中文摘要 |
目前,長江中下游河勢已基本穩定,長江中游汊道的沖淤表現出「流量決定沖淤性質,沙量決定沖淤幅度」的規律。以長江中游汊道的研究方法為基礎,通過實測資料分析,對長江下游大通-江陰感潮段汊道的沖淤規律進行了研究。結果表明,長江中游汊道的沖淤規律對於長江下游大通-江陰感潮段同樣適用。結合未來水沙條件的變化,對大通-江陰感潮段汊道的沖淤趨勢進行了預測。 |
英文摘要 |
The general regime of the middle-lower Yangtze River has been stable currently, and the law of erosion and deposition in braided reaches in the middle Yangtze River manifests as "water discharge decides transformations between erosion and deposition, and sediment concentration decides degrees of erosion and deposition". On the basis of the research methods in braided reaches in the middle Yangtze River and the analysis of field data, the law of erosion and deposition in braided and tide-affected reaches between Datong and Jiangyin in the lower Yangtze River is studied. The results show that the aforementioned law of erosion and deposition in the middle Yangtze River is applicable to the braided reaches between Datong and Jiangyin. Accordingly, the trends of erosion and deposition in braided reaches between Datong and Jiangyin are predicted based on the future variations in water and sediment discharges. |
