In a tidal cycle , waglan island is typically the first to experience the high low tide while tsim bei tsui is generally the last 在一個潮汐周期內(nèi),通常漲潮和退潮會首先在橫瀾島出現(xiàn),而尖鼻咀則比較遲。

A river quality management model is proposed for the optimal waste load allocation in a tidal river basin , taking into account the impacts of stochastic pollutant discharge and dynamic hydrological conditions on water quality during a tidal cycle 摘要考慮污染源強隨機變化和感潮河流潮周期內(nèi)動態(tài)水文條件對水質(zhì)的影響,建立了優(yōu)化污染負荷分配的流域水質(zhì)管理模型。
1 - d and 2 - d model for non - uniform bedload transport are applied to compute the amount of bedload in the south branch of the changjiang estuary . it can be found that the peak value of bedload transport in a tidal cycle , computed by 2 - d model , is obviously larger than that computed by 1 - d model , which is induced by the disequilibrium of bedload transport in cross - river direction 在此基礎上,將非均勻推移質(zhì)公式推廣到二維計算,并與一維計算結(jié)果作了對比,發(fā)現(xiàn)兩種計算所獲得的凈輸沙量相差不大,但二維輸沙過程線峰值較一維計算要大,這正是河道內(nèi)推移質(zhì)運動橫向不均勻性的體現(xiàn)。
