Abstract

Various types of erosion prevention facilities installed for the purpose of protecting the beach have been proposed in order to effectively control the waves and wave induced current as well as being installed at a relatively close location to the coast. If the erosion control facility designed to control the waves and wave induced current is overshadowed, the seawater flow in the facility will become stagnant and water quality problems will arise. In this study, the effects of seawater exchange in the back side of the structure were investigated under various conditions through the three-dimensional physical and numerical model test when a beach erosion countermeasure facility was installed. A seawater exchange facility was devised for seawater circulation inside the overshadowed coastal prevention structure and flow analysis was conducted on the effects on seawater exchange according to change in location of the seawater exchange facility, while also analyzing the seawater exchange rate according to particle tracking.
