Abstract
The present study investigates the runup patterns formed during the interactions of a solitary wave with an array of idealized structures in the presence of following and opposing steady current flows. A series of experiments were performed at Coastal and Hydraulic Engineering Research Laboratory (CHERL) of Stony Brook University. A solitary wave of 0.1 m high was considered to interact with an array of idealized buildings on a beach berm. The wave was generated in the flume in the absence and presence of steady currents. Two different steady current velocities, one weaker and the other stronger, were generated using the flume flow recirculation system.
Highlights
The attempts to quantify the dynamics of wave – current interactions are primarily focused on the interactions between short waves and currents
This study presents, for the first time, experimental and highfidelity numerical investigations of the interactions between a solitary wave and an array of structures on a berm beach (Figure 1) in the presence of steady following/opposing currents
The runup patterns significantly differ for the different flow conditions
Summary
INTRODUCTION The attempts to quantify the dynamics of wave – current interactions are primarily focused on the interactions between short (regular/irregular) waves and currents. A limited number of studies, deal with the interactions of solitary waves and currents (Zhang et al, 2014). Very few studies consider interactions of such complex flows with a group of structures. This study presents, for the first time, experimental and highfidelity numerical investigations of the interactions between a solitary wave and an array of structures on a berm beach (Figure 1) in the presence of steady following/opposing currents.
