Abstract

Mountain streams exhibit a diversity of channel-reach morphologies formed over a range of fluvial and no fluvial factors. BAGHLAR CATCHMENTs is one of fluvial systems of northern slope of Mishow - Dagh in NORTHWEST OF IRAN that has experienced drastic changes in recent geologic times. RIVER CAPTURE is a stage of evolution in this catchments, whose effects are accompanied with slope instabilities due to tectonic activities in stream channel - reach deformation all of which are studied in this paper. The study includes the investigation of morphology of channel segments based on field studies and available models. Subsequently, four channel - reach types were recognized:Plane - bed, bedrock step - pool, cascade, and cascade - pool. Difference in plane - bed channel characteristics in various segments of catchments, formation of cascade - pool channel and occurring of periodic disturbances in stream flow, deformation of plane - bed bed form to step-pool type in a portion of channel, and formation of cascade reach are among effects of no fluvial factors (river capture and slope instabilities) on channel reach morphology. Such studies will contribute to a better estimation of the impacts that have on channel processes along alluvial rivers, providing fundamental information for land use planning, environmental conservation and sediment disaster control. Finally the investigation of no fluvial factors have been acknowledged in the selection of appropriate sediment entrainment equations for estimating bed load transport rates in mountain streams.
