Object Watershed Link Simulation (OWLS)

Creator:: Chen, Huaisheng
Abstract:: Object Watershed Link Simulation (OWLS) is a physically based watershed model. In the OWLS model, a watershed is defined as a three-dimensional object with linkages between cells and their attributes (e.g., area, slope, soil type, etc.). A cell is defined as the linkages of edges and their attributes (e.g., length,...

The Application of Linear Programming for Forest Land Use and Timber Management Planning with Watershed Considerations in Terengganu, Peninsular Malaysia

Creator:: Mat Isa, Ahmad Zainal
Abstract:: The purpose of this paper is to illustrate the use of Linear Programming (LP) and other mathematical procedures to evaluate watershed and perpetuity constraints on forest land use for a selected scenario in Terengganu, Peninsular Malaysia. The paper describes the system of modelling and forecasting estimates of potential timber growth,...

Coarse woody debris in streams of the Drift Creek Basin, Oregon

Creator:: Veldhuisen, Curt N.
Abstract:: This study examined the occurrence of coarse woody debris (i.e., pieces greater than 0.15 m in diameter and 2.0 m in length) in first- through fifth-order streams located within the Drift Creek Basin of the Oregon Coast Range. Nine "tributary reaches" were surveyed to determine how three land management treatments...

Infiltration capacities and surface erodibility associated with forest harvesting activities in the Oregon Cascades

Creator:: Johnson, Michael G.
Abstract:: An infiltration capacity and surface erodibility study was conducted six years after forest harvesting in the Oregon Cascades. A portable rainfall simulator was utilized to obtain field measurements on the Coyote Creek and Hi-15 Watersheds during summer and fall, 1977. Seasonal variations were found to occur in infiltration capacities 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...

Municipal water source turbidities following timber harvest and road construction in western Oregon

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...

Valley fill and channel incision in Meyer's Canyon, northcentral Oregon

Creator:: Peacock, Kathi A.
Abstract:: Meyer's Canyon, a tributary of Bridge Creek in the John Day Basin, is a deeply incised valley fill in northcentral Oregon. The current channel is incised to the Cretaceous and Tertiary bedrock. To determine the precedence of the current incision and the variation and timing of depositional sequences, the sediments...

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...

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...

Undercut streambanks in forested headwater streams of the Oregon coast range

Creator:: Salminen, Edward M.
Abstract:: This study was undertaken to evaluate the occurrence and characteristics of undercut streambanks in forested headwater streams of the Oregon Coast Range. Undercut streambanks and associated reach characteristics were surveyed along 46 sample reaches (each 152 m in length) in 8 streams; all sample reaches occurred in unmanaged forested riparian...
