Geomatic based soil and geomorphological classification of kumbakonam town, thanjavur district, tamilnadu

In the present study, an attempt has been made to classify the different soil and geomorphic units of Kumbakonam town Thanjavur district, Tamilnadu. The drainage, contour and delineated geological units have been overlaid on IRS-ID LISS III satellite imagery (bands 2, 3 and 4) the system to delineate and characterize different geomorphological units and analysis of their processes based on the field observations. The study area is basically of sedimentary in origin with different geomorphological formations and is influenced by the various processes. Based on the satellite data analysis, the distinct geomorphological units viz., alluvial plain and deltaic plain 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 soil and geomorphological maps of the study area. The present study demonstrates that IRS-ID LISS-III data in conjunction with geomorphology, soil, river and drainage and 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 fiver catchment level.
