Geomorphic Evolution of Chambal River Origin in Madhya Pradesh using Remote Sensing and GIS

Pradeepika Kaushik, Ghosh P.

Abstract


The Fluvial geomorphology of Chambal River basin is so vast in terminology; therefore remote sensing and GIS application and technique to analyzing the whole Chambal geomorphology in interval of space and time has been used. Chambal River is a perennial river and carries large quantity of water and sediment load to transportation. Chambal River is famous for the past prehistoric and as unpolluted river. Chambal origin considered from the Janapav valley (Janapav Shiv Temple) at Malwa ridge surrounded by Manpur Reserve Forest, Madhya Pradesh, India. The source of Chambal water is considered from seepage of groundwater from the Basaltic columnar joint rock (Malwa Ridge) where the water flows from the weak columnar joints of Basalts and follows gradient slop facing in Northward direction. Chambal River has Deccan trap Basalt as river bedded rock, Mesozoic age formation with dendritic drainage pattern at Malwa region. Chambal River origin lies at an elevation of 840.6 meter with Latitude 22027′36.5″N and Longitude 75041′14.4″E (source by: ground truth field data). Physiographically the area to the North of Chambal is characterized by moderately dissected plateau and formed undulating topography. However, to determine the changes in flow, meandering, and geomorphic landforms development in the Chambal river origin, primarily the toposheet no 46N, 46M and Landsat imagery ETM+ data are used for geomorphic evolution maps and digitization and georeferencing has done by using ArcGIS v10 software. Identification of geomorphological landforms with their specific geomorphological processes either erosional or depositional in the fluvial system of the Chambal River will certainly help in assessing the environmental and hydrological problems in this Malwa region.
