Thailand has 2614 km of coastline, 1660 km of which border the
Gulf of Thailand, while the rest faces the Andaman Sea [1]. Erosion
along the southern coast has damaged infrastructures and threatened
livelihoods of coastal communities. Since a certain erosion
mitigation measure that is successful in one location may not be
appropriate elsewhere [2], erosion management requires not only
an essential understanding of coastal physical processes to investigate
true causes of the erosion but also an understanding of the
underlying social and political structures to reduce possible
conflicts [3].
