Seasonal Beach Changes Along Quilon District Coast, Kerala

Based on the beach profile studies along the Quilon coast during the year 1980-81, accretional and erosional areas were demarcated in the southern and northern sector of the Neendakara outlet. A net gain of 0.194 m³ of sand in the southern sector and loss of 0.374 mimon m³ in northern sector was noticed. There is marked variation in mean grain size, sorting and foreshore slope in these two sectors. Reversal of longshore current from north to south, increase of breaker height and human activity have been found to be responsible for overall beach changes along the coast.
