由于河床下切,东江下游及三角洲河段枯水期低潮位逐年降低,导致一些水利设施不能正常运行。为了保障东莞市东江与水库联网供水水源一期工程能正常取水,对河床下切造成黄大仙取水口的水位变化情况进行研究,为工程设计提供依据。

As a result of riverbed cutting, the low tide level in the lower reaches of the Dongjiang River and the delta reaches decreases year by year, resulting in the failure of some water conservancy facilities to operate normally. In order to protect the first phase of Dongjiang and reservoir network water supply project in Dongguan City, water can be properly taken into account, the change of the water level of Huang Daxian intake caused by riverbed undercutting is studied, which provides basis for engineering design.
