Longshore sediment transport direction along Merang to Penarik Beach area

Abstract

The study of Longshore Sediment Transport Direction was conducted in Merang farther to Penarik beach which both are in the district of Setiu, Terengganu. The study was conducted to figure out the processes responsible in the longshore sediment movement pattern include the physical process, natural event and also sediment distribution pattern. There were nine sampling stations pointed out with the sampling session covers from August to December 2009. The alteration of the beach profile encompasses of erosion and deposition phenomenon for overall station with the steepest gradient of 15.57 ° of the beach slope which located in Bari Beach. The study area was comprised of 80 % poorly sorted sediment which indicates the coarser sediment dominantly distributed. The physical process predominantly altered the natural condition of the beaches in addition with the natural events such the North East Monsoon season which prevailed between November to December 2009 with the maximum wind speed of 8.5 mis. Regarding all the parameters measured, the direction of longshore sediment movement was determined from the southeast direction towards the northwest part of Kuala Terengganu.
