黄河为世界有名的多沙河流.其河口喷沙、尾闾段迁徙改道以及三角洲的淤积延伸,对两侧中小河流河口段的冲淤变化,具有十分显著的影响,给这些河口治理和开发利用带来了许多复杂问题.本文主要是根据历年实测和调查资料,对黄河口两侧中小河流河口段的冲淤变化规律及其与黄河河口泥沙的关系,进行了初步分析. The Yellow River is a world-famous multi-channel river and its estuary sandblasting, migration and diversion of the tail section and siltation of the delta have a very significant impact on the erosion and deposition of the estuary sections of the middle and small rivers on both sides, so as to harness and exploit these estuaries Brings many complex problems.This paper mainly analyzes the variation law of erosion and siltation at the estuary of the middle and small rivers on both sides of the Yellow River mouth and its relationship with the sediment of the Yellow River estuary based on the measured and surveyed data over the years.
