| Abstract: | Coastal areas are varied in physical features. The coastline shows
constantly varying nature due to tidal effects and seasonal changes in wave and
wind climate. Occasional cyclones in the region also have influence on the
overall morphology. It is necessary to understand the coastal processes and
predict likely effects before undertaking any coastal project. Developments of
major/minor ports and fishery harbours consist of the construction of coastal
structures like breakwaters, jetties, groynes and reclamation bunds.
Developments of the ports also involve the dredging and disposal activities to
maintain the required depths for navigation. These coastal structures and the
dredging activities interfere in the coastal processes of the region.
Modifications in the coastal processes have large impact on the coastline. Major
morphological impact is felt in the coastal region having high rate of
longshore littoral drift. Accumulation of sediments on the updrift side and
erosion of the downdrift side is inevitable in these regions. Sand bypassing is
one of the best solutions to mitigate this problem. Sand bypassing should form
an integral part of any port development project at the planning stage. |
