Abstract
The coastline is constantly changing due to tides, waves, sea-level rise and fall, storm surges, land erosion, accretion, etc. This type of erosion and accretion has an intense effect on coastal areas. The area from Puri to Ganjam on the Orissa coast is relatively densely populated. Chilika Lagoon is located in this area and plays an important role in controlling the economic and social life of the region. Shoreline erosion and deposition affect the livelihoods of the area around Chilika Lagoon. About 70 km long sand spit is protecting the Chilika Lagoon and its biota. Erosion and accretion in front of the Chilika lagoon spit are very important for the survival of the largest lagoon in Asia. Some parts of the study area are prone to erosion and some are prone to accretion. There are various methods to calculate coastal erosion and accretion rates. Various coastal mapping techniques have been developed during the last 50 years. This work uses the Digital Shoreline Analysis System (DSAS) to calculate the amount of erosion and deposition along the Odisha coast from Ganjam to Puri. Later, this study area was surveyed and the results of the DSAS software were verified with the actual situation.
