| Abstract | Storm waves erode the beach sand and accumulate in the off shore zone causing shoreline retrogression. Subsequent post storm decaying storm waves or swell waves transport back the sand and accumulate in the onshore zone resulting in the advancement of shoreline. This cyclic behaviour of beach transformation and onshore-offshore sediment transport are dependent on wave and beach characteristics. Information on morphological response of beach transformation and a quantitative knowledge on onshore-offshore sediment transport are essential as engineering tools to describe practical coastal engineering problems. This study aims to visualize i ) the mode of sediment transport whether onshore or offshore and ii) the pattern of beach transformation to iii) quantify the onshore-offshore sediment transport volume through a laboratory experimental inflame. It is found from the laboratory experiments that i) beach behaves distinctly the cyclic transformation when storm waves are followed by swell waves; ii) sediment transport at the early stage of generation of storm or swell waves is prominent but decays exponentially and iii) the volume of onshore, offshore sediment transport or average of combined transport can be expressed by empirical relationships with wave and beach characteristics. |
