Finally , in orthogonal curvilinear coordinate systems numerical model is established and applied in the yangtze river estuary in which some regulation plans are taken include submerged jets and groins . verifications are also done to verify water level and velocity . flow fields are computed for the analysis of effect of regulation engineering on the whole water area 最后,應(yīng)用正交曲線網(wǎng)格技術(shù),建立了正交曲線坐標(biāo)系下廣義淺水方程的計(jì)算模式,將之應(yīng)用于長(zhǎng)江口深水航道整治工程的流場(chǎng)計(jì)算,進(jìn)行實(shí)測(cè)水位、流速驗(yàn)證和流場(chǎng)模擬。
