The influence of contemporary forest management on stream nutrient concentrations in an industrialized forest in the Oregon Cascades

Creator:: Meininger, William Scott
Abstract:: The increased demand for wood and fiber from a continually shrinking land base has resulted in the use of intensively managed forest plantations. The concentration of timber production on the most suitable sites allows the world's demand for forest products to be met on less land and enable native forests...

Using in situ turbidity to estimate sediment loads in forested headwater streams : a top-down versus bottom-up approach

Creator:: Meadows, Matthew W.
Abstract:: Suspended sediment and in situ turbidity data from two western Oregon streams, Oak Creek and South Fork Hinkle Creek, were used to estimate annual sediment loads for the 2006 water year (October 1, 2005 to September 30, 2006). Water samples and in situ turbidity observations were taken following the Turbidity...

Sediment production from forest roads in the upper Oak Creek Watershed of the Oregon Coast Range

Creator:: Amann, Joseph R.
Abstract:: Unpaved roads are sources of chronic sediment in forested watersheds. Bare soil on roads is exposed to erosion from rainfall and runoff Published research on sediment production from forest roads focuses primarily on road characteristics. Since water drives the mechanics of sediment transport, hydrologic variables should correlate with sediment production....

Response to Water Protection Rule changes in the Oregon Forest Practices Act : landowner/operator opinions and streamside conditions

Creator:: Hairston, Anne B.
Abstract:: This study assessed implementation of the 1994 Water Protection Rules in the Oregon Forest Practices Act from the perspective of Rule users and post-harvest riparian conditions. A 1993 evaluation found that under the previous rules over half of riparian conifers were removed during harvest, prompting concerns about future sources of...

Uncertainty in forest road hydrologic modeling and catchment scale assessment offorest road sediment yield

Creator:: Surfleet, Christopher G.
Abstract:: The goal of this study was to advance methods for assessment of forest road hydrologic response and sediment yield at a catchment scale. This research looked at the effect of soil depth estimation on the Distributive Hydrology Soil Vegetation Model (DHSVM), assessed the uncertainty and accuracy of hydrologic modeling of...

The influence of contemporary forest harvesting on summer stream temperatures in headwater streams of Hinkle Creek, Oregon

Creator:: Kibler, Kelly Maren
Abstract:: Stream temperature is a water quality parameter that directly influences the quality of aquatic habitat, particularly for cold-water species such as Pacific salmonids. Forest harvesting adjacent to a stream can increase the amount of solar radiation the stream receives, which can elevate stream temperatures and impair aquatic habitat. Oregon Forest...

A physical and chemical characterization of stream water draining three Oregon Coast Range catchments

Creator:: Hale, V. Cody
Abstract:: Few studies have examined both long-term and fine-scale spatial variations in water quality of small streams in the Pacific Northwest. As such, a case study was conducted to determine if current physical and chemical properties of water in three streams located in the Oregon Coast Range differed from historically measured...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...

Scaling hydrologic impacts from road segments to a small watershed

Creator:: Royer, Timothy Adam
Abstract:: The impact of forest roads on the hydrology of forested watersheds has long been studied. While forest roads have been reported to alter storm runoff at the road segment scale, the potential for changes to be detectable at the small watershed scale has been debated. The purpose of this study...
