Abstract

Taiwan coast is surrounded by the Taiwan Strait and the Pacific Ocean. Sandy coasts are majority and severely scoured by North-Easterly winter monsoon and summer and autumn hurricane (i.e. typhoon). Link block (shore protection concrete block) are largely placed along the beach or vertical to the beach or even arranged offshore parallel to coast (i.e. offshore breakwater) to induce sediment behind the offshore breakwater to reclaimed the lost sand of beach (i.e. beach nourishment). However, such as commercial harbor like Taipei Port, the armour unit of the breakwater are placed by Link Block For East Coast along the Pacific Ocean, the beach slope is very steep, therefore the toe of the coast highway (Highway No.9 & Highway No.11) need to be protected along the highway foundation to protect big waves act on the foundation and erode sand away. Link Block are then occupied largely along the shore to protect highway foundation and keep their stable and sound coast and foundation are not eroded away.
