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]流挟沙力公式以及戛旧站多年径流、泥沙资料,进行了漫湾库的拦沙预测分析。

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，过计算判定得到两个文站的天然径流序列都存在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.

东部域主要海，而直接的季候及小溪溢流，把海稍冲淡。
