In order to restore natural vegetation in riverbed excavation work on low water channel of The Inagawa River, we preserved the plane form, made gentle slopes and backfilled the surface soil during the construction work. In two years after the construction work, on the backfilling zone, we confirmed: diverse vegetation were widely restored corresponding to the frequency of inundation; the area of native plant communities increased, while of naturalized plant communities decreased; threatened species appeared. Thus, it was shown that these methods were effective to restore the natural floodplain vegetation.
