| 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. |
