Creator:: Bord, Andrea J.
Abstract:: A one-mile section of a newly constructed forest road in Northwest Oregon was analyzed for various aspects of subgrade and surface strength and their association with the formation of ruts during the first hauling season. Field and laboratory tests were completed on the road and the road materials to determine...

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...

Creator:: Morrissette, Brett A.
Abstract:: FishXing (fish crossing), a computer aided stream crossing culvert model designed to analyze fish passage through culverts was compared with results of an Oregon Department of Forestry fish passage monitoring report. FishXing was created at Humboldt State University through sponsorship from the US Forest Service, USDA, Stream Team, Six Rivers...

Creator:: Smith, Danielle D.
Abstract:: The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...

Creator:: Martinez Ben, Jesus
Abstract:: A set of 119 study trees was identified in a 65 year-old Douglas-fir stand after a thinning operation conducted seven years ago using pre-planned skid trails and groundbased machinery. Some of the trails were tilled using a winged subsoiler after this operation in order to alleviate the effect of compaction...

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Creator:: Smith, Russell S.
Abstract:: A study was conducted to investigate the influence of root reinforcements on soil strength and the initiation of static liquefaction in forest soils. The design and operation was developed of an apparatus capable of modeling rainfall-induced shallow hill-slope failures that also permitted observation of the soil volume change tendencies at...

Creator:: McGuire, Kevin J.
Abstract:: The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...
