黄河口汊1—汊2河段河势演变分析及治理

Analysis and Management on River Regime Evolution of No.1-No.2 By-Pass Section of the Yellow River Estuary

对黄河口汊1—汊2河段河势演变情况进行了分析,认为该河段冲淤变化较大,特别是2002年调水调沙以来河势演变明显,河道冲刷塌岸严重,对孤东浮桥及北顺河路构成威胁,改汊点弯道仍向右岸逐步发展。建议应尽快分析研究河势发展趋势,及时采取工程措施加以防护。

It analyzes the river regime evolution of No.1-No.2 by-pass section of the Yellow River estuary and considers that the variation of scour and fill of this section is greater,especially since the regulated discharge regime of the river conducted in 2002,channel scour and bank collapse are serious,threatening the Gudong Floating Bridge and Beishunhe Road and the trained bend still developing towards the right bank.It suggests studying and analyzing the development trend of river regime as soon as possible and adopting engineering measures for protection.
