ABSTRACT: Coastal watersheds differ
from inland by their unique features including proximity to the ocean, weather
and rainfall patterns, drainage system, subsurface aquifer conditions and
geomorphological units. Land use changes and competing needs for water
resources are especially more distinctive to such watersheds. This difference
leads to put forward the Integrated Coastal Zone Management (ICZM), and is deemed
to provide an operational tool for future researchers, developers and policy
makers. Some important attributes necessary for watershed management in terms
of land capability zonation include drainage, altitude, geology and slopes. The
paper incorporates results of representative watershed namely Shringar Tali
watershed. GIS technique was used to generate layers like drainage and springs,
geology, contour, slopes and Digital Elevation Model (DEM), essential for
watershed management. On the basis of interpretation of layers and superimposed
picture obtained, Land Capability Zonation Map (LCZM) was prepared. The scope
for spring sanctuary development, agro-forestry and aquaculture development is
discussed in the paper.
