Characterization of Sediment Dynamics in the South- Eastern Shelf Zone of Bangladesh

Md. Mahfjur Rahman [2]


Abstract: The stable and deeper southeastern shelf zone of Bangladesh has a wide continental shelf including with the alongside tertiary hill, piedmont plain, intertidal plain, supratidal plain, fluviotidal plain, barrier island and channel which are always feeding the sea bed of our shelf with large sediment deposition. The primary objective of my study is to findout the sediment distribution onto the sea bed our southeastern shelf zone. Besides, I have tried to show the vertical and horizontal sedimentation based on the different sands and sizes. I have also tried to present space and depth relationship with the sediment dynamics onto the sea bed. The study was undertaken on the 27 poins os sample collection of five major places i. e. Sonadia, coxs Bazr, Inani, Teknaf ( shah-parir deep) and St Martyn. The sediment samples including water from deeper sites were collected by sediment grabber and water sampler and they were examined by the Hydrometer and Sieve techniques and filtration method for the Suspended solid determination. Vertically, the suspended solid were more at the bottom accept some i. e. Coxs Bazar were more at surface. By the study, it is clear that with onward movement towards sea the particles become more sorted and smaller resulting in more silt and clay whereas the near shore and land based samples show more sands in amount. The innermost points show coarse silt at more rates than other silt meaning these innermost points are mostly of sandy silt. The sedimentation rate is being accelerated due to different natural phenomena and human intervention.
