Incipient motion and particle transport in gravel-bed streams

Creator:: Matin, Habib
Abstract:: The incipient motion of sediment particles in gravel-bed rivers is a very important process. It represents the difference between bed stability and bed mobility. A field study was conducted in Oak Creek, Oregon to investigate incipient motion of individual particles in gravel-bed streams. Investigation was also made of the incipient...

Evolution of the Corvallis fault and implications for the Oregon coast range

Creator:: Goldfinger, Chris
Abstract:: The Corvallis fault is a 50 km long northeast-trending structure, part of which defines the boundary between the central Willamette Valley and the east-central Coast Range of Oregon. Previously the fault had been mapped as either a high-angle reverse or normal fault, with the east block down. New gravity data...

Structure and tectonics of the southern Willamette Valley, Oregon

Creator:: Graven, Erik P.
Abstract:: Surface geology, seismic data, petroleum exploratory well data, and water well data have been used to analyze the structural and tectonic history of the southern Willamette Valley. Tertiary strata beneath the southern Willamette Valley appear to have had an early Cascade or Clarno volcanic source to the east by the...

Geology, structure, and tectonic history of the Tualatin Basin, northwestern Oregon

Creator:: Popowski, Thomas Allan
Abstract:: The northwest-trending Neogene Tualatin basin in northwestern Oregon is a pull-apart basin with approximately 750 m of post-middle Miocene structural relief. Gently tilted uplands capped by Columbia River Basalt Group surround the synclinal basin on all sides. Integrated gravity, aeromagnetic, and seismic reflection data indicated that the basin is underlain...

Holocene and latest Pleistocene paleoceanography of the northeast Pacific and its relationship to climate change in the Pacific Northwest

Creator:: Sabin, Ann Louise
Abstract:: Northeast Pacific Ocean sediments were analyzed to determine the past relationship between northeast Pacific sea surface conditions and the climate on the adjacent continent, the Pacific Northwest of North America. Studies of modern ocean-atmosphere interactions demonstrate the significant effect sea surface conditions and atmospheric circulation in the Northeast Pacific Ocean...

Swash zone sediment suspension and transport

Creator:: Puleo, Jack A.
Abstract:: Swash zone processes are of significant importance to foreshore morphologic change. This thesis addresses the importance of the uprush and backwash fluid motions and flow duration effects to the resulting sediment transport. The analysis relates the field observations to well known sediment transport formulations as well as investigates the importance...

Sedimentation of beaver ponds in an Oregon Coast Range stream

Creator:: Ringer, Gina O.
Abstract:: Through the trapping of sediment behind dams, the presence of beaver in a watershed may cause substantial changes to fluvial and geomorphic processes. In an effort to investigate sedimentation patterns in beaver ponds in the Oregon Coast Range, a case study was made of the annual accumulation of sediment in...

Surface-subsurface facies and distribution of the Eocene Cowlitz and Hamlet formations, northwest Oregon

Creator:: Robertson, Christina Lynn
Abstract:: Since 1979, over $114 million of natural gas has been produced at the Mist Gas Field, currently the only commercial gas field in the Pacific Northwest. In the Mist Gas Field, the sandstone-dominated Clark and Wilson member of the upper Eocene Cowlitz Formation is the reservoir and the overlying upper...

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)...
