Modelling of flow characteristics in the access channel of Bali tourism port using DualSPHysics

Abstract

The access channel is a structure formed as a basin on the seabed. Based on previous studies, excessive sediment accumulation in shipping lanes or access channels carried by ocean floor currents is one of the factors that cause damage to the hull under the ship. Therefore, this study aims to investigate the characteristics of seabed currents that cross the access channel. This research was carried out by modelling the numerical test of the access channel model using the Smoothed Particle Hydrodynamics (SPH) method with DualSPHysics software. The results of this study show the movement and characteristics of seabed currents that occur in the access channel at the Bali Sanur Harbor. This study obtained the average speed of seabed currents, with variations in the speed of ocean currents and forecasts regarding sediment dredging maintenance on cruise lines.
