Beach classifications in response to south-west monsoon waves: A case study

Shamji, V R

Abstract

In scientific literature, classification models of beaches according to numerical and theoretical parameters are abundant. This study shows a case study concerning how a sandy beach responds morphologically to monsoonal waves and how the beach is classified as per energy conditions. The dynamics of sediments besides the related morphological variations are expressed as functions of incident wave’s climate, traits of sediments, and various environmental determiners. This study substantiates quantitative correlations between incident wave’s energy flux, sand grain size, fall speed parameters, and wave’s steepness and as sorts beach as per conditions of energy via multiple empirical functions. Additionally, a criterion corresponding with the direction of motion of sediment according to shifting waves’ climate is also suggested and verified under field environment.
