摘要：Coastal wetlands, the places where the sea water meets the land are unique places in our global geography. They are endowed with a very wide range of coastal ecosystem like mangrove, coral reef, lagoon, sea grass, salt marsh and estuary. Wetlands offer myriad ecological benefits like flood control, ground water recharge and shoreline protection besides being cradles of biodiversity and habitats for waterfowl. Remote Sensing (RS) and Geographic Information System (GIS) in recent years have proved to be of great importance for effective resources management and coastal environmental monitoring. In the present study, an attempt has been made to delineate various coastal wetlands along Kollur-Chakra-Haladi, Sita-Swarna and Udyavara river systems in Udupi district of Karnataka. The study area geographically lies between the 13°10’ N to 13°40’ N latitudes and 74°30’ E to 75°20’ E longitudes. Fourteen types of wetlands are identified in the study area covering a total area of 495 ha
