The characteristics and interactions of the riparian stand, large woody debris (LWD), and channel morphology were examined on five undisturbed, low gradient streams in southeast Alaska. One first-, two ...
Citation -
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 ...
Citation -
Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects ...

5. [Article] Patterns and Impacts of Urban Stream Burial and the Potential for Stream Daylighting in Portland, Oregon
Over the last 150 years, many urban areas have seen streams disappear underground into sewer systems and pipes. Stream burial, the rerouting of open channels to pipes and culverts, has a strong positive ...Citation -
6. [Article] The thermal characteristics of hydrologically intact Type C and E streams in eastern Oregon
Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no ...Citation -
Reach defined analysis concentrated on the water temperature change that occurred in a stream/river segment over the course of one full diurnal cycle. Digital thermistors, data loggers and computer model ...
Citation -
This research investigates the direct and downstream impacts of clearcut harvest units on stream temperature as a part of the Hinkle Creek Paired Watershed Study. The Hinkle Creek watershed is located ...

9. [Article] The influence of environmental and physical factors on the thermal patterns of headwater streams
A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed ...Citation -
10. [Article] Mass erosion occurrence and debris torrent impacts on some streams in the Willamette National Forest
This study focused on extensive soil mass movement occurrence in the Willamette National Forest of western Oregon and on intensive measurements of some physical and biological changes in streams following ...Citation -
Headwater streams are an integral part of the ecological health of the greater stream network as they provide valuable biological habitat, provide upwards to 95% of total in channel flow, while providing ...

12. [Article] Can air temperature be used to project influences of climate change on stream temperature?
To the best of our knowledge, one or more authors of this paper were federal employees when contributing to this work. This is the publisher’s final pdf. The published article is copyrighted by the Institute ...Citation -
13. [Article] Forest road hydrology : the influence of forest roads on stream flow at stream crossings
The management of existing forest road systems is an issue of growing importance and public debate. Roads can alter the hydrologic processes in a watershed especially at stream crossing culverts where ...Citation -
14. [Article] The population dynamics and reproductive strategy of the stream snail Oxytrema silicula (Gould) in relation to stream order
The population dynamics and reproductive strategies of the stream snail Oxytrema silicula were examined in four coastal streams in Oregon representing a small first order stream, a wider third order stream ...Citation -
15. [Article] Effects of elevated temperature on juvenile Coho salmon and benthic invertebrates in model stream communities
Juvenile coho salmon (Oncorhynchus kisutch (Walbaum)) and aquatic invertebrates were subjected to experimentally increased, but naturally fluctuating, temperatures in a model stream channel. Coho of the ...Citation -
The Steamboat Creek basin drains 227 mi² (588 km²) of steep forested terrain into the North Umpqua River of Southwest Oregon, 39 mi (63 km) northeast of Roseburg. Summer base flows for Steamboat Creek ...

17. [Article] AI - Stream Habitat Conditions in Western Oregon, 1999
Abstract -- The physical habitat of a stream forms the template from which the biological community can develop. The structure and complexity of the stream habitat influences the species composition, distribution, ...Citation -
This study is part of the Alsea Basin Logging-Aquatic Resources Study research program. It was initiated to determine the applicability of energy budget theory to stream temperature prediction on small forested ...

20. [Article] Linkages among land use, riparian zones, and uptake and transformation of nitrate in stream ecosystems
Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the ...Citation
