【摘要】：本文建立曲線坐標系下的雙曲型緩坡方程波浪模型和考慮波浪輻射應(yīng)力影響的深度平均2D潮流數(shù)學(xué)模型,首次研究了磨刀門河口2011年地形條件下的枯季波生流場。受波浪作用影響,落潮階段,波浪作用方向與流向相反,在波浪頂托效應(yīng)下攔門沙沙脊及外坡處流速普遍減小,形成兩個主要回流區(qū),口門外東西兩側(cè)淺灘處流速也減小,東西兩汊及橫洲深槽流速增大;漲潮階段,波浪作用方向與流向相同,攔門沙沙脊及外坡處流速增大,沙脊處出現(xiàn)沖越流,口門兩側(cè)淺灘處流速增大,橫洲深槽流速減小。
[Abstract]:In this paper, the wave model of hyperbolic gentle slope equation in curvilinear coordinate system and the depth average 2D tidal current mathematical model considering the effect of wave radiation stress are established. Under the influence of wave action, the direction of wave action is opposite to the flow direction in the period of falling tide. Under the effect of wave top support, the velocity of the sand ridge and the outside slope decreases generally, and two main backflow zones are formed, and the velocity of velocity at the shoal on the east and west sides of the entrance door also decreases. The velocity of the deep channel increases in the east and west branches and in the transverse channel; In the high tide stage, the direction of wave action is the same as that of the direction of flow, the velocity of the sand ridge and the slope increases, the flushing current appears at the ridge, the velocity of the shoal on both sides of the mouth increases, and the velocity of the deep channel of the transverse continent decreases.
