  Citation × Citation Citation Abstract Copy Title: The effects of hillslope and fluvial processes on particle size of the stream bed at the watershed, reach and within-reach scales in a fifth-order mountain stream Author: Lambert, Beth C. This study addressed the effects of hilislope and fiuvial processes on spatial patterns of stream bed particle size at the watershed, reach and within-reach scales. The study was conducted in Lookout Creek watershed, a fifth-order, 64 km2 basin in the Western Cascades mountains of Oregon. Stream bed particle size was measured at 25 sites on first- through fifth-order streams. Boulder density was measured from the headwaters of the mainstem of Lookout Creek to its mouth, approximately 16 kilometers of stream length. In Lookout Creek watershed, spatial patterns of particle size result from a hierarchy of hydraulic and hilislope controls. At the watershed scale, hydraulic controls explain around 50% of the variation in d50 and d84. Particle size is related to watershed-scale trends in stream power and stream competence. At the reach scale, debris flows and landslides leave a patchy signature on stream bed particle size. Patches of both high and low boulder density are associated with landslides. A peak in density is associated with a February 1996 debris flow. Hydraulic controls are less evident at this scale, although the degree of reach constraint may affect particle size in fourth- and fifth-order Lookout Creek. At the within-reach scale, hydraulic controls are responsible for around 20% of the observed particle size variation. The effects of the largest flood on record at Lookout Creek were documented at 7 sites that had been sampled before the flood. At the watershed scale, a fining in particle size was observed; this is consistent with the hypothesis that Lookout Creek has an armor layer which the flood disturbed. At the within-reach scale, changes in particle size appeared stochastic, and provided little information about the role of hydraulic controls at that scale.

  Citation × Citation Citation Abstract Copy Title: Water over stones : Oregon watershed stories Author: Oberst, Gail D. The 13 personal essays in Water over Stones: Oregon Watershed Stories explore the author's experiences in dozens of Oregon watersheds. Using the genre of the personal essay, the author, a fifth-generation Oregonian and amateur ecologist, writes about her life and family relationships in stories that are saturated with the waters in which they have lived, logged, fished, and died. These stories are no defense of her family's past. but neither are they a condemnation. Rather, these personal essays are an inside look at the conflicts that arise in the author and in her family relationships when she discovers a protective love of her watersheds, marries an environmental scientist and then tries to negotiate her family's values with environmental values attached to her home waters. This negotiation dives deep into personal waters that flow from childhood anger to religious ecstasy. The author's negotiation of these waters demonstrates the personal essay's unique use as a tool for exploring issues that underlie the science of watershed; specifically: people and their relationships to each other and to their waters. These essays are drawn from the author's experiences in watersheds as wild as Lawson Creek in the Kalmiopsis Wilderness, where her family was lost, and as tame as Ash Creek in the Willamette Valley, where she now lives.

  Citation × Citation Citation Abstract Copy Title: Stream channel response to peak flows in a fifth-order mountain watershed Author: Faustini, John M. This investigation explored how the magnitude, style, and frequency of channel adjustments vary spatially and over time within a 5th-order mountain watershed. Historical data sets, including repeated cross section surveys spanning up to 20 years at five sites on 2nd to 5th-order channels and streamflow records spanning up to 50 years, were supplemented by mapping and field reconnaissance activities. The study had two major parts. The first focused on two adjacent, contrasting stream reaches to examine the influence of large woody debris (LWD) on channel morphology and channel response to peak flows in a 3rd-order stream. The upper reach flows through old-growth forest with abundant LWD, while the lower reach was clearcut in 1964-65 and contains little LWD. A 25-year flood in 1996 caused deposition upstream of LWD steps in the old-growth reach alternating with scour between steps, resulting in no net gain or loss of sediment within the reach, while extensive scour and coarsening of the bed occurred in the clearcut reach. These observations suggest that reach-scale channel response was strongly influenced by LWD abundance, but that response at finer scales depends critically on the details of the location and arrangement of LWD. The second part of the study examined the dynamics of channel response to peak flows over two decades, and to two particular large floods during that period, in different portions of the channel network. The cross section data show that the streambed at the study sites is very stable, particularly in lower-order channels. Peak flows that produced detectable change at 90% of cross sections-flows able to cause significant channel adjustments-recur approximately three times as frequently (every 6-7 years) in 4`" to 5`h-order Lookout Creek as in 3rd-order Mack Creek (20-25 years). Flows that produced detectable change at 25% of cross sections are estimated to occur on average every 1.7 to 3.0 years at the study sites. It is estimated that if peak flows of all sizes were increased by only 10% due to anthropogenic impacts (e.g., logging) or climate change, the frequency of peak flows of a magnitude observed to produce significant channel adjustments would increase by approximately 30% in Lookout Creek and 60% in Mack Creek.
