黄河口清水沟流路汊河方案研究

通过对清水沟流路的北汊、清8汊及原河道各个组合方案的行河年限、对下游河道淤积反馈的影响、行河费用、防洪效果及对孤东油田防潮堤安全的影响等方面进行研究,认为清水沟流路的行河寿命还有50年以上.同时.建议清水沟流路行河次序为:清8汊河行河至西河口以下65 km左右时改走北汊,北汊行河至改汊最终控制条件时改走原河道,原河道行河至改汊最终控制条件时改走清8汊河,清8汊河行河至改汊最终控制条件时改走备用入海流路.

Study on an Anabranch Plan of Qingshuigou Flow Path of the Yellow River Estuary

It studies the service life of flowing, influence to the feedback of deposition of the lower channel, flowing cost, effect of flood control and influence to the security of tidal barrier of Gudong Oil Field of each integrated plan of Bei anabranch, Qingba anabranch and the original channel of Qingshuigou flow path and deems that the service life of Qingshuigou flow path is still more than 50 years. In the mean- time, it suggests the flowing order of Qingshuigou flow path as follows:the Qingba anabranch changes its course to Bei anabranch at about 65 km downstream Xihekou, Bei anabranch changes its course to the original channel at Gai anabranch of final control condition, the original channel changes its course to Qingba anabranch at Gai anabranch of final control condition and Qingba anabranch changes its course to the re- served flow path to the sea at Gai anabranch of final control condition.
