Sediment production and delivery in Pistol River, Oregon and its effects on pool morphology

Creator:

Russell, Periann

Abstract:

Sediment production and delivery in Pacific Northwest coastal streams can have damaging effects on channel morphology and anadromous fish habitat. The research in Pistol River was designed to determine if a link exists between sediment delivery processes and degradation of fish habitat. Objectives of this basin-wide analysis were to: 1)...

Spatial and temporal trends in bed material and channel morphology below a hydroelectric dam complex, Deschutes River, Oregon

Creator:

McClure, Ellen M.

Abstract:

River regulation imposes changes in the supply of sediment and the frequency of competent flows. As a result, impounded rivers often exhibit downstream changes in channel processes, particle size, and morphology. The magnitude of change in competent flow frequency and sediment load together can be used to predict the pattern...

Masters Thesis
Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

Creator:

Stewart, Gregory B.

Abstract:

Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...
