The expansion of riparian vegetation on floodplain has been reported in many Japanese rivers, and it would be necessary to understand vegetation dynamics for both flood protection and ecological conservation. In this study, a numerical simulation model was presented to describe river-bed evolution and vegetation dynamics with interspecific competition and expansion of riparian vegetation. The numerical simulation was performed under conditions at the downstream reach of the Yahagi river. The results of the simulation show that the present simulation model can predict the long term trend of vegetation coverage and the rates of immigration and destruction fairly well.
