The Cougar, The Tick, and Human Wellbeing: The Social, Economic, and Ecological Valuations of Living with Cougars in Oregon.

Creator:: Miller, Allyson
Abstract:: The overarching objective of this paper is to identify how the three tiers of human well-being (i.e., economics, ecosystems, and social) are linked to healthy landscapes and a species-rich ecosystem mediated by healthy cougar populations. Does the cougar help mitigate Oregon’s Lyme disease, chronic wasting disease (CWD), or elements of...

Channel morphology and hydraulic characteristics of torrent-impacted forest streams in the Oregon Coast Range, U.S.A.

Creator:: Kaufmann, Philip Robert
Abstract:: Tracer-derived estimates of hydraulic resistance and transient hydraulic storage were related to measures of pool volume and channel morphometric variability in small streams of the Oregon coast, U.S.A. Fourteen 100 m study reaches in 3 streams were selected to compare channel and hydraulic characteristics in streams representing a time series...

Physical dimensions and hydrologic effects of beaver ponds on Kuiu Island in southeast Alaska

Creator:: Beedle, David L.
Abstract:: Dimensional characteristics of 44 beaver dams and ponds on Kuiu Island in Southeast Alaska were determined to evaluate the hydrologic effects of these structures on peak flows. The study area consisted of low gradient, incised streams in broad U-shaped valleys. Pond routing simulations were conducted using four return intervals (2-,...

Bed material routing and streambed composition in alluvial channels

Creator:: Jackson, William L. (William Longstreth)
Abstract:: A descriptive model of bed material routing was developed for alluvial streams exhibiting sequences of pools and armored riffles. The model assumes that channel geometry, sediment transport competence and the availability of sediments for transport are all non-uniform in the downstream direction. Bedload transport is described as occurring in two...

Sediment transport and channel morphology in a small mountain stream in Western Oregon

Creator:: Edwards, Richard Earl
Abstract:: Sediment transport measurements on Flynn Creek, a headwater stream in the Oregon Coast Range, have illustrated the magnitude of fluvial transfer processes, primarily of the bedload component, during a moderate storm runoff season (1979 water year). The total dissolved solids concentration of storm runoff averaged 40 mg/L, and was independent...

Summertime stream temperatures in the North and South Forks of the Sprague River, south central Oregon

Creator:: Friedrichsen, Paul T.
Abstract:: The Upper Sprague River Watershed (North and South Forks of the Sprague River) in south central Oregon provides important habitat for salmonid species, including native bull trout (Salvelinus confluentus) and redband trout (Oncorhynchus mykiss ssp.). Concern over the loss of viable habitat for these species has increased due to reductions...

Summer stream temperatures and channel characteristics of a southwestern Oregon coastal stream

Creator:: McSwain, Michelle D.
Abstract:: The Elk River Basin drains 93 sq ml of steep forested terrain on the west side of the Klamath Mountains in Southwest Oregon. This river and its tributaries support a diverse and abundant population of anadromous fish; a hatchery located at river mile 13 (km 21) supplements these native populations....

Influence of hillslope and instream processes on channel morphology of Esmond Creek in the Oregon Coast Range

Creator:: Dent, Elizabeth F.
Abstract:: Esmond Creek is a tributary to the Siuslaw River located in the Oregon Coast Range. It is 18 km in length and drains a watershed area is 48.9 km². Average channel gradient of the study reach is 0.9%. In 1988 a landslide occurred in the Esmond Creek watershed involving approximately...

Hydrology and delineation in four wetlands in the Oregon Cascades

Creator:: MacLeod, Norman A.
Abstract:: Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

Object Watershed Link Simulation (OWLS)

Creator:: Chen, Huaisheng
Abstract:: Object Watershed Link Simulation (OWLS) is a physically based watershed model. In the OWLS model, a watershed is defined as a three-dimensional object with linkages between cells and their attributes (e.g., area, slope, soil type, etc.). A cell is defined as the linkages of edges and their attributes (e.g., length,...
