Coastal morphodynamic The research was carried out on the coastal of Jeneberang estuary, to understand the coastal morphodynamic based on sediment backshore. Location of the research is along the coastal from Barombong Beach in south to the Tanjung Bunga Beach the north about 8.5 km length. The research method is drilling at Barombong Beach, Tanjung Bayang Beach, Tanjung Merdeka Beach, and Tanjung Bunga Beach about 10 meters ??? 11 meters depths..The sediment of core drilling were analyzed sedimentary texture, structures and compositions. Data of sediment backshore was correlated. Based on the analyzed of core drilling, the backshore sediment on the study area consist of sands, silts, clays, clay and sand with organic matter content. Sediment backshore at Barombong Beach shows a model of marine sediment, while at Tanjung Bayang Beach, Tanjung Medeka Beach, and Tanjung Bunga Beach show a model of fluviatil delta sediment.. These sediments consist of delta plain sediment, delta front sediment, beach sand sediment, and foreshore sediment. The Barombong Beach is a stable coast, however others are unstable coasts. |
