摘　　要：苏北辐射沙洲海域地形复杂,为了了解大丰海域潮流特征,采用MIKE21水动力模块建立了苏北辐射沙洲海域平面二维潮流数学模型,利用实测资料对大丰海域的潮位和潮流进行了验证。验证结果表明,模型计算值与实测值吻合较好,所建模型能够正确反映大丰海域的潮流特征。数值模拟结果表明,大丰海域的潮流动力强劲,各区域流速较大,往复流特征明显。模拟结果为该海域的工程建设与环境保护提供了科学依据。The terrain of radial shoal region in the North of Jiangsu Province is complex.In order to understand the characteristics of tidal currents in Dafeng Sea area,a 2D mathematical model of tidal current for the radial shoal region is established by MIKE21 HD module,and the tidal level and current are verified with observed data in the Dafeng Sea area.The results show that the calculated and measured values are consistent.Therefore,the model can reflect the characteristics of tidal currents in Dafeng Sea accurately.The numerical simulation results reveal that the energy of the currents is powerful and the tidal current velocity is large with obvious reciprocating flow.The numerical simulation results provide scientific basis for engineering construction and environment protection of Dafeng Sea area.
