| Abstract: | The responses of a sandy beach to the southwest monsoonal waves are studied based on biweekly observations. The onslaught
of the first spell of monsoonal breakers causes maximum erosion in the sub-aerial section of the beach. However, further spells
of high breakers do not affect this zone significantly. The erosion in the sub-aerial zone is followed by accretion in the
nearshore zone and vice versa. Whereas the sub-aerial zone has a net erosion the total section of the beach including the
nearshore zone shows near equilibrium condition. It is concluded that in spite of erosion or accretion of the sub-aerial zone,
equilibrium conditions may be found in the total section of the beach. |
