Sediment reservoir dynamics on steepland valley floors : influence of network structure and effects of inherited ages

Creator:

Frueh, Walter Terry

Abstract:

Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...

Spatial and temporal dynamics of sediment and wood in headwater streams in the central Oregon Coast Range

Creator:

May, Christine L.

Abstract:

Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...
