Geology and geomorphology control suspended sediment yield and modulate increases following timber harvest in temperate headwater streams. Journal of Hydrology In small, high-gradient streams, such obstructions create a stair-step profile that dramatically alters the streams' physical nature (Bilby and Likens ). Upstream of the dam, streams are deeper, current velocities lower, retention of particulate inorganic and organic matter higher, and sub-strate particles smaller. This depositional zone cre-

George G. Ice  Clearcutting has been vilified because of potential effects on water quality and runoff. A Native Forest Network Campaign web site states that clearcutting “ exposes the soil to erosion, water storage capacity is lost, streams or rivers are loaded with sediment, killing ~and~Water~ and maintenance of organic matter processing sites within the benthic community.
The locations and principal roles of woody debris change throughout the river system. In steep headwater streams where logs span the channel, debris creates a stepped longitudinal profile that governs the storage and release of sediment and detritus, a matter (e.g., litterfall and dissolved organic matter).
Terrestrial invertebrates, an additional source of nutrients in small streams, are important to fish (Wipfli ). Terrestrial invertebrates and other organic material transferred from small to larger streams represent a substantial subsidy of nutrients to downstream :// /forestry/frep/extension-notes/ Insecticide use in urban areas results in the detection of these compounds in streams following stormwater runoff at concentrations likely to cause toxicity for stream invertebrates.
In this study, stormwater runoff and streambed sediments were analyzed for 91 pesticides dissolved in water and pesticides on sediment. Detections included 33 pesticides, including insecticides Riparian vegetation in the catchment has diverse distributions.
In areas where phreatic levels are high but rarely inundated, willows (Salix spp., Salix alba), oaks (Quercus pyrenaica), elms (Ulmus minor), and spiny plants (Rubus ulmifolius, Crataegus monogyna, Lonicera spp., Prunus spona and Rosa spp.) upper mountain areas, riparian vegetation is dominated by Betula pendula WATER RESOURCES BULLETIN VOL.

Beschta’ ABSTRACT.: Bedload transport was measwed with two sampler types (vortex tube and Hdey-Smith pressure differential) for three transport in an Oregon coast range.
We studied total mercury (THg) and methylmercury (MeHg) in eight streams, located in Oregon, Wisconsin, and Florida, that span large ranges in climate, landscape characteristics, atmospheric Hg deposition, and water chemistry. While atmospheric deposition was the source of Hg at each site, basin characteristics appeared to mediate this source by providing controls on methylation Beschta, R.L.
Patterns of sediment and organic matter transport in Oregon coast range streams. In Davies, T.R.H. and Pearce, A.J., editors, Erosion and sediment transport in Pacific Rim Steeplands, International Association of Hydrological Sciences Publication The Oregon Coast Range is a dynamic landscape, with steep hillslopes mantled by a thin veneer of soil.
In this and other mountainous regions of the world, debris flows play a major role in routing sediment and organic matter from steep headwater streams and delivering it further down in the channel network. Debris flows also play an important role in shaping the topography of mountain NSAEC Products, Stream Notes.

The study area has a siliceous geology (mainly slate and schist) and the river systems consists predominantly of small to mid-sized coarse substrate-dominated mountain streams and rivers (MKULNV, ). decomposition of organic matter behind a dike reduces surface elevation growth rate, despite sediment accretion, due to subsidence.
An estuary that has never been diked will show a balance between sediment accretion and erosion or subsidence. When a dike is removed from an estuary, sediment inputs generally increase and accretion rates :// Time, space, and episodicity of physical disturbance in streams Daniel Millera,*, Charlie Luceb, Lee Bendac aEarth Systems Institute, WA NW 57th Street, Seattle, WAUSA bBoise Aquatic Sciences Lab, Rocky Mountain Research Station E.
