Dam removals and downstream bar-pool morphology

Creator:

Zunka, John Page Purnell

Abstract:

Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...

Sediment transfer and storage in headwater basins of the Oregon Coast Range : transit times from 14C dated deposits

Creator:

Underwood, Emily F.

Abstract:

In steep headwater basins of the Oregon Coast Range (OCR), debris flows episodically deliver material from low-order tributary basins to larger catchments. Much of this material is stored in valleys and gradually removed by fluvial processes. Quantifying the transfer of material from hillslopes to mainstem channels is essential in understanding...
