Abstract

On Ba Lang Beach in Nha Trang, Vietnam, the beach has been narrowed owing to land reclamation along the shoreline to construct a coastal road. The process of this artificial alteration was studied using satellite images, then the BG model (a model for predicting three-dimensional beach changes based on Bagnold’s concept) was used to investigate the feasibility of beach nourishment to recover the sandy beach. It was concluded that if we can procure the beach material of 6×104 m3, a sandy beach of 24 m width can be recovered at the central part of the beach nourishment area.
