Spatial and temporal runoff response to snowmelt, and the influence of geomorphology in a headwater catchment, central eastern Cascades, Washington

Creator:: Alley, David
Abstract:: This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

Critique of seven helicopter timber sales with recommendations for improved planning

Creator:: Petaisto, Inga T.
Abstract:: The focus of this study centers around the economic, technical, and environmental effects analysis of seven helicopter timber sales on four different national forests in Oregon and Washington. This paper is a constructive critique of these seven sales based on the author's personal observations and data collected from planning documents,...

SkidPC 2000: a mobility, production, and rut depth simulation program

Creator:: Spong, Ben D.
Abstract:: SkidPC 2000, written in Visual Basic Version 6.0, is an updated version of the 1987 DOS program that calculates the mobility and productivity of ground-based logging vehicles over a ground profile. As in the original program, the user enters the vehicle and operational conditions and the program will calculate the...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

Applications for synthetic rope in logging

Creator:: Leonard, Jared M.
Abstract:: Steel wire rope is used for many logging applications. This material has served the logging industry well in terms of strength, durability, and longevity; Steel wire rope is difficult to use because of properties that make it stiff, heavy; and unyielding. These same properties cause fatigue, exhaustion, and may contribute...

FishXing: evaluation of fish passage culvert model and comparision with Oregon Department of Forestry's compliance with fish passage and peak flow requirements at stream crossings

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...

Overcoming the obstacles of effective photogrammetric mensuration

Creator:: Farnsworth, Blake Templeton
Abstract:: This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography. This report on the pursuit of...

Operating in an uneven-age management prescription

Creator:: Alarid, Steven
Abstract:: Forest managers in recent years have begun to re-examine the possibilities of using uneven-age silvicultural systems in the Oregon Coast Range. This increasing interest is being driven by a variety of forest resource nianagement concerns, including wildlife habitat diversity, visual aesthetics, and long-term sustained yield. In an effort to begin...

Road surface runoff for the Oak Creek watershed: the influence of hillslope and road characteristics

Creator:: Ellingson, Kami S.
Abstract:: Understanding how forest roads interact with hillslope hydrology by intercepting and/or rerouting storm runoff will better enable land managers to reduce erosion related to forest roads. Watershed scale knowledge of how culvert runoff response varies across the landscape would provide valuable information to those individuals designing and maintaining forest road...

Soil compaction and disturbance following a thinning of second-growth Douglas-fir with a cut-to-length and a skyline system in the Oregon Cascades

Creator:: Allen, Marganne Mary
Abstract:: Soil bulk density and disturbance were measured before and after a commercial thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear densimeter was used to measure bulk density at four and eight inches....
