régions. Further, there is an increase in demand on Coastal régions in the
recent years for shipping, setting up of industries, developing récréation
centers, land réclamation and utilizing marine resources of various kinds.
The exploration of natural living and non-living resources in the océan has
necessitated construction of a variety of structures like jetties, dykes, seawalls, groins, platforms, pipelines, etc. which are linked to the economy of
the Coastal States and ultimately to the national economy.
The west coast of India is characterised by
(i) Stretches from Rann of Katch to Kanyakumari as a narrow strip
between Arabian Sea and the Western Ghats.
(ii) It has a wider continental shelf
(iii) Lagoons and estuaries are common
(iv) Submerging coast and less attacked by cyclones
(v) Expérience both longshore as well as cross shore sédiment movement
and certain stretches being stable.
The east coast of India is characterised by
(vi) Stretches from Kanyakumari to Sunderbans as a relatively broader
(than western coast) between Eastern Ghats and the Bay of Bengal.
(vii) The continental shelf is narrow compared to the west coast.
(viii) The coast expériences a subtropical monsoonal climate with an
annual rainfall of 1600-1800 mm and severe cyclonic storms.
(ix) Deltas are common.
(x) Most of the major rivers flow into Bay of Bengal leading to a large
imbalance in the sédiment supply along the coast.
(xi) Longshore sédiment transport is dominant.
(xii) Is an emergent coast and more frequented by cyclones.
A considérable portion of the India’s coast is affected by Coastal érosion,
a common phenomenon, by which, a substantial portion of land is taken
away by the sea. The causes of Coastal érosion include that of both natural
and manmade. The Indian Coastal zone has corne under tremendous pressure due to high population density, industries, tourism, fishing etc. Hence,
there is a need to establish the conceptual framework to predict the shoreline and morphological changes for effective usage and protection of Coastal
