Hong kong s two largest reservoirs , high island and plover cove held 507 million cubic metres . a particularly high rainfall of 本港两大水塘万宜水库和船湾淡水湖,总存水量合共5
At the end of 1998 , 568 million cubic metres of water were in storage , compared with 485 million cubic metres at the end of 1997 年底的总存水量为5 . 68亿立方米,一九九七年底则为4 . 85亿立方米。
At the end of 2002 , 442 million cubic metres of water were in storage , compared with 444 million cubic metres at the end of 2001 截至二零零二年年底的总存水量为4 . 42亿立方米,二零零一年年底则为4 . 44亿立方米。
At the end of 2000 , 480 million cubic metres of water were in storage , compared with 501 million cubic metres at the end of 1999 截至二零零零年年底的总存水量为4 . 80亿立方米,一九九九年年底则为5 . 01亿立方米。
In 1959 , with the completion of the tai lam chung reservoir , hong kong s total storage capacity rose to 10 billion gallons . on average every person would have a daily supply of 9 . 1 gallons 1959年大榄涌水塘建成后,全港的存水量提升到100亿加仑,平均每人每日供水量约为9
Taken into account the character of water cut and other factors such as the difference between injected steam and prouced water , a comprehensive discriminance to judge underground water is put forward 在此基础上,结合存水量变化等参数,提出了一种综合判断地层水侵入规律的方法。
The upper reservoir had a concrete dam 400 ft . long and 138 ft . high with a storage of 175 , 000 , 000 gallons . the dam of the lower reservoir was modified and reconstructed from that of the former tai shing paper manufacturing co . 建成后分上、下两个水塘,上塘是用混凝土筑堤坝,坝长400尺,高138尺,存水量为1
