Estimating the longshore transport energy and transport rate at UMT beach using LEO data

Abstract

This study was done in order to quantify the longshore transport energy and transport rate thus the variability in energy and sediment transport at UMT beach for November and December 2007. Data of beach parameters were observed daily and recorded under the Littoral Environmental Observation (LEO) data collection program for at least 16 days per month while the empirical equations listed in Shore Protection Manual were used to analyze the data. Dominant wind direction for the two observed months were from the North East direction with speed ranging from Om/s and l 3m/s. Dominant wave approaching the beach were from the angle of I 00 ° from the shoreline while the longshore current velocity at UMT beach ranged between 0.07m/s and 0.41 m/s. Range of longshore transport energy is between 0.0 I kg/s and 1.48kg/s, transporting sediment to the North of UMT beach at an average rate of2436m 3 /day.
