Long and Short-Term Shoreline Changes Along Mangalore Coast, India
Kumar, A. & Jayappa, K. S.
Abstract
Eighteen kilometers long coastal stretch from the New Mangalore Port in the north to
Talapadi 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.
