Tidal influence on downstream fining in gravel-bed rivers

Creator:

Coles, Derron Rafiq

Abstract:

This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

Magma chamber processes over the past 475,000 years at Mount Hood, Oregon : insights from crystal zoning and crystal size distribution studies

Creator:

Darr, Cristina M.

Abstract:

Several different petrological techniques have been applied to lava flows between 200 to 475,000 years old from Mount Hood, Oregon. Mount Hood is unusual, in comparison to nearby Mount St. Helens and Mount Jefferson, in that it has produced relatively homogeneous lava compositions over 475,000 years. Erupted lavas are mostly...

An empirical statistical model relating winds and ocean surface currents : implications for short-term current forecasts

Creator:

Zelenke, Brian Christopher

Abstract:

An empirical statistical model is developed that relates the non-tidal motion of the ocean surface currents off the Oregon coast to forecasts of the coastal winds. The empirical statistical model is then used to produce predictions of the surface currents that are evaluated for their agreement with measured currents. Measurements...
