Seasonal snowcover dynamics beneath boreal forest canopies

Creator:: Link, Timothy E.
Abstract:: The accurate simulation of snowpack deposition and ablation beneath forested areas is confounded by the fact that the vegetation canopy strongly affects the snow surface energy balance. The canopy alters the radiation balance of the snowcover, and reduces the wind speed at the snow surface. Data collected as part of...

Entrainment, transport, and deposition of large woody debris in streams : results from a series of flume experiments

Creator:: Braudrick, Christian A.
Abstract:: Although there has been extensive research on the geomorphic and ecologic role of large woody debris (LWD) in streams, the dynamics of LWD in streams are poorly known due to various measurement difficulties during floods. In this thesis I present the results of two flume experiments on the dynamics of...

Hydrologic integration of forest roads with stream networks in two basins, western Cascades, Oregon

Creator:: Wemple, Beverly C.
Abstract:: This study assessed how logging-access roads may have contributed to observed historical increases in peak discharges associated with small and large logged basins in the western Cascades of Oregon. The study was conducted on the Lookout Creek (62km²) and the upper Blue River (118km²) basins. Potential road effects on hydrology...

A review and assessment of network concepts and their applications in geography and related disciplines

Creator:: Versluis, Anna J.
Abstract:: Networks are a structure common to many disciplines. Research on networks has taken different forms in domains such as graph theory, sociology, vascular networks, small-world networks, geomorphology, ecology, evolution and engineering. Networks may be modeled as non-spatial networks (unvalued graphs), which contain only topological information, or as spatial networks (valued...

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...

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...

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...

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...

The use of ecological principles for riparian zone management in four forest planning documents

Creator:: Sinton, Diana Stuart
Abstract:: The purpose of this paper is to evaluate the extent to which ecological principles were used in four documents of differing scope and intent, that address management of forest resources and riparian zones in three National Forests of the Pacific Northwest. We use the phrase "ecological principles" in a very...

Habitat quality and biotic integrity in mountain streams of East Maui, Hawaii

Creator:: Carter, H. Jamieson
Abstract:: Hawaiian streams are valued for environmental, cultural, and aesthetic qualities. Windward streams in East Maui, Hawaii are diverted to irrigate crops in central portions of the island. Diversions typically remove 100% of the base flow and leave downstream reaches dry most of the year. Ground water seeps and springs contribute...
