Fluvial Geomorphic Analysis Using Remote Sensing Techniques For Detection Of Palaeo Channels And Old Valley In Kharun River, Mahanadi System, C.g., India

The geomorphic characteristics largely determines the behavior of fluvial drainage system of a river catchment. The morphological changes of river tract, channels occurs mainly due to disturbances of equilibrium in fluvial drainage system. In this study the migration and shifting of river tract and geomorphic features of old flood plains has been detected using remote sensing techniques interpretation with limited field checks. The study reveals that the Kharun river of Upper Mahanadi Catchment, at north of Raipur City reaches mature stage and flows over undulating plains and low relief topography. The carrying capacity of Kharun river reduced and bed load of sediments have been deposited as concave – convex loop or bands of one of the meandering channels. The litho contacts of varied sedimentary rock formation causes the meandering and shifting of river channels. The structural trend and features like joints, lineament, fracture, fissures and Topographic ground land scape and slope also governs the river flow alignment in the valleys. The clues regarding palaeo channels and old river valley traces evidenced by reminant of geomorphic features associated with fluvial zones, as it is a dynamic system and changes in channelization depends on existing geomorphic conditions. The palaeo geomorphic features have immense values hydrogeologically since these features acts as controlling factor in management and development of catchment area.
