Abstract:: Time trends in flow and channel characteristics were evaluated for the Middle Fork Willamette (MFW) River, which drains a 668 km2 forested watershed in the Cascade Mountains of western Oregon. Timber production is the primary land use in the watershed. Analysis of precipitation and peak flow data from 1959 to...

Abstract:: 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 debris torrents. Debris torrents are a rapid movement of water-charged debris confined to steep headwater channels. The frequency (events/ha/yr) of...

Abstract:: An 18-year record of nitrate (NO₃), orthophosphate, total nitrogen and total phosphorus in four streams of the Bull Run watershed, Oregon, was examined to determine its precision and time resolution. Of these four species, only NO₃ was found to be known to a sufficient level of detail for modeling and...
