黄河口入海流路摆动改道与治理稳定

Evolution and treatment on swing and change of path-to-sea of the Yellow River estuary

黄河口受上游来水来沙和海洋动力条件的综合影响,河道淤积延长、摆动改道极其剧烈复杂。本文概述了近代黄河口入海流路的演变,阐明了清水沟流路使用年限较长的原因与此期间的来水来沙条件、人工治理以及工程防御洪水的强度和入海口门处的海洋动力增强等因素有关：展望了清水沟流路的行河年限。

Due to combined influence of water and sediments from upstream and oceanic hydraulic conditions, the estuary of the Yellow River features in extended filling-up of the river course and dramatic and complicated swing and change of the river course. The paper summarizes evolution of path-to-sea of the Yellow River estuary in recent years and demonstrates that the long duration of clean water path is related to factors of water and sediment conditions, human treatment, extent of flood tolerance of structures and increase of oceanic dynamics at the sea inlet, etc. The Duration of clean water path is also projected.
