Description :
This paper examines the floodplain structure in a region of rapid subsidence, neotectonic disturbances, and frequent avulsion of rivers, and appraises the process responsible for the overall evolution of the floodplains. Investigations through remote sensing data and field observations in the interfan between the Gandak and Kosi megafans in the north Bihar plains, indicate that channel migration through avulsion and cut-offs, and extensive overbank flooding are the most important factors controlling the floodplain structure in the study area.
