The computed results show that the flow field in the estuary changes significantly due to the project
數值模擬結果表明長江口攔門沙深水航道工程對長江口水域的流場有明顯的影響。Based on the depth - integrated 2 - dimensional mathematical model, the numerical simulation of the effect of a deep - water navigation channel project on the hydrodynamic flows is presented in this paper
本文基於沿水深積分的平面二維非定常流動數學模型對長江口攔門沙水深水航道工程對長江口水域流場的影響作了細致的數值模擬。Based on the back silting analyses of the sandbar - dotted waterway in the oujiang river estuary after three times dredging, reasons for back silting in the waterway are presented considering influences of flow dynamics, waves and salinity distribution on sediment concentration
摘要通過對甌江口攔門沙航道3次疏浚后的回淤分析，以及從甌江口的水流動力條件、風浪、鹽度分佈對含沙量影響等的初步分析，得出了攔門沙航道回淤的原因。Based on the analysis of satellite images of various periods, landform data and river channel transverse section evolution in the lower yellow river, the characteristics of the river channel boundary condition changes at different location are clarified as middle flood channel flood transport width and area are evidently decreased especially for the main channel with comparison to 1950s, beach area that is unimpeded before become blocked because of road, irrigation channel constructed on it, and consequently intensify high edge of beach and lowering dyke and river
在現場查勘的基礎上，通過對丹江口水庫和小浪底水庫攔沙初期下遊河道演變、排洪能力變化特點的對比，分析了黃河下游防洪面臨的新形勢:小浪底水庫攔沙初期，下遊河道發生沖刷，但艾山以下窄河段沖淤變化不大，近年來形成的淤積萎縮的狀況難以很快改觀，游蕩性河段調整劇烈，工程出險機遇增大，河道水位流量關系中水流量以下部分同流量水位明顯降低，中水流量以上部分水位降低幅度可能會明顯偏小，防洪形勢仍不容樂觀。Transportation laws of salinity with flow in the lanmensha area of the yangtze river estuary are discussed
