| Abstract: |
| 【Objective】Sediment deposition in the lower reaches of the Yellow River is one of the key problems restricting the sustainable development of irrigation areas from the Yellow River. Xiaokaihe irrigation area has scientifically solved the problem of sediment deposition from the Yellow River by gravity long-distance sediment transport technology. However, in recent years, under the influence of global climate change and human activities, the water and sediment of the Yellow River have changed significantly. It is urgent to clarify the characteristics of water diversion and sediment diversion in Xiaokaihe irrigation area and the law of sediment erosion and deposition in sedimentation basin under the changing environment, so as to support the ecological protection and high-quality development of the Yellow River Basin. 【Method】Based on the data of Xiaokaihe irrigation area from 1999 to 2015, this study systematically analyzes the variation law of water and sediment in Xiaokaihe irrigation area from four aspects: water delivery volume, sediment transport volume, sediment distribution law of sediment transport channel and sedimentation basin after water and sediment regulation of the Yellow River. 【Result】 It is found that the water conveyance, water and sediment in the irrigation area generally show a downward trend, and the sediment deposition gradually changes from the branch channel to the sediment transport channel and sedimentation basin. .【Conclusion】It is urgent to carry out the research on a new sedimentation basin that takes into account sediment deposition and ecological protection. |
