The analytical and data integration capability of GIS and the
spatial, temporal, spectral and radiometric resolutions of
remote sensing help to gain insights into the biophysical
systems. These technologies are widely used in
geomorphological studies. Remote sensing and GIS
technologies were used to study the shoreline changes of
Alibag in Raigad district of Maharashtra, India, which lies
between 18° 30’N and 18° 45’ N latitude, and 72° 45’ E and
73° 00’E longitude. IRS-1D LISS III satellite image (2005) and
Survey of India (SOI) toposheet (1971) with the map ID 47
B/14 both on the scale 1: 50,000 were used in the change
detection study. GIS software GRAM++ and ArcView 3.2
were used for the analysis. Total areas of erosion and
accretion along the Alibag coast were found to be 3.81 km2
and 6.5 km2 respectively during the last 34 years (1971 to
2005) Ground-truthing validated the findings of the study.
Anthropogenic activities like land reclamation, increased
human settlements, industrial development, recreational and
tourism activities were responsible for the accretion in these
areas. Erosion was mainly due to natural forces especially in
the eastern side of Korlai where the Kundalika River is
flowing. Anthropogenic activities like dredging and
deforestation were the causes of erosion in other places of
the study area. Shoreline changes resulted in displacement of
coastal population, loss of property, salinisation of land and
water, as well as decrease in fish landings. The study amply
demonstrated the utility of remote sensing and GIS
technologies in monitoring and detection of coastal features.
