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...

A characterization of road hydrology in the Oregon Coast Range

Creator:: Gilbert, Erin H.
Abstract:: Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...

Hydrology of five forest roads in the Oregon Coast Range

Creator:: Marbet, Christine Erica
Abstract:: Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...

Recruitment trends and physical characteristics of course woody debris in Oregon Coast Range streams

Creator:: Heimann, David C.
Abstract:: This study investigated the long-term consequences of timber stand removal on the recruitment, physical characteristics, and spatial distribution of coarse woody debris in small (second- and third-order) streams of the Oregon Coast Range. A chronosequence of stream-stand systems, ranging from 21- to 140-years since disturbance (YSD), were sampled to determine...

Variations in gravel bed composition of small streams in the Oregon Coast Range

Creator:: Adams, James Neal
Abstract:: A study of the temporal and spatial variability of stream gravel bed composition and the factors affecting the amount of fine sediment within the bed was conducted in the streams of the Oregon Coast Range. Streambed samples were obtained by frozen core techniques and the amount of sediment smaller than...

Debris flow characteristics associated with forest practices in the central Oregon Coast Range

Creator:: May, Christine L.
Abstract:: Debris flows in the Pacific Northwest play a major role in routing wood and sediment stored on hillslopes and in first- through third-order channels to higher order channels and valley floors. Forest practices on steep, unstable slopes and removal of riparian trees along low-order streams can affect the frequency, magnitude,...

Undercut streambanks in forested headwater streams of the Oregon coast range

Creator:: Salminen, Edward M.
Abstract:: This study was undertaken to evaluate the occurrence and characteristics of undercut streambanks in forested headwater streams of the Oregon Coast Range. Undercut streambanks and associated reach characteristics were surveyed along 46 sample reaches (each 152 m in length) in 8 streams; all sample reaches occurred in unmanaged forested riparian...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

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...

Precipitation characteristics for landslide hazard assessment for the central Oregon Coast Range

Creator:: Surfleet, Christopher G.
Abstract:: Precipitation data from 1988-1995 for 13 rain gauges of the Department of Forest Engineering rain gauge network, and a longer precipitation record, 1976-1995, at Mapleton were analyzed. The objectives were to assess the spatial and temporal distribution of precipitation intensity and antecedent precipitation, and understand the role of these characteristics...

Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:: Skaugset, Arne E.
Abstract:: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...
