Morphotectonic Evidences of Neotectonic Activity in the Lower Chambal Valley Region, India

Lower Chambal Valley Region makes western part of the Marginal Gangetic Alluvium Plain (MGAP) that falls in the Flexural Bulge of Central India. Due to thrust loading of Himalaya, there is continues upliftment in the region that is manifested by many geomorphic markers on the alluvium. Previously there is some speculative research work have been done, in this paper a attempt is made to presents a comprehensive work on geomorphic manifestations of Himalayan tectonics on the alluvium, structural and tectonic control on the drainage, gully erosion. In this work Field survey data, CARTOSAT1-DEM Data, topographic maps are used, this data processed, analysed and interpreted using QGIS Software. Study found that alluvium intensely dissected by ravines of Chambal and its tributaries, zigzag meanders show basement lineament control, incised valley up to 50 meters deep, river terraces, different topographic levels, abnormal drainage patterns, palaeocahnnels and cutoff meanders and scarps etc. these geomorphic features are formed due to peripheral bulge upliftment related to Himalayan thrust loading. This paper will elaborate these findings and will be useful in further academic studies and in understanding intense gully erosion problem of the region.
