Effects of harvest and roads on in-stream wood abundance in the Blue River Basin, western Cascades, Oregon

Creator:: Czarnomski, Nicole M.
Abstract:: Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...

Interacting effects of climate, forest dynamics, landforms, and river regulation on streamflow trends since 1950 : examples from the Willamette Basin and forested headwater sites in the US

Creator:: Hatcher, Kendra L.
Abstract:: Streamflow patterns are a result of the interaction of many factors, including climate, vegetation, geology, and topography. Analyses indicate that streamflow patterns have changed around the United States over the past century, raising questions about the possible role of climate variability as a driver of water yield. This thesis examines...

Effects of Forest Harvest, Floods, and Wildfire on Bedload Export from Headwater Catchments in the H.J. Andrews Experimental Forest, 1957 – 2022

Creator:: Wright, Charles M.
Abstract:: This study examined how annual bedload export volume and bedload characteristics were related to disturbances including logging, floods, debris slides, and wildfires over 48 to 65-year periods in small, steep catchments in conifer forests of the western Cascade Range, Oregon. Bedload – the material rolling, sliding, or saltating along the...

Forestry herbicide use on private forest lands in Lincoln and Benton County Oregon, 1991-1994

Creator:: Godino, John Alessandro
Abstract:: The use of phenoxy herbicides is an established practice in industrial forestry, particularly in the Pacific Northwest. Forestry herbicide use in this region has often been controversial. To better understand the spatial patterns of herbicide use and the potential for human health and environmental impacts, a landscape level perspective is...

Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith S.
Abstract:: Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...

The effects of ownership pattern on forest road networks in western Oregon

Creator:: Freid, Matthew A.
Abstract:: The pattern of ownership imposed on the-forest landscape of Western Oregon defines the boundaries in which differences in jurisdiction, regulation, and land use operate. Road building is controlled by these factors, and in turn has an effect on the cumulative effects of human utilization of the forest. This study examined...

Stream temperature response to partial canopy removal in first and second order streams in the central Oregon Cascades

Creator:: Sullivan, Lawrence
Abstract:: Stream temperature response of first and second order streams to the Blue River Landscape Study (BRLS), an alternative land management strategy based on historic fire regimes, was analyzed in the central Oregon Cascades. The BRLS treatment prescription of a 50% canopy reduction and low intensity burn was applied with a...

Effects of an engineered log jam on flow structure and complexity

Creator:: L'Hommedieu, William J.
Abstract:: The installation of engineered log jams (ELJs) is a common river restoration practice, implemented to modify flow structure and increase hydraulic complexity for the benefit of streambank protection and fish habitat. However, few studies have directly assessed the effects of ELJs on flow structure and complexity. This study presents a...

A study of varying logging practices on stream temperature in the Blue River drainage, Western Oregon Cascades

Creator:: Nicolello, Jon
Abstract:: Three (3) streams with desired similar characteristics, located in the Blue River Watershed in the Central Oregon Cascades, were studied to better understand the impacts of forest harvest on stream temperature and aquatic habitat. Of the 3 designated streams, North Fork Quartz Creek, Blue River Face, and Wolf Mann, only...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...
