设计水库时必须知道: (一)水库建成後,各个时期地下水的壅水高程和浸没沿岸地区各低窪地段的可能性; (二)水库建成後各个时期内浸湿两岸的渗失量以及水库渗漏时期的久暂; 为了研究地下水的规律和解决这些问题,必须研 When designing reservoirs, it is necessary to know: (i) the elevation of the sludges of groundwater and the possibility of submerging the low-lying areas along the coastal areas after the completion of the reservoir; (ii) the amount of water loss on both sides of the dam and the reservoir seepage during various periods after the completion of the reservoir Leakage of a long time; in order to study the laws of groundwater and solve these problems, we must research
