Description 1297-1305
This paper is a result of studies aimed at understanding morphological
changes of a straight-sandy beach in response to the site specific coastal
processes. Data collection includes beach profile surveys, bathymetry, and
particle size distribution of sand in breaker zone, analysis of historical
maps, satellite imageries, and tide and surface currents in the vicinity. Based
on monthly beach profiling, the shoreline was observed to be oscillating over a
distance of 30 m in normal climate conditions. However immediately after each
cyclone passage, there was a major shore retreat within a matter of few days. Numerical
model simulation and field data indicates that the cross shore sediment
transport is significant. This understanding is essential and plays a major
role in providing a sustainable shore protection measure to stabilize the site.
The study further deals with the assessment of the efficacy of shore parallel submerged
dyke using numerical models.
