Using flow sediment laden formula set by Hanqiwei and overyear runoff,sediment data,the sediment retaining prediction of Manwan reservoir is carried out.

利用韩其[1]水流挟沙力公式以及戛旧站多年流、泥沙,行了漫湾水库的拦沙预测分析。

It is found that the natural runoffs in these two stations have the same crytic period analysis period of 42.7 years.

并在此基础上，通过计算判定得到两个水文站的天然流序列都存在42.7年隐含周期。

In the east, the water is mainly oceanic with relatively minor dilution from direct monsoonal rainfall and runoff from small streams.

东部水域主要海水，而直接的季候雨及小溪溢流，把海水稍冲淡。
