Abstract

An in-depth analysis has been made by integrating coastal ocean current-meter deployments and topographic signatures to simulate scenarios of transport and coastal circulation characteristics for understanding the nearshore sediment transport controls, and to identify the specific factors that play prominent roles in sediment transport controls and concentration of the beach placers at Manavalakurichi, along the southwest coast of India. Numerical simulations linking bathymetry, hydrodynamics, sediment load, and significant wave heights revealed that changes in bathymetry would amplify the wave heights and convergence of wave energy. Associated removal of sand from the high-energy zones will eventually lead to sediment starvation situations and depletion of placers in the adjacent beaches
