Seasonal variations [in] tidal dynamics, water quality, and sediments in the Siletz Estuary

Creator:: Rauw, Charles Irving
Abstract:: The Siletz Estuary was studied in 1973 to determine seasonal variations in tidal dynamics, water quality, and sediments. Tidal ranges and times were measured and compared to predicted values at two positions within the bay. Tidal ranges and times were analyzed to determine the dampening and phasing conditions within the...

Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

Energy Related Development in the Columbia River Estuary

Creator:: Smith, Scott E.
Abstract:: The study extends from the mouth of the Columbia River to River Mile 46. It has four elements: an overview of transportation infrastructure, dredging requirements and other constraints and opportunities; identification of potential development sites; description of estuarine impacts; and a review of policy and mitigation strategies. The study in...

The Erosion of Siletz Spit, Oregon

Creator:: Rea, Campbell Cary
Abstract:: Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...

Extrinsic and Intrinsic Factors Associated with Reproductive Success of Caspian Terns (Hydroprogne caspia) at East Sand Island, Columbia River Estuary

Creator:: Bailey, Olivia A.
Abstract:: Declines in wild salmonid (Oncorhynchus spp.) populations in the Columbia River basin have resulted in managers identifying that avian predation on juvenile salmonids is an important limiting factor for salmonid recovery. Caspian Terns (Hydroprogne caspia), particularly those nesting in the Columbia River estuary, were identified as key avian predators that...

The spring 1976 erosion of Siletz Spit, Oregon, with an analysis of the causative wave and tide conditions

Creator:: McKinney, Barbara Ann
Abstract:: During the period 1970-76, Siletz Spit on the mid-Oregon coast has suffered foredune erosion. This erosion is associated with high wave conditions along the coast, produced by intense storms in the North Pacific. During the winter of 1972-73 and during January through March 1976 the erosion was particularly severe. The...

Columbia River Estuary Marina Study

Creator:: Fraser, Michael B.
Abstract:: The goal of this report is to develop information to benefit the planning and operation of marinas within the CREST area, as well as to generate data for use by local Chambers of Commerce, planners, regulatory agencies, Port Authorities and private developers. It is, however, the commercial, charter and recreational...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...

Seasonal variations in tidal dynamics, water quality and sediments in the Siuslaw Estuary

Creator:: Utt, Michael Ernest
Abstract:: Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...
