Though the water levels cross one section are almost equal, the velocities differ greatly. at the some cross - section, the velocity in the in the quirk may be double as that on the floodplain. the water surface will rise hi the southern branch because of the improper diffluence ratio, if using the designed diffluence col
淮河入海水道河口段水位值橫向分佈相差無幾，而流速的橫向變化較大，泓灘平均流速差最大可達一倍以上，在現有的分流口設計條件下，若按設計的南北汊分流比，南分流口有壅水現象發生，如果南汊分流增大到800m ~ 3 / s左右時，則水流較為通暢。A 2 - d hydrodynamic - numerical model was applied to typical rocky rapids called jiyutan by comparing different computational models. based on the comparison of different schemes, the change of the discharge and the flow current in a branch were analyzed, and the relationship between the flow condition and excavation area, scope as well as mode was discussed, the conclusions show : ( 1 ) in a branching rocky rapids, the velocity may be reduced and flow condition can be improved by excavating one channel partly
本文在對各種數學模型比較的基礎上，應用二維水動力數學模型研究典型石質汊流灘? ?廣西潯江鯽魚灘航道整治工程方案，通過各方案計算結果比較，分析了不同汊道的開挖及汊道內不同開挖面積、開挖范圍以及開挖方式所引起的分流比及工程區域航道水力條件的變化規律，研究結果表明： （ 1 ）對于石質汊流灘來說，在某一汊道通過局部開挖河槽，擴大過水斷面面積，可以達到降低工程段流速、改善局部水流條件的目的。We struck our bargain on the spot. in three minutes i had the hispaniola sailing easily before the wind along the coast of treasure island, with good hopes of turning the northern point ere noon, and beating down again as far as north inlet before high water, when we might beach her safely, and wait till the subsiding tide permitted us to land
