An area in the Middle Ganga Basin, lying around Monghyr, Bihar, has been selected for delineation of fluvial palaeofeatures. The investigation is based on aerial photographs LANDSAT MSS and TM data products and ground data. Digital enhancement of LANDSAT MSS and TM data by linear contrast stretching and ratioing has been found to be highly powerful in identification and mapping of subtle fluvial palaeofeatures. Based on the above interpretation, a summary of the fluvial palaeo-history is presented.

Digital enhancement of LANDSAT MSS and TM data by linear contrast stretching and ratioing has been found to be highly powerful in identification and mapping of subtle fluvial palaeofeatures. Based on the above interpretation, a summary of the fluvial palaeo-history is presented.
