Modelling Shoreline Evolution at Anmok Beach by Using CST3D-WA

Anmok Beach suffered heavy morphological and shoreline position changes since a submerged breakwater was constructed in Odober 2014. Straight shoreline changed into a S-shape shoreline after about 3 months, and mostly returned back towards the initial straight line after typhoon Goni in August 2015....

Summary:Anmok Beach suffered heavy morphological and shoreline position changes since a submerged breakwater was constructed in Odober 2014. Straight shoreline changed into a S-shape shoreline after about 3 months, and mostly returned back towards the initial straight line after typhoon Goni in August 2015. Previous wave-average type flow and sediment transport equations cannot reproduce shoreline evolution due to their "wave-average" properties. A wave-average flow and sediment transport model, CST3D-WA, adopt the "beachface slope adjustment method" to enable shoreline evolution in area morphological modelling. The modelling system simulated the morphological change for Iwo periods, and reproduced Ihe changes in morphology and shoreline shape of the two periods reasonably well.
