LITTORAL DRIFT MANAGEMENT—A SUCCESS STORY OF VISAKHAPATNAM PORT
Though the complex littoral drift phenomenon is left unnoticed on natural open coasts in view of its ‘large time-scale’ evolutionary effects on beach morphology, the same can never be ignored when open coast port developments are planned particularly in large littoral drift regions. This paper reveals the success story of port of Visakhapatnam which was designed with integrated vision, considering the various aspects like wave tranquillity, siltation etc. including the morphological aspects. By providing offshore south breakwater with a gap to allow entry of littoral drift sediments towards a protected sand trap within the harbour and proactive actions of regular sand bypassing on down drift reach, a 3 km long beach could be created and maintained. The inferences drawn from systematic analysis of about 30 years beach profiles data till 2009, collected in the post outer harbour period clearly depict the success rate of various strategies adopted for dredging and disposal of sediments in tackling the littoral drift phenomenon. The analysis presented in this paper reflects the true character of down drift beaches in response to the artificial sand bypassing and thus useful for design of appropriate measures for similar development projects on the east coast of India.
