Insect community composition and physico-chemical processes in summer-dry streams of Western Oregon

Creator:: Dieterich, Martin
Abstract:: Seven streams, one of them permanent, were studied in western Oregon, USA. The research was designed to assess the value of summer-dry headwaters for conservation oriented landscape management. Streams were categorized primarily according to exposure (forest versus meadow sites) and secondarily according to flow duration (ephemeral = short-flow versus temporary...

Improving instream flow protection in the West : an evaluation of strategies with an analysis of Oregon's program

Creator:: Root, Ann L.
Abstract:: In the American West keeping water instream to protect fish and wildlife, recreation, and water quality is in direct conflict with traditional water laws. While most western states have established instream flow protection programs, protection has been hindered by the basic tenet of the prior appropriation doctrine, first in time,...

Channel morphology and hydraulic characteristics of torrent-impacted forest streams in the Oregon Coast Range, U.S.A.

Creator:: Kaufmann, Philip Robert
Abstract:: Tracer-derived estimates of hydraulic resistance and transient hydraulic storage were related to measures of pool volume and channel morphometric variability in small streams of the Oregon coast, U.S.A. Fourteen 100 m study reaches in 3 streams were selected to compare channel and hydraulic characteristics in streams representing a time series...

Influences of tillage system, climate, and soils on the demand for topsoil in northcentral Oregon wheat production

Creator:: Hanrahan, Michael S.
Abstract:: Soil erosion research in the fields of agronomy, soils science and mechanics, agricultural engineering, hydrology, climatology, and other scientific disciplines has economic dimensions. In general, measurable and, at times, significant economic effects are associated with the effects of erosion in the other disciplines. Interactions between climate, soils, hydrology, and tillage...

Analysis of streamflow variability in Oregon for regional water quality monitoring programs

Creator:: Saligoe-Simmel, Julia L.
Abstract:: Streamflow variability can provide valuable information for nonpoint source pollution monitoring program planning. The research papers presented in this thesis examine selected properties of streamflow variability in Oregon to advance its application in regional planning of water quality monitoring programs. The products of this research depict Oregon streams by their...

Evaluation of bacterial community indicators of stream sanitary and ecological condition

Creator:: Bracken, Caragwen L.
Abstract:: The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...

Reach scale sampling metrics and longitudinal pattern adjustments of small streams

Creator:: Robison, E. George
Abstract:: Several types of channel morphology measurement parameters used to characterize fish habitat of small streams are refined, developed and evaluated in terms of their accuracy, precision, and sensitivity to disturbance. Data for 74 stream reaches in Oregon and Alaska are used in analysis. Over half the reaches are from a...

Who's in place, who's out of place : examining the politics of natural resource collaboration

Creator:: Cheng, Antony S.
Abstract:: A qualitative research approach composed of three strategies was employed to systematically examine the politics of natural resource collaboration. First, using the Oregon Plan for Salmon and Watersheds as a case study, the behavioral assumptions of natural resource policy instruments enabling collaboration were uncovered and analyzed. Three key assumptions emerge:...

Spatial and temporal dynamics of sediment and wood in headwater streams in the central Oregon Coast Range

Creator:: May, Christine L.
Abstract:: Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...
