Abstract: | Shore-normal and shore-parallel variations in grain size statistics of beach sand have been studied over a period of one year
along the Kakinada-Mulapeta coast. The southern beaches of this coast have been accretionary while the northern ones erosional
since 125 years. The grain size gradings, beach and nearshore processes help in identifying (i) the Groins-fishing harbour
beach influenced predominantly by the tidal regime. (ii) the Mulapeta-Vakalapudi beach influenced by refracted wave regime
and (iii) the Vakalapudi-fishing harbour beach affected by both wave and tidal regimes at relatively subdued levels. |
