Climatic and physiographic controls on peakflow generation in the western Cascades, Oregon

Creator:

Perkins, Reed

Abstract:

Despite the importance of rain and snowmelt in causing peakflows in the Pacific Northwest, the interactive effects of a snowpack and watershed physiography on streamflow are largely undocumented. This study investigated the influence of soil and snowpack moisture on peakflow hydrograph shape in three small (< 60 ha) control sub-watersheds...

Frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon

Creator:

Fassnacht, Heidi

Abstract:

A first-order approximation is made of the frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon with implications for salmonid spawning habitat. Field measurements of channel hydraulics, geometry, and particle size were combined with one-dimensional hydraulic and bedload transport models to determine...
