A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

A study of the geomorphological processes at the Siltcoos foredune breaching experiment site

Creator:: Hanna, James M.
Abstract:: The focus of this study was to examine and record the physical changes brought about by the breaching of the Siltcoos Foredune. The origin of the dunes and the physical processes that operate there must be considered before effects due to the breach can be studied. A series of field...

Variations in Alsea River flow: implications for Alsea Spit & inlet stability

Creator:: O'Neil, Douglas James
Abstract:: Based in part on previous work by this researcher, variables assumed to play a minor part in the process/ response system examined by the OSU Alsea Bay Hazard Study Team (1985-87)--river input and subsequent variations in hydrology--were more completely analyzed for their range of effects on the stability of Alsea...

A channel stability inventory for two streams on the eastern slopes of the Coast Range, Oregon

Creator:: Sachet, James A.
Abstract:: Stream channel stability for two tributaries of Rock Creek in the Oregon Coast Range is evaluated by application of a Stream Reach Inventory. Stability nomographs are constructed for graphical analysis of erosion potential. Results indicate that channel stability can be classified. One stream is rated as 'Poor' in resistance to...

Side looking airborne radar mapping of wave refraction patterns at the mouth of the Columbia River

Creator:: Bell, James W.
Abstract:: The ocean wave conditions at the mouth of the Columbia River have long proven a hazard to ship navigation. Over 62 major shipwrecks have occurred at, or in the vicinity of the river entrance. The wave pattern is extremely complex, varying seasonally with prevailing winds and river discharge, as well...

Factors affecting animal detection and identification by remote sensing: with special reference to thermal infrared sensors

Creator:: Watkins, Russell L.
Abstract:: Factors affecting animal detection and identification by remote sensing are compiled and described. Habitat preference and animal behavior are shown to be the variables that most influence detection and identification. An analysis of the basis of application of thermal infrared sensors to animal detection covering the principles of infrared radiation...

Estimating streamflow characteristics for micro-hydro sites in northwestern Oregon

Creator:: Lieuwen, Andrew L.
Abstract:: A methodology for estimating streamf low characteristics on Ungaged streams was developed for northwestern Oregon. Basin area and basin area multiplied by the square root of relief were found to be effective independent variables in regression models for estimating the average annual flow, the average daily flood with a two-year...

Monitoring sand dune processes at the Oregon Dunes National Recreation Area : can pre-vegetated conditions be restored?

Creator:: Mitteager, Wendy Ann
Abstract:: The Oregon Dunes National Recreation Area is managed by the Siuslaw Forest division of the United States Forest Service (USFS). This area has gradually been overcome by vegetation since the 1950's, originating with the exotic European Beach Grass (Ammophila arenaria). The invasion of this exotic vegetation has resulted in a...

GIS based riparian area management plans : recommendations to local governments of the Columbia River Estuary Study Taskforce

Creator:: Tolzman, Stephen A.
Abstract:: This paper evaluates Oregon Statewide Planning Goal 5: Natural Resources and Goal 17 Coastal Shorelands, planning programs and makes recommendations for improvement to the Oregon members of the Columbia River Estuary Study Task Force (CREST). CREST is a Council of Governments formed in 1974 which includes the local counties, cities...
