| Abstract: | In the present study, an attempt has been made to delineate and characterize the different geomorphic units of Tundiya river
catchment in a part of Lower Maharahstra Metamorphic Plateau, north-eastern part of Nagpur district, Maharashtra. The drainage,
contour and delineated geological units have been overlaid on IRS-ID LISS III satellite imagery (bands 2,3 and 4) in EASI/PACE
analysis system to delineate and characterize different geomorphological units and analysis of their processes based on the
field observations. The study area is basically of metamorphic in origin with different geological formations and is influenced
by the various fluvio-morphological processes. Based on the satellite data analysis, the distinct geomorphological units viz.,
table top summits, structural hills, subdued plateau, linear ridges, shallow, moderate and deeply buried foot slopes, shallow
valley fills and deep valley fills have been delineated and characterized. The information generated from satellite data in
the form of vector layers has been used in GIS to generate geological and geomorphological maps of the study area. The present
study demonstrates that IRS-ID LISS-III data in conjunction with geology, drainage and contour parameters to enable detailed
evaluation of different geomorphological units and analysis of their processes based on the field observations. The delineated
geomorphological units can be utilized for evaluation and management of natural resources and geo-environment on sustainable
basis at river catchment level. |
