动，并导得了在地下水蒸发、降雨或灌溉入渗、承压水渗漏等综合作用下，地下水面位置及其上升、下降速度随时间变化的计算公式。
