Hydrodynamics and Siltation Study using MIKE 21 for Proposed Channel on South of Ennore,Chennai, Tamil Nadu

Abstract

In the Coastal region, the ports have become an important part of the development of the Coastal Region. In the study hydrodynamics and Siltation at the south of Ennore port. In the Coastal region, the ports or harbour has become an important part of the development of the coastal Region. In which many factors are important such as constructing the jetties, Breakwater, etc Due to the drastic change in the water many issues have been occurred such as siltation, sedimentation, Erosion, high water level etc. In this study, a channel has been proposed in the south of Ennore port for the development of the coastal region. Because the depth near the port is not sufficient for the huge ships to enter the port. Due to which the Economic aspect of Ennore Chennai gets affected. It was also being observed the change in the depth near the port due to the proposed channel. In this study, a -10m channel has been proposed in the Ennore port by the process of dredging. Due to which the total bed thickness changed slightly to about 0.5 m. Other parameters such as surface Elevation, Current Speed, SSC (Suspended Sediment Concentration) has been slightly changed. And for Mud Transport result there is slightly different in the siltation in the all four points in the Ennore port. Before the dredging, it is slightly high after dredging it is reduced. For further studies, it can be done at the port by taking different depths and calculating the seabed for dredging and will provide us accurate Solution.
