Abstract


Bali Turtle Island Development is a major tourism-related coastal development project situated in the SE corner of Bali, Indonesia. The project includes large-scale dredge-and fill reclamation for the purpose of enlarging the existing natural island of Serangan by 3.7 km2. The completed reclamation will include three artificial lagoons, four artificial pocket beaches, six artificial headlands and a causeway/bridge connection to the Balinese mainland. This paper provides an overview of the development project as a whole, as well as describing the numerous coastal engineering and environmental investigations that have been applied in the optimization of the design. Due to the complex bathymetry and interrelated wave, flow, sedimentological and water quality mechanisms, an integrated approach for design optimization was required. The steps taken for the management of dredging operations in the vicinity of sensitive habitats are also discussed.
