Abstract
Baseline information on the beach Abstract: morphology along the Ennore coast, an industrial hotspot region in the East coast of Bay of Bengal, is presented. In order to assess the effect of human interference on the coastal zone, a baseline survey of the coastline is considered important. Such information enables to predict the future coastal morphology and settings. Based on the baseline data created, this study predicts that the accretion noticed in the southern side of the Ennore port will affect the port entrance channel in the future course. Therefore it warrants for immediate mitigation measures to curtail such accretion and also recommends for keeping the Ennore creek mouth open permanently. Ennore creek also serves as the coolant source for the two thermal power plant units. The study also put forward certain other mitigation measures which are relevant in the present event of developments. Adjacent to Pulicat Lake, the erosion is continuously taking place at an alarming rate making vulnerable for a striking storm to wash away the villages under the sea. It may also lead to the merger of the Pulicat Lake into the Bay of Bengal, thereby the brackish water ecosystem of the lake may altogether disappear causing several ecological and social problems. The study concludes that a long-term integrated coastal monitoring is the need of the hour

Summary
Throughout the world, coastlines are the brutal victims of the anthropogenic activity. Partially due to rising sea levels, is often exacerbated by human interference that disrupts the natural sediment transport processes along the coastline For such a sort, the North Chennai coast, in the Ennore coastal stretch, could form a typical case study. A coastal stretch of about 30 km length, lying between 13o 12’ 30” N and 13o 30’ 00” N latitude and between 80o 00’ 00” E and 80o 27’ 30” E longitude extending from EID Parry factory on the southern side of Ennore Creek to the inlet of Pulicat Lake along the coast of Bay of Bengal has been chosen as the study area (Figure 1).
