Description 233-239
The study covers the short- and long-term beach volume changes, shoreline
changes, wave refraction pattern and nearshore wave energy distribution. In
general there is a decrease of wave energy towards north. The distribution of
wave energy for monsoon shows that the highest value of 5215 J/m2 is
found in the southern most station and lowest value of 4043 J/m2 is
found in the northern most station. The computation of short- and long-term
beach volume changes indicate that the beaches of the southern sector are
nearly stable while the northern sector beaches are eroding. In addition to the
wave and wave-induced processes, the anthropogenic factors such as sand mining
by IRE, presence of breakwaters at Ashtamudi inlet and lack of sediment supply
from the rivers contribute to the continuous erosion in the northern sector.
The erosion/accretion pattern closely follows the longshore energy gradient
except in locations where anthropogenic factors dominate.
