    Abstract
    During the late Holocene, coastal configuration has undergone continuous changes due to various reasons like sea level fluctuations and shoreline shift. Several reasons are attributed like global warming causing polar ice melting, change in sedimentological regime in near shore region resulting in emergence or submergence of coast and neotectonic activity altering the elevation. Archaeological sites, when they elucidate marine connection and are presently away from shore, provide an unambiguous evidence of such phenomena. Our investigations at Bet Dwarka suggests, at least two historical period sites get submerged during high tides, indicating shore line shift in last 2000 yrs. One such site indicated liquefied layer in trench at about 2 m depth and the event is dated to 2000 yrs BP. Chilika region in Orissa is a classic case where shore line shift is observed. Tranquebar, also on the east coast, is another site depicting drawn coast. Time has come to carry out systematic investigations of the coastal archaeological sites that have proven maritime connections to decipher the scientific cause of their being defunct. Such investigations may provide an additional tool to understand complex jigsaw puzzle of shoreline shift in time and space.
