Creator:: Grizzel, Jeffrey D.
Abstract:: Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...

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....
Resource Type:: Masters Thesis

Creator:: Lombard, Pamela
Abstract:: This study was conducted to determine how the size and orientation of large wood placed in streams in combination with peak flows, substrate and channel gradient affect pool volume, surface area and maximum depth in two coastal Oregon streams. Eighteen Douglas-fir (Pseudotsuga menziesii) logs were placed in each of two...

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:: Duan, Jinfan
Abstract:: This work describes the modeling framework and initial results for CLAWS (Coupled Landscape And Water System), a physically-based, spatially-distributed hydrologicgeomorphic model that has been coupled with a vegetation dynamics simulation. Spatial variability of topography, soil, vegetation, and climate drive a hydrology module that calculates the water budget at given time...

Creator:: Hairston, Anne B.
Abstract:: This study assessed implementation of the 1994 Water Protection Rules in the Oregon Forest Practices Act from the perspective of Rule users and post-harvest riparian conditions. A 1993 evaluation found that under the previous rules over half of riparian conifers were removed during harvest, prompting concerns about future sources of...

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...

Creator:: Dent, Elizabeth F.
Abstract:: Esmond Creek is a tributary to the Siuslaw River located in the Oregon Coast Range. It is 18 km in length and drains a watershed area is 48.9 km². Average channel gradient of the study reach is 0.9%. In 1988 a landslide occurred in the Esmond Creek watershed involving approximately...
