Experimental and Theoretical Studies of Wave-Current Systems

本研究从理论上和实验上探讨了浅水中波流相互作用。实验室实验将在三维波盆中进行。在倾斜的海滩上会产生稳定的水流。以不同的频率和入射角产生小幅度波。在有无波流相互作用的情况下，将详细地测量流速和波幅。实验室数据将被分析并用于验证现有的理论，并作为新的理论研究的推动力。理论研究将集中在对振荡波影响下的稳态电流系统的理解上。特别地，电流波系统的稳定性将被检查。还将努力发展描述波流相互作用系统的数值模型。

This research investigates experimentally and theoretically wave-current interactions in shallow water. Laboratory experiments will be performed in a three- dimensional wave basin. Steady currents will be generated over a sloping beach. Small amplitude waves will be generated with different frequencies and angles of incidence. Measurements of current velocity and wave amplitudes will be made in detail with and without wave- current interactions. Laboratory data will be analyzed and used to verify the existing theories and to serve as an impetus for new theoretical investigations. Theoretical studies will be focused on the understanding of the steady current system under the influence of oscillatory waves. Particularly, the stability of the current-wave system will be examined. Efforts will be also made to develop numerical models describing the wave- current interaction systems.
