Rivers are characterized by a continuum of morphological diversity. River geomorphic
units also based on their setting in channel and valley divide to four parts, including
channel bed morphology, various mid channels, bank-attached and floodplain features.
Two primary channel-reach are recognized; bedrock and alluvium that their
features including: fall, pothole, rapid, cascade, step-pool, plane bed (run), pool-riffle
and sand ripple-dune. This paper provides a review of previous researches in river
geomorphic units that samples and features produced from northern catchments of
central Alborz. The examination these river geomorphic units provide a simply
understanding of water and sediment transport regime and river behavior.
