Abstract:
Rainwater is a free gift of nature for survival of
animal and plant on earth. Unfortunately this resource
is not being utilized properly. Perhaps water is the one
of the inhumanly mismanaged natural resources. This is
evident when one looks into the problem of scarcity of
water experienced by several countries including India.
A time has to come to think about rainwater harvesting
to overcome water scarcity. The catchment selected for
the present study was Thippagondana Halli (T.G.Halli)
catchment, Karnataka state. T.G.Halli catchment has a
geographical area of 1439.47 sq. km and geographically
stretches between 770 12’ and 770 42’ E longitude and
120 50’ and 130 24’ N latitude. The state capital
Bangalore is located at the south eastern boundary of
the catchment. Remote sensing has provided the base
information’s such as, landuse/landcover, soil,
hydrogeomorphology, slope and other aspects. By
integrating all these thematic information’s potential
sites for rainwater harvesting structures were
recommended to conserve soil and water in the study
area.
