Abstract: The Rapti River is the most important left-bank tributary of the Ghaghra. The Rapti rises south of a prominent E-W ridgeline midway between the western Dhaulagiri Himalaya and the Mahabharat Range in Nepal at an elevation of about 3048 m. The Dundwa range, a subrange of the Shiwaliks in western Nepal, diverts the Rapti for some 100 km west before the river resumes its southward course towards the Ganga. After flowing through Nepal, it enters eastern Uttar Pradesh in Chanda Pargana, east of the Kundwa village of Bahraich district. The flood waters of the river Rapti are being controlled by the Rapti Barrage. This is situated upstream of the Bhinga site in the district of Shravasti and is maintained by the state government. The Rapti River Basin is part of the middle Ganga plain. It is fed by numerous tributaries and affluents that drop vertically down into Rapti from Shiwalik and its foothills. The basin is a homogenous accretional plain of older and newer alluvial deposits. Like in other tropical monsoon areas, seasonal rainfall causes inundation, floods, water logging, and severe erosion as well as large scale overbank deposition in the Rapti river basin also.
