Remote Sensing and GIS Based Extensive Morphotectonic Analysis of Tapti River Basin, Peninsular India

Abstract

The present study on Morphotectonics of the Tapti basin using remote sensing (RS) data and Geographic Information System (GIS) technique is an important input in deciphering the association between drainage morphometry and tectonics of the area. The basic structural elements like the established faults and other linear features of the study area were identified on the digitally processed remote sensing data and drainage pattern/morphometry was derived from the available Shuttle Radar Topography Mission, Digital Elevation Model (SRTM DEM) (90m) data. The various morphometric characters of the Tapti river basin were studied in detail. The drainage model of this area is a coarse sub-dendritic, trellis, and rectangular. The results of the preliminary morphometric analysis have been correlated with tectonic and seismotectonic characters exhibited by the study area. Overall, the morphometric and morphotectonic analysis revealed the area has periodically experienced tectonic and low order seismic instances.
