Abstract
Eighteen kilometers long coastal stretch from the New Mangalore Port in the north toTalapadi in the south has been studied in order to understand shoreline changes and erosion/ accretion patterns that have taken place due to the natural processes and anthropogenic activities. Shoreline changes and quantification of beach erosion/accretion were made using the Survey of India topomap, multidated satellite images and beach profile surveys. During 1967-97 period, most of the beaches were accreted, except those lie just towards south of the Netravati and Gurpur river mouth in Sector III. During 1997-2001 period also, the beaches showed accretion trend, but they were subjected to severe erosion during 2001-05 in all the four sectors. The beaches in Sectors I-III are polluted due to discharges of effluents and very poor maintenance.
