Patterns and processes of sediment transport following sediment-filled dam removal in gravel bed rivers

Creator:: Stewart, Gregory B.
Abstract:: Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...

Dam removals and downstream bar-pool morphology

Creator:: Zunka, John Page Purnell
Abstract:: Bar-pool morphology in rivers can provide vital habitat to aquatic species, notably salmonids, which require gravel riffles to bury eggs and pools for hydraulic and cold-water refuge. In some cases, the erosion and subsequent deposition of coarse sediment downstream of a dam removal can modify habitat by inundating bar-pool structure,...

Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

An evaluation of the potential for land use management as an air pollution control measure within the Willamette Valley

Creator:: Vinton, Larry Richard
Abstract:: The rapid population growth and related economic growth of the Willamette Valley has resulted in a significant reduction in air quality over the past several decades. Within the Willamette Valley air ventilation is very poor and therefore the airpo1lutton potential is one of the highest in the United States. There...

A geographic application project utilizing location-allocation computer programs to determine canning facility locations in the Willamette Valley

Creator:: Maddocks, Nicholas Anthony
Abstract:: A Willamette Valley farm cooperative was interested in evaluating locations for their canning facilities based on the criterion of minimizing aggregate distance to their contract farms. This location problem presented an excellent opportunity for a geographic application project as it was characterized by one, a spatial distribution of farms and...

Small mammal assemblages in natural and restored wet prairies: an evaluation of habitat in Oregon's Willamette Valley

Creator:: Slane, Lori B.
Abstract:: This study was conducted to explore differences in diversity and abundance of small mammal populations in natural and restored wet prairies in Oregon's Willamette Valley. Mammals were live-trapped in eight Willamette Valley wet prairies (four natural remnants and four restorations) during the summer of 2000; population abundance estimates for each...

Development of a GIS for the Marys River Watershed for fish and wildlife analysis

Creator:: Callahan, Brady
Abstract:: GIS technology has reached a point where it can be utilized by nonprofessionals in a desktop environment. This paper reviews the implementation of a pilot project for developing a localized-natural resource GIS. The resulting GIS was custom designed to answer questions posed by fish and wildlife biologists who need to...

Geology, flooding & human activities : establishing a hierarchy of influence for controls on historic channel change, Willamette River, Oregon

Creator:: Wallick, Jennifer Rose
Abstract:: Channel evolution and influences of changing floodplain characteristics, heterogenous bank materials, and altered flow regimes were examined along the Willamette River, a large alluvial river in northwestern Oregon. The Willamette River is composed of a series of geomorphically diverse reaches, which have each evolved uniquely in the century following Euro-American...

Transdisciplinary Research in Water Sustainability: What’s in it for an Engaged Researcher-Stakeholder Community?

Creator:: Chan, Samuel, Ferguson, Laura, Santelmann, Mary V., and Tilt, Bryan
Abstract:: This study uses semi-structured interviews and an online survey to explore the structure, challenges and outcomes of a five-year National Science Foundation-funded water scarcity modelling project in the Willamette River Basin of Oregon, USA. The research team chose to facilitate broader impacts by engaging stakeholders from the study’s inception (e.g....
