黄河口尾闾河道萎缩过程与水沙条件的关系

Relationship between Atrophy Process of Tail Channel and Sediment in Yellow River Estuary

采用实测资料分析和理论探讨相结合的方法,揭示了黄河口尾闾河道萎缩过程,探索了河道萎缩与水沙条件的响应关系。结果表明,尾闾河道萎缩过程与水沙条件有着良好的响应关系,小浪底水库实施调水调沙明显改善了水沙条件,河道萎缩有所恢复,为科学治理黄河口提供了技术支撑。

The atrophy process of tail channel in the Yellow River estuary is revealed and the response relationship between atrophy of tail channel and sediment are explored by using combination method of observed data and theoretical analysis.The results show that the response relationship between atrophy of tail channel and sediment is good;the regulation of flow and sediment of Xiaolangdi Reservoir ameliorates the condition of flow and sediment of the Yellow River estuary;the atrophy of tail channel recovers in a certain extent.Thus,it provides the technical support for harnessing the Yellow River estuary.
