Flow Characteristics of the Rip Current System near a Shore-Normal Structure with Regular Waves

Rip currents are the strong narrow seaward current produced by waves breaking on coast. Of many types of rip currents, present study investigates, experimentally and numerically, system wave reflection a finite-length shore-normal structure (corresponding to groin, jetty headland in real-word environment) with strength. The incident condition an obliquely propagating monochromatic surface gravity is considered for bottom topographies planar barred beaches without or channel. corresponding laboratory experiment was conducted used validate numerical model. A set higher order Boussinesq equations reproduce experimental observation produce results related prototype cases, latter considering more factors which may influence formation evolution flow patterns. resulting contains two parts: node rips formed due presence longshore standing field deflection interaction between incoming mentioned above. new mechanism has been proposed, i.e., meeting then lateral flow. effects different strengths structure, angles bathymetric conditions pattern volume also studied.
