【摘要】：建立了甬江河道及口外海域平面二維潮流泥沙數(shù)學(xué)模型,對(duì)2015年6月半個(gè)月的潮流場(chǎng)和懸沙場(chǎng)進(jìn)行模擬,模擬結(jié)果與實(shí)測(cè)資料吻合良好。計(jì)算得到了研究區(qū)域洪季的余流場(chǎng)和輸沙格局,結(jié)果表明:甬江口外余流整體由西北指向東南,河道余流指向下游;除口門局部水域,甬江口外輸沙格局基本與余流場(chǎng)一致,懸沙經(jīng)漲潮流的作用被帶入甬江河道,致使河道內(nèi)近口門處的輸沙格局由口門向內(nèi);甬江口局部區(qū)域輸沙格局與余流場(chǎng)存在差異的原因是懸沙輸移與潮流運(yùn)動(dòng)存在時(shí)間上的滯后。
[Abstract]:A two-dimensional tidal current and sediment mathematical model for the Yongjiang River and its offshore waters is established. The tidal current field and suspended battlefield in June 2015 are simulated. The simulation results are in good agreement with the measured data.The residual flow field and sediment transport pattern in the study area during the flood season are calculated. The results show that the residual current outside the Yongjiang Estuary is from northwest to southeast, the residual current of the channel is pointing downstream, and the pattern of sediment transport outside the Yongjiang Estuary is basically consistent with that of the residual current field except in the local waters of the estuary.The action of suspended sediment through rising tidal current is brought into the channel of Yongjiang River, resulting in the pattern of sediment transport from the entrance to the inside of the channel near the entrance;The reason for the difference between the sediment transport pattern and the residual flow field is the lag between suspended sediment transport and tidal current movement.
