A numerical simulation model was presented to describe the material cycling along a river with floodplain, in which river continuum concept and flood pulse concept were modelled to be taken into account for considering the energy flow in river ecosystem. Using the discharge and the river channel conditions observed in Yahagi River, the dynamics of organic matter was illustrated. The organic matter entering into the river from terrestrial area is transported under the effects of physical and biochemical processes in each longitudinal segment of the channel. The results of the simulation show that the amount of organic matter transported during floods is about 28% in Segment.2.
