The Effect of Dadap Port Structure in Indramayu on Coastal Morphology
Human activities in coastal area will generally lead to a greater erosion rate due to the loss of natural protection or inappropriate structure. Dadap Beach, located at Juntinyuat District, Indramayu, West Java is one of the locations experiencing problems above. In 2003, a Fishing Port was built on...

| description | Human activities in coastal area will generally lead to a greater erosion rate due to the loss of natural protection or inappropriate structure. Dadap Beach, located at Juntinyuat District, Indramayu, West Java is one of the locations experiencing problems above. In 2003, a Fishing Port was built on Dadap Beach, with structure jutted 200 m from the shoreline to prevent sedimentation. However, currently there has been a massive sediment deposition in the port pool and behind the port. This study aims to determine the sedimentation pattern in Dadap Port, and the influence of the port structure on the coastal morphology, using a numerical model simulation. The results of this study indicate that the presence of the port structure has caused wave diffraction that forms a circulation flow behind the port structure and around the entrance area to the port pool, that lead to the formation of a tombolo behind the port and the sediment from the longshore currents and local scour enters the port pool area. Furthermore, the existence of Dadap port structure causes the obstruction of longshore currents so that the supply of sediment to the area around the port is reduced and the erosion rate is increasing. |
