Abstract
    During late November and early December of 2015, Chennai city in the coastal state of Tamil Nadu experienced unprecedented rainfall that resulted in a flash flood. It was one of the worst affected coastal cities of southern India resulting in an alteration of the coastal environment. We was made an attempt to document the impact of the flood on coastal fauna following which a survey was conducted from the estuarine river mouths of Adyar to Cooum along the Marina beach. 177 marine species were identified, represented by 5 fishes, 15 crustaceans, 95 bivalves, and 57 gastropods. Other groups include echinoderm, coral, polychaete, anthozoan and bryozoan represented by a single individual. Presence of various freshwater species including various plastic components indicates that the heavy freshwater outflow from the rivers and canals have had a notable effect, calling for a long term assessment of the study area.
