Abstract
Wave climate of the nearshore region along Chennai Southeastern coast of India was simulated using MIKE 21 Nearshore wave module NSW Assessment of longshore sediment transport between Pulicat and Ennore was carried out using LITPACK Typical wave spectrums for the three seasons – premonsoon monsoon and postmonsoon at 10 m and 4 m depths exhibit the sea condition during postmonsoon swell condition during monsoon and the combined sea and swell condition during premonsoon Simulation show reasonably good comparison with buoy data in terms of wave height with an underestimation of wave period and direction The correlation coefficient for significant wave height is 042 and 082 during the transition period and non monsoon period respectively The littoral drift assessment has given a clear picture on how the current speed and direction play a major role in sediment transport Sediment transport of about 09 × 106 m3 towards north and 02 × 106 m3 towards south results with a net northerly littoral drift of 07 × 106 m3/annum
