一、引言给水度是潜水含水层的重要水文地质参数,是农田排水设计、浅层地下水资源评价以及地下水非稳定流计算的基本依据。为了进一步探求给水度的变化规律,我们对细砂在不同的等速下降及不同地下水位埋深条件
I. INTRODUCTION Water supply is an important hydrogeological parameter of submerged aquifer and is the basic basis for farmland drainage design, evaluation of shallow groundwater resources and unsteady groundwater flow calculation. In order to further explore the changing law of water supply, we have different rates of fine sand at different groundwater depth and buried conditions
