Abstract: Land reclamation refers to the land filling at the coastal area or any form of water body for development purposes. It is one of the popular methods to acquire more land for development purposes. However, undesirable land reclamation designs has raised concerns by various groups such as environmentalists, politicians and other related parties as it potentially can cause major impacts particularly on the marine environment. Subsequently, this leads to various mitigation measures to be undertaken to mitigate the side effects from reclamation. The present paper discuss the optimization process applied for a reclamation site located close to Malaysia-Singapore international border. Key elements in the layout optimization procedure includes understanding of existing guidelines, natural conditions and application of numerical modelling tools (Mike 21 FM HD). Natural conditions such as bathymetry contour is utilized in the optimization process to identify the potential area to be reclaimed and inspired the establishment of the preliminary shape of the land reclamation. MIKE 21 FM HD tool is applied to describe the hydrodynamic characteristics such as ocean, lakes, estuaries, bay and coastal regions with response to various hydraulic forcing. Subsequently, the hydraulic flow condition in the study area can be derived and layout optimization proceeds with streamlined based on the hydrodynamic flows. The result of the study shows the potential impact on the hydraulic environment from optimized layout particularly along the international border is reduced with the increase in land reclamation area size. Thus, benefit of an optimized layout is not limited to reduction in the potential hydraulic impacts but also reduce the need to implement additional mitigation measures which thus assist in cost and time saving
