Topographical variations along the Tellicherry Beach during the southwest monsoon season

Abstract

The short term changes in the topographical variations of the Tellicherry Beach along five profiles (twice a week) was worked out at closed space interval of around 200 m. The maximum loss of material was observed along the southern sections. The predominant wave approach was southwest which resulted in a northerly littoral drift with varying speeds during the southwest monsoon season. The wave heights generally did not exceed 1.5 m except on few days when it exceeded 2 m which resulted in the erosion of the foreshore beach material. A tumbola formation was noticed on the northern side of the study area
