Bedload Sediment Transport and Channel Morphology of a Southeast Alaskan Stream I. INTRODUCTION edload sediment transport in streams is a natural process that removes the relatively coarse-sized products of erosion from the site of weathering and moves them through the fluvial system. bed. Bedload sediment transport ranged from to kghr⁻¹, with peak transport rates occurring during peak streamflow.

Regression relationships were developed between bedload transport, gravel-sized inorganic bedload transport, coarse particulate organic matter transport, two particle size diameter classes (D₅₀ and D₉₀), and stream discharge during the ten by: 1. Duringtransport of bedload sediment and channel morphology were determined at Trap Bay Creek, a third-order stream that drains a square kilometer watershed on Chichagof island in southeast Alaska.

Bedload sediment was sampled for 10 storms: peak flows ranged from to cubic meters per second, and transport rates ranged from 4 to kilograms per hour.

Transport tended to be greater, in terms of amount transported, at the upper riffle for most of the storm events. The opposite was true during the largest storm of the season and a storm which occurred a week later. It may be that bedload sediment is transported past the upper riffle by lesser magnitude events and is temporarily stored in the pool.

We used bedload transport data from to for a total of 64 events, which included a wide range of sediment yields (62 m 3 in to m 3 in ), and two extreme events (J and August 1, ) that we define by the transport of boulder steps and increased subsequent bedload fluxes [Turowski et al., ].Cited by: A zone of bedload convergence therefore occurs between these two bedload-transport paths, which generally coincides with the tidal–fluvial transition in tide-dominated estuaries (Dalrymple et al., ) and (possibly) the mouth bar zone of tide-dominated deltas (Dalrymple et al., ; Dalrymple, b).

Highlights The effect of sediment supply on mountain streams bedload transport was investigated. A field data set composed of values was analysed. Streams connected to active sediment source have higher transport rate efficiencies. Measurements were compared to a bedload transport equation.

An envelope delimiting minimum and maximum transport was by: Headwater streams are the most important sources of water, sediment, nutrients, and organic matter for downstream systems. Timber harvesting and mass movement alter hydrologic, geomorphic and biological processes in stream channels and riparian zones of headwater systems.

In particular, changes in abundance of woody debris and sediment related to timber harvesting and mass movement and the.

SEDIMENT TRANSPORT Much research has been conducted into sediment transport processes and sediment transport rate pre-diction in rivers, mostly in relatively large rivers.suspended sediment, bedload, and saltation.

For considering effects of sediment transport on channel morphology, sediments are more appropriately divided into wash material and bed material (Church, ).
