Description 31-36
Morphological and grain size studies have been carried out at
monthly intervals (February 1993 to February 1994) to understand sedimentation
pattern. Eight study sites were selected for morphological studies and five for
grain size studies. It is observed that the morphological changes are cyclic
i.e. erosion during monsoon and deposition during fair-weather season. The
beach has experienced a loss of about 951 m3/m-1, a gain
of about 1677 m3/m-1 and hence a net gain of about 725 m3/m-1
of sediments along the line of transect (all the 8 stations together) over a
period of one year. A secondary cycle of erosion is observed between December
and February. In general, the sediments of the study area are fine grained,
well sorted, and symmetrical and platykurtic in nature. Mean grain size
decreases, sorting improves and percentage of fine sand, positively skewed
grains increases from north to south (G1 to G8). Beach experiences moderate
turbulent energy conditions and the sediment movement is towards south in this
beach .The prevailing conditions in this beach are ideal for recreational development.
