Forest vegetation in the upper basin was strongly dependent upon the topography. More specifically, landforms vary in the riparian zone, and the valley floors are mosaics that include active channels, abandoned channels, floodplains, terraces, and alluvial fans Gregory et al. 1991; Sakio 1997. These complex mosaic structures of landforms result from various disturbance regimes in the riparian zone, and the high diversity of microsites and disturbance regimes may promote the coexistence of canopy trees in riparian zones.
