Abstract

The paper presents the results of the novel modelling of the wind-driven current in the southern Baltic Sea. The steady current is accompanied by wave-induced orbital velocities. The bed boundary layer related to wave-induced oscillatory flow gives rise to the appearance of additional shear stresses affecting the wind-driven current. This impact included in the wind-driven current model yields a modified logarithmic velocity distribution. Theoretical velocity profiles are compared with the field data. The measurement database includes wind, wave and current parameters. The velocities and directions of the wind were collected from the anemometer installed at the Coastal Research Station (CRS) in Lubiatowo. Wave-current parameters at a depth of about 17 m were obtained from a location of approx. 1.5 Nm from the shoreline in the vicinity of CRS Lubiatowo. The study site hydrodynamics is typical of the south Baltic coast. The analysis shows good agreement between the measured flow velocities and the theoretical vertical distributions in the form of the modified logarithmic profile.

非潮海远滨风致流速的修正对数分布

本文介绍了波罗的海南部风动流的新模型的结果。稳定的电流伴随着波动引起的轨道速度。与波动引起的振荡流有关的床层边界层引起影响风驱动流的附加剪应力的出现。这种影响包括在风力驱动的电流模型中，产生了一个修正的对数速度分布。将理论速度剖面与现场数据进行了比较。测量数据库包括风、浪、流参数。风速和风向由安装在Lubiatowo海岸研究站(CRS)的风速计收集。在深度约为17 m的波流参数，从大约的位置。距离CRS Lubiatowo附近海岸线1.5海里。研究地点的水动力学是典型的南波罗的海海岸。分析表明，实测流速与修正对数剖面形式的理论垂直分布吻合良好。
