Studies on the dynamic response of coastal sediments due to natural and manmade activities for the Puducherry coast
1322-1326This
paper presents the response of the coastal sediments by the impact of waves and
construction of manmade structures in the Puducherry coastal stretch, East
coast of India.
Based on the real time wave climate data which was collected from the nearshore
region of coast using wave rider buoy and wave direction indicator. The quantum
of sediment movement is calculated using CERC formula for three years (2007,
2008, and 2009) and compared with Kamphuis method for one year i.e., 2009. In
order to achieve a more reliable value on the sediment movement a sand trap was
used at the littoral zone to collect the actual sediment samples for a period
of two months i.e., February and March 2009. For all the three observation
period the predominant sediment transport rate is Northerly. Estimated sediment
transport rates were also determined by Kamphuis method. From the results
obtained, CERC formula ‘over predicts’ the sediment transport rate when
compared with Kamphuis method. The actual sediment transport calculated using
sand trap was found to be 60% reliable when compared with theoretical sediment
transport rate which has been determined by using Kamphuis method.</span
