【摘要】：贛江尾閭主支河道枯期水位屢創(chuàng)新低,對水資源利用、通航、水景觀水環(huán)境等都將產(chǎn)生不利影響,并且未來贛江尾閭河段的枯季水位仍然存在逐漸降低的趨勢。通過分析主支河道近年來的水沙特性,建立平面二維水流泥沙數(shù)學模型,選取了1992、2002、2004年的水沙資料對該河段進行數(shù)值模擬研究。對比分析整治工程實施前后該河段的河床沖淤、洪枯水位、航道水深變化以及邊灘利用情況,證明主支河道整治工程能有效調(diào)控河道枯季水位、保障航道通航水深、改善水景觀、提高洲灘利用率,從而促進當?shù)氐乃\經(jīng)濟發(fā)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.
