Coastal Abrasion and Sedimentation Kota Bengkulu Coast Area

Muhammad Hasanudin, Edi Kusmanto


Coastal Abrasion and Sedimentation Kota Bengkulu Coast Area. Coastal environment of Kota Bengkulu is typified by strong wave energy, which caused coastal abrasion and sedimentation. This paper intends to discuss the abrasion and sedimentation processes in the coastal area of Kota Bengkulu. Bathymetry survey has been employed to measured the depth of ocean floor, together with turbidity of water, and tide and wave currents. The erosion in the coastal Kota Bengkulu occurred as a result of the strong waves which hit coastal cliffs intensively and high rainfall conditions that weaken the bond-forming material at the foot of the cliff coast. On the other hand, sedimentation occured due to the supply of sediment from the collapsed material of the coastal cliffs that are transported by the current in the Coastal Waters of Kota Bengkulu together with Jenggalu River and Air Bengkulu River.
