Fisheries Harbour Development: A Review

Abstract

Due to ever increasing trade and sea-borne traffic, new fisheries harbours and ports are required to be developed and expended the existing port with deeper and wider approaching channel. If a port is to be developed in the zone of high littoral drift, it is of vital importance to predict its effect on the adjacent shoreline and suggest remedial measures to minimize the adverse effects due to construction of the port. Rapid expansion of human activities in the coastal zone is causing several problems. There are various environmental forces like tides, currents, waves and sediment transports and pollutant transport associated with the coastal processes. This note deals with the forces against development of fisheries harbour and feasibility studies would be carried out for the fisheries planning in the coastal region. Scale model are long being used to study coastal engineering problem. Various models are used in dealing with coastal engineering problems particularly in fisheries harbours. Since last two decades mathematical modeling has become a very efficient tool for studying coastal engineering problem for fisheries harbour. These models are essentially based on conservation of mass and momentum equation. Similar to scale model, there are tidal model as well as wave model. These models can be three dimensional (3D) or two dimensional (2D) depending upon governing equation. It is suggested that the above methodologies should be followed for any development of fisheries harbours in India as well as other countries.
