The Rapti river is a major foothills fed tributary of the Ghaghara river in terms of discharge and sediment load. The planform of the Rapti is highly sinuous in the stretch under study. The present work focuses on the fluvial geomorphic features within the valley margin. The study reveals that the floodplain is formed due to lateral migration of channel and associated scroll bars in accordance with unit stream power varying from ~10 Wm-2 to 23 Wm-2 . Further an attempt has also been made to study the hydrometeorological conditions of 2011 monsoon season and its effect on channel instability. Lateral expansion, translation of meander and cut-offs formation are responsible for altering the planform of the channel. Based on the proportion of bar area to channel belt area and channel area, we indentified reach wise aggradational and degradational processes. The shifting distance and direction of central line of Nov.2011 with respect to central line of Feb.2011 were calculated in GIS environment. The general shifting trend was found to be towards SW
