Mega-geomorphology and sedimentation history of parts of the Ganga-Yamuna plains

Abstract

Mega-geomorphological units in parts of the Ganga- Yamuna plains have been mapped using IRS-LISS III remote sensing data. The study highlights the differences in geomorphic setting of this part of the Gangetic plains with that in more eastern parts, and this is manifested in fluvial landforms. A 20 m incised bank section at Kalpi in the Yamuna plains has also been examined and preliminary interpretations about the general stratigraphy are presented. The fluvial sequence manifests several hiatuses in the sedimentation record represented by palaeosol units.
