Sediment transport and channel morphology in a small mountain stream in Western Oregon

Creator:: Edwards, Richard Earl
Abstract:: Sediment transport measurements on Flynn Creek, a headwater stream in the Oregon Coast Range, have illustrated the magnitude of fluvial transfer processes, primarily of the bedload component, during a moderate storm runoff season (1979 water year). The total dissolved solids concentration of storm runoff averaged 40 mg/L, and was independent...

Reducing sediment production from forest roads during wet-weather use

Creator:: Toman, Elizabeth Myers
Abstract:: Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

Bedload sediment transport and channel morphology of a southeast Alaskan stream

Creator:: Estep, Margaret A.
Abstract:: This study was conducted at portions of Trap Bay Creek, a medium-sized third-order stream on Chichagof Island, Southeast Alaska, to 1) quantify short-term sediment transport and channel morphology changes, 2) relate measured sediment transport rates to the major hydrologic parameters that appeared to determine the mechanisms of sediment transport, and...

Bed material routing and streambed composition in alluvial channels

Creator:: Jackson, William L. (William Longstreth)
Abstract:: A descriptive model of bed material routing was developed for alluvial streams exhibiting sequences of pools and armored riffles. The model assumes that channel geometry, sediment transport competence and the availability of sediments for transport are all non-uniform in the downstream direction. Bedload transport is described as occurring in two...

An evaluation of a procedure for predicting sediment yield increases from silivicultural activities

Creator:: Larson, Keith R.
Abstract:: Sediment yield increases following timber harvest and road construction were predicted for four Pacific Northwest experimental watersheds. Sediment yields were predicted using a handbook developed by the U.S. Forest Service entitled, "An Approach to Water Resources Evaluation of Non-Point Silvicultural Sources" (WRENS). Predicted sediment yield increases varied from 40 to...

Sediment production from forest roads in the upper Oak Creek Watershed of the Oregon Coast Range

Creator:: Amann, Joseph R.
Abstract:: Unpaved roads are sources of chronic sediment in forested watersheds. Bare soil on roads is exposed to erosion from rainfall and runoff Published research on sediment production from forest roads focuses primarily on road characteristics. Since water drives the mechanics of sediment transport, hydrologic variables should correlate with sediment production....

The suspended sediment regimes of two small streams in Oregon's Coast Range

Creator:: Paustian, Steven Julius
Abstract:: The protection of water quality and the maintenance of productive anadromous fisheries is a primary concern in the Pacific Northwest. Excessive suspended sediment loads is a principle water quality problem on small wildland watersheds in this region (Anderson, 1971; Brown, 1972). Man's activities have been shown to increase sedimentation rates...

Sediment delivery to headwater stream channels following road construction and timber harvest in the Blue Mountains, Oregon

Creator:: Gill, Robert Earl
Abstract:: Many studies have focused on improving our understanding of the effects of timber harvesting activities on soil, water, and fisheries resources. Much of this work has led to the development and widespread use has often resulted in model applications that are outside the bounds in which the models were developed....

Sedimentation of beaver ponds in an Oregon Coast Range stream

Creator:: Ringer, Gina O.
Abstract:: Through the trapping of sediment behind dams, the presence of beaver in a watershed may cause substantial changes to fluvial and geomorphic processes. In an effort to investigate sedimentation patterns in beaver ponds in the Oregon Coast Range, a case study was made of the annual accumulation of sediment in...

Aquatic invertebrate-habitat relationships and stream channel cross section area change in response to streamside management zones in North Central Mississippi

Creator:: Luecker, Terry A.
Abstract:: The southern states lead the country in timber production and are subject to Best Management Practices (BMPs) designed to mediate the effects of forest harvesting on water quality. Small headwater streams on timberland in North Central Mississippi have received little attention with respect to effectiveness of the BMPs designed to...
