A sediment budget calculation for Paradip port, situated on the east coast of India, is presented, taking into account longshore sand transport and nearshore erosion and deposition. Longshore sand transport rates have been computed using a CERC formula for which the average breaking wave characteristics, obtained from wave refraction diagrams were used. Quantities of nearshore erosion and deposition were obtained from the analysis of near-shore profiles. The study reveals that a quantity of nearly 0·8 million m3 of sand is deposited in the approach channel, while as much as 1·3 million m3 of sand is removed from the northern side of the port annually. It is also clear that the dumping of sand dredged from the port and its approaches beyond the 11 m depth contour on the northern side of the port, does not help to prevent erosion to the north of the port. © 1990.

Ocean and Shoreline Management

In order to have an understanding of the coastal processes along the southwest coast of India (8°4′ N, 77° 33′ E to 8°13′ N, 77°14′ E), a data set available for the changes in beach width for a period of 5 years (1993-1998) over a length of about 50 km was categorized and analysed in relation to the seasons. Since the study area is densely populated and was also affected partially by the great Indian Ocean tsunami, a fresh measurement campaign of beach profile changes up to a water depth of 6 m at four different locations along the coast was carried out. These measurements have been adopted to validate a finite difference-based numerical model that employs the empirical formulation of Larson and Kraus (1989) for the prediction of beach profile changes. We simulated the offshore wave climate from National Centre for Environmental Prediction wind data using the Wave Analysis Model (WAM), whereas the nearshore wave climate was derived by adopting the MIKE21 Parabolic Mild Slope module. Results compared well with each other. The prediction from the numerical model revealed that the average onshore-offshore transport varies from about 50 to 200 m3 y-1m-1 width of the beach. © Coastal Education &amp; Research Foundation 2011.

Numerical modelling and measurement of sediment transport and beach profile changes along southwest coast of India

The maritime state of Tamilnadu located along the south east coast of India has a coastline of length of about 950 km orienting in the east and west coast. The coast has undergone the catastrophic effect of Tsunami of 2004 and protection measures in the form of groins were completed. In order to assess the beach formations it is necessary to have an understanding of sediment transport pattern along the tip of India peninsula. Measurement of the shoreline changes adjacent to shore connected structures were done in 2007 and satellite imageries were also adopted to assess the direction of littoral drift. A numerical model was formulated and was used for the prediction of the observed shoreline changes adopting the generated shore wave climate generated. Based on the predictions the along shore sediment transport rates were estimated to be 82000 to 40000 m3 directed towards north and west directions respectively © 2011 ASCE.
