The Effect of Permeable Groin on Longshore Curre

| Summary: | Breaking wave on a beach at certain angle generates longshore momentum flux that causes longshore current.Such longshore current may be controled by coastal structures such as groin. The objective of this research is to study the influence of permeable groin on the velocity of longshore current. Permeable groin may be used to control and hence optimize the magnitude of longshore
current and the longshore sediment transport.
This research study the influence of permeable groin on the longshore current under various groin permeability. The model used in this research was a fixed bed model with bottom slope of 1:6 (vertical: horizontal). Two different groin permeabilities were selected for the research, these were 46.67% and 80%. The results of this research showed that groin structure modify both the direction and velocity of longshore current. The 46.67% groin permeability resulted in larger reduction of longshor current when compare with that of 80% permeability. |
