dc.description.abstractPoompuhar, a flourishing port in the beginning of the Christian era played a major role in maritime activities and cultural expansion in the history of India. The marine archaeological explorations around Poompuhar brought to light the remains of terracotta ring wells, brick structures, storage jars in the inter tidal zone and brick structures, stone structures, pottery from offshore explorations strongly support the habitation sites. There are several references suggesting the shift of shoreline at Poompuhar and Tranquebar, which may be one of the reasons of its submergence. The main process directly responsible for shoreline change is influenced by the waves. The studies on waves were used to estimate the long shore sediment transport, which indicates the predominant direction of transport is northerly from March to October and southerly from November to February. Cyclones during north-east monsoon would considerably increase the volume of sediment transport towards south with a short spell. It is noticed that for the occurrence of every cyclone there was a permanent loss of beach due to erosion. The global sea level is estimated to be 1 mm per year and may have resulted in 2 m net sea level rise in the last 2000 years. Since the near shore bathymetry gradient is gentle 1 m sea level rise may cover up to several hundred meters of coastline. The recent inundation during tsunami was up to 500m from the shore. The paper deals with the archaeological findings around Poompuhar and the impact of coastal processes on the shoreline change in the area, which was responsible for the submergence of ancient port town and other monuments in the region.
