Abstract :

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