A Numerical Simulation of Wave and Sediment Transport in The Balikpapan Bay, East Kalimantan, Indonesia

The couple system between shallow water waves model (SWAN) and hydrodynamic regional ocean model (ROMS) was used to simulated the influence of waves affected by wind on sediment transport processes in the Balikpapan Bay, East Kalimantan, Indonesia. The models were simulated from 1 June 2011 to 20 June 2011. The comparison of the elevation calculated by numerical model and observation data during 14 days. Good agreement was found between model results and observed temporal and spatial variations in water elevation. The results of study showed that the highest waves height distribution located in eastern and the lowest wave height distribution located in western and in the inner of Balikpapan Bay. Whereas sediment distribution generally concentrated in the shallow water and the sediment concentration largely accumulated in the downstream of Balikpapan Bay and its surrounding coast region.
