水位降深 meaning in English
drawdown level
Examples
- The new apparatus not only can reflect the visual change of water level , the influence of water level and its decrease depth on the specific water yield , but also can be operated and understood easily by students
新设计的给水度实验仪能直观地显示出地下水水位的变化，并能反映出初始地下水水位埋深及水位降深对给水度的影响，且操作简单，易于学生理解掌握。 - ( 4 ) the maximum water quantity becomes greater , the better is the filtering bed permeability , the higher the river hydraulic conductance , the higher the river level , the larger the water - collecting area and the bigger the distance between collecting pipes . the water quantity varies directly with drawdown
( 4 )滤床的渗透性能越好，河床水力传导系数越高，河水水位越高，取水面积越大，取水管之间的间距越大，则最大取水量越大；水位降深与取水量成正比关系。 - This procedure can imitate the single well pumps water the chronometer calculates at all point water level in district declines deep with horary variety ; study the sport law of the rivers ; solve definitely flow draw water issue wanton boundary the wells of termses , predict that dives under water in the location , guide and construct and excavate the progress , appraise the rationality of the precipitation scheme
此程序可以模拟单井抽水时计算区域各点水位降深随时间的变化，研究水流运动规律；求解任意边界条件下的井定流量抽水问题，预测潜水位，指导施工开挖进度，评价降水方案的合理性。
