| 摘 要： | 利用适合于黄河下游河道和黄河口水域的一、二维连接泥沙数学模型，计算研究了黄河口演变、入海流路的淤积延伸对下游尾闾河道的反馈影响。通过比较考虑和不考虑入海流路淤积延伸2种情况的计算水位和淤积量的变化得出：单一的河口延伸对下游河道淤积的影响过程是一个相对较长的过程，需要几年、甚至十几年的发展，影响程度自下游到上游逐渐减弱。

| Abstract: | An integrated 1-D and 2-D sediment transport model is used herein to study the response of the revolution of Yellow River Mouth on its trail channel, By computing the water level and sedimentation processes with and without considering the extension of flow path, the results show that the effect of the river mouth path extension on the sedimentation of the trail channel is a longer period of evolution for several years or even over 10 years, and furthermore, the effect becomes weaker and weaker gradually from downstream to upstream in general. |
