Monitoring shoreline environment of Paradip, east coast of India using remote sensing

Abstract

In the present study, multi-temporal satellite images of Indian Remote Sensing Satellites (IRS1D and IRS P6 - Resourcesat) from 1998 to 2005 is used to monitor the coastal environment of Paradip, east coast of India. The resultant coastal vector maps were used to estimate the geomorphological changes and shifting of the shoreline position. This integrated study is found useful for exploring accretion and erosion processes in the region. The shoreline maps were compared with the 1973 Survey of India toposheets to estimate the changes which have occurred in the region. Results indicate an increase of 7.72 km in shoreline length and a net loss of 18.73 km2 of beach area between the years 1973 and 1998, and 0.46 km reduction in shoreline length and 3.11 km sup(2) increase in beach area between 1998 and 2005. An overall net increase of 7.26 km length shoreline and a net loss of 15.6 km sup(2) was observed between 1973 and 2005. The years 2001, 2002 and 2003 exhibited loss in length of shoreline as well as area of the beach. These years coincided with certain coastal activities carried out in the study region
