| 摘 要： | 应用改进的三维数值模式,研究了长江河口北支倒灌盐通量.当径流量取11 000 m3/s,风况取风速为6 m/s的北风时,长江河口北支上段大潮、中潮、小潮和半月平均盐通量分别为-26.28,-14.65,-1.58和-15.83 t/s,发生北支盐分倒灌进入南支,大潮期间的盐分倒灌量远大于小潮期间.通过数值计算定量分析了...

| Abstract: | The salt flux from the North Branch into the South Branch in Changjiang River Estuary was studied with the improved 3-D numerical model.In case of 11 000 m3/s river runoff and 6 m/s north wind,the net salt fluxes at the upper reaches of the North Branch during spring,moderate and neap tides and the half month averaged are-26.28,-14.65,-1.58 and-15.83 t/s respectively,which means that the net salt flux is from the North Branch into the South Branch,and this salt flux downdraught is much greater during spring... |
