The Disturbance of Sediment Transport Balance in Mangrove Forest East Lampung, Lampung

Mangrove ecosystem in coastal area of east lampung regency had had serious disturbance. the disturbance of sediment transport balance in the coastal of east lampung regency affected the mangrove ecosystem a lot. This research aimed to determine the disturbance of sediment transport balance and mangrove ecosystem that affected the coastal area of east lampung regency. The result of this research showed the disturbance of sediment transport balance and mangrove ecosystem happened through 3 phases. Phases 1 : abrasion process increased but it had not passed the balanced limit and also the wide of mangrove ecosystem; phase II: the abrasion process was getting increased and passes the balanced limit; phase III: the abrasion process was getting increased passed the mangrove ecosystem limit. The cause of the balanced disturbance was carrying capacity of the coastal area of east lampung had ecosystem disturbance. According to the soil texture, the physical character of soil in sediment transport in mangrove ecosystem had composition of: sand: 10,495%, silt: 23,035%, clay 66,47%.
