【摘要】：赣江尾闾主支河道枯期水位屡创新低,对水资源利用、通航、水景观水环境等都将产生不利影响,并且未来赣江尾闾河段的枯季水位仍然存在逐渐降低的趋势。通过分析主支河道近年来的水沙特性,建立平面二维水流泥沙数学模型,选取了1992、2002、2004年的水沙资料对该河段进行数值模拟研究。对比分析整治工程实施前后该河段的河床冲淤、洪枯水位、航道水深变化以及边滩利用情况,证明主支河道整治工程能有效调控河道枯季水位、保障航道通航水深、改善水景观、提高洲滩利用率,从而促进当地的水运经济发展。
[Abstract]:Based on the analysis of the characteristics of water and sediment in the main branch river in recent years, a plane two-dimensional flow and sediment mathematical model was established, and the sediment data of 1992 ~ 2002 and 2004 were selected to carry out a numerical simulation study of the reach.Comparing and analyzing the river bed scouring and siltation, flood and dry water level, channel water depth change and beach utilization before and after the implementation of the regulation project, it is proved that the main branch river regulation project can effectively regulate the river channel water level in the dry season and ensure the navigable water depth of the channel.Improve water landscape, improve beach utilization rate, thus promoting the development of local water transport economy.
