Abstract

Establishment of fishing harbour and fish landing centre is the most important activity for the development of marine fisheries infrastructure. However, littoral drift can be seriously impacted by the construction of fishing harbour and if due consideration is not given during construction of breakwaters, it may result in severe siltation on one side of harbour and erosion on the other side. This can eventually lead to complete failure of the harbour and result in a huge economic loss. To prevent such situation, mathematical modelling tools can play a significant role in estimating quantum and extent of littoral drift and assessing shoreline changes. Emphasis should also be given to corroborate the findings of mathematical modelling with actual field data. In this paper, a mathematical model study of shoreline changes has been undertaken for a proposed fishery harbour at Juvvaladinne on the east coast of India. It was found that annual northward and southward drift were of the order of 0.297 million cum and 0.001 million cum (almost negligible), respectively, while net and gross transports were estimated as 0.297 million cum and 0.298 million cum, respectively. Net transport was towards the north. It was also observed that northward transport was dominant during all periods. After 10 years, maximum cross-shore advancement is expected to be about 170 m on the southern side of the harbour while the maximum recession is expected to be about 130 m on the northern side of the harbour. The corresponding longshore effect of deposition and erosion was felt for 1500 m and 1300 m, respectively.
