Abstract
Nha Trang bay, located in the south Central part of Vietnam, have been widely considered as one of 29 most beautiful bays in the world. It is a center of tourism and services, which plays an important role in economic development of Khanh Hoa province. However, its coast is facing severe erosion problems threatening the existence of sandy beaches as well as many seaside properties. Especially, the Ba Lang beach is very vulnerable. In order to halt coastal erosion and stabilize the shoreline, submerged breakwaters (SBWs) are introduced to apply for this area. SBWs are being interested in beach protection, mainly due to less loss of beach amenity and their low aesthetic impact, which are important for maintaining the tourist value of sandy beaches. Nevertheless, SBWs have rarely been used for beach coastal protection in Vietnam; the morphodynamical response to these structures is not clearly understood at present. Therefore, the main aim of this paper is to investigate the effects of SBWs in hydrodynamics and sediment transport by using the numerical models of MIKE21, including hydrodynamic (HD), spectral wave (SW), and sand transport (ST) models. The results demonstrate that SBWs can be an effective measure to protect Ba Lang beach to a certain degree in both ordinary and strong wave conditions.
