Shoreline Changes Around Three Estuarine Harbours on Kerala Coast in India

Abstract

The shoreline, the land and water boundary is subjected to periodic changes due to different dynamic factors like, bathymetry, wave characteristics, currents, and coastal orientation. Coastline variation leads to erosion and accretion phenomena on the coast. In the present study, the coastal changes around three estuarine harbours along Kerala coast in India are analysed by using numerical method. The impact of harbour constructions on shoreline are assessed from this study. Mike 21 SW and LITPACK modules are used to predict the shoreline changes at these three estuarine harbour sites along Kerala coast. The analyses on coastline oscillations around three estuarine harbours show significant impact of harbour constructions on adjacent coast.
