Creator:: Ursitti, Victoria L.
Abstract:: Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

Creator:: Scott, Larissa E.
Abstract:: Salmonid populations in the Pacific Northwest are at historic lows and many populations continue to decline. Previous studies have linked salmonid declines to land use through degradation of in-stream physical habitat, but few of these studies have taken geology into consideration. This study relates habitat parameters known to be important...

Creator:: May, Christine L.
Abstract:: Channels that were scoured to bedrock by debris flows provided unique opportunities to calculate the rate of sediment and wood accumulation, to make inferences about processes associated with input and transport of sediment, and to gain insight into the temporal succession of channel morphology following disturbance. In an intensive investigation...

Creator:: Frissell, Christopher A.
Abstract:: Classification of Streams and stream habitats is useful for research involving establishment of monitoring stations, determining local impacts of land use practices, generalization from site-specific data, and assessment of basin-wide, cumulative impacts of human activities on streams and their biota. This thesis presents a framework for a hierarchical classification system,...

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Creator:: Vest, Sarah B.
Abstract:: Slow moving earthflows (0.1 15 m/yr.) may constrict valley floors and directly impinge on stream channels. Earthflows that move laterally into channels deliver organic and inorganic material to the stream from the earthflow toe. If the amount and particle size of this material is too large to be removed by...
