ABSTRACT
Development of fisheries harbour alongwith major port is one of the requirement of the local fisheries community to provide all weather tranquil area for the landing of the fishing vessels such as trawlers, fish boats, etc., upto the draft of 3 m having sufficient cold storage land facilities and necessary inland road transport to the major market in the vicinity. Normally, these fisheries harbours are located on the down drift side of the main breakwater of the major port or adjacent to it.
The requirements of layout of the breakwater for the fisheries harbour are to make the design cost effective by providing navigable access, adequate tranquillity, optimum working area and minimum siltation in the harbour. The physical model play significant role to evolve a breakwater layout by making suitable minor deviations in the alignment of the breakwater to achieve wave tranquilly and minimize the siltation without additional expenditure for longer breakwaters.
In this paper, efforts have been made to highlight the role of model studies through peculiar cases of fisheries harbours at Kulai, New Mangalore and Chennai where minor deviations in the alignment and length of breakwaters were cost effective during planning as well as in post constructional stages.
The significance of advances in modeling techniques in simulation of boundary conditions and data acquisition system on the response and interpretation of data is highlighted.
