Abstract:
The tsunami disaster on September 28 2018 in Palu Bay was caused by an avalanche on the seabed due to an earthquake, resulting in changes in the bathymetry in Palu Bay. Changes in bathymetry affect hydrodynamics activity, which is one factor that influences sediment transport. This study aims to determine the effect of changes in post-tsunami bathymetry on sediment transport patterns in Palu Bay. This research was conducted by analyzing bathymetry changes before and after the disaster, followed by modeling currents and sediment transport using the MIKE 21. The results of the bathymetry change analysis showed a total landslide area of 6.552 km2 with a total volume of 0.163 km3 and a total stockpile area of 6,689 km2 with a total volume of 0.580 km3. Modeling results in hydrodynamics using the MIKE 21 application. The current velocity value after a disaster occurs increases with a range of values from 0.003 m/s to 0.145 m/s. The results of the Sediment transport modeling show that there was a change in sediment transport patterns at several points. It can be concluded that changes in bathymetry in Palu Bay affect the current velocity, and are directly proportional to bed level change.
