Implication of shoreline and nearshore morphological changes on sediment budget of wave-dominated Chennai beach, India

The study examines the shoreline (1990–2019) and nearshore morphological changes (seasonal) to understand littoral drift sediment budget variability. Shoreline change rate depicts erosion (− 0.06 m/year) in northern sector accretion (+ 0.12 southern sector. Seasonal from non-monsoon monsoon period signifies net 1.8 × 104 m3) 2.5 Although lost during is regained period, quantity of gain reduced areas with human interventions. results investigation depict dominance towards north February October, when wave approach east-southeast south-southeast direction southwards November January was east-northeast east-southeast. longshore transport estimated 2.6 105 m3/year 1.5 higher attributed than non-monsoon. Sediment deciphering causes 1.27 m3/year) (3.91 wave-dominated Chennai beach.
