Abstract
The shoreline, which is the boundary line between water and land is undergoing constant changes due to varying dynamic factors like, bathymetry, wave climate, currents, and coastal orientation. Shoreline movement causes erosion and accretion on thecoast. The repeated storms and the rise in sea levels lead to coastal flooding and which contributes toerosion/accretion problem on the coast. For the present attempt, the shoreline evolution is analysed by using numerical method, due to the development of Thangassery harbour in Kerala coast in India. To predict the shoreline evolutions at Thangassery harbour Mike 21 SW and LITPACK modules are utilized. The studies reveal that after the harbour construction, there is tremendous accretion on the immediate south of leeward breakwater followed by erosion trend.
