Latitudes 21º12’39": 21º23’20" North and Longitudes
82º11’22": 82º22’00" East. The district HQ
Mahasamund is situated on S-W boundary of the
watershed. Mahasamund town is located at 65
Kilometers East of the state capital, Raipur. The area
is well connected with National Highway and
Railway with Raipur.
The location and spatial extent of the
Watershed is taken from Toposheet 63K/3 & 63 K/
4. The Naini watershed is a part of National level
Watershed category (as per the Watershed Atlas of
India) 4G2F4. The watershed covers an area of
125.82 sq. km. comprising of 29 villages.
Methodology
The success of the water conservation
measures depends on critical analysis of natural
resources vis-a-vis requirement o water for the
population of the watershed. Therefore a sound
resources database on natural resources such as
Landuse, Hydro-geomorphology, has been prepared
Remote Sensing Data
by using remote sensing technique in which Multi
date satellite imagery of IRS-1C for the years of
2002-2003 on 1:50,000 scale was used for the
preparation of resources maps for watershed area.
False Colour Composite (FCC) of the imagery was
generated and used for better identification of
categories through visual interpretation. Date of
pass, path/row of satellite image data used for the
resources mapping is given in the table.
Landuse Landcover of Study Area
LISS-III standard FCC on 1:50,000 scale for
the identification of different land use / land cover
classes based on image interpretation characteristics.
Using a minimum mappable unit of 3x3 mm and a
broad image interpretation key, which was
developed by Dr. N.C. Gautam, was followed for
mapping. The classification system used for the same
was also a standard one, a 22-fold classification
developed by NRSA. Refer map 1.1
