Abstract: Identification of the shapes of sand spits and beach sediment accumulations at headlands, as seen in a sequential time coverage of aerial photographs, have allowed interpretation of the net directions of present-day beach sediment transport by littoral drift along the East Coast of Peninsular Malaysia. Changes in the shapes of the sand spits with time have, furthermore, allowed determination of the average, annual rates of the beach sediment transport. A dominantly south to southeastward present-day beach sediment transport by littoral drift is identified and interpreted to primarily result from the oblique approach of southwestward directed sea-waves and swell from the South China Sea during the NE monsoon. Deviations from this dominant direction, and variations in the rates, of the beach sediment transport are, furthermore, identified to result from the influence of the orientation of individual coastal segments, the presence of coastline protrusions and nearshore islands and the discharges of rivers at their outlets.
