Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings

Geography Masters Research Papers

The purpose of this paper is to examine the literature from scientific and governmental entities that describes the problems with elevated stream temperatures in the Tualatin basin, the actions being taken to resolve those problems, and to assess whether these actions are meeting the goal of improving salmonid habitat in the basin. Elevated stream temperatures are considered a pollutant under the US Clean Water Act (Clean Water Act 1972, as amended) because increased stream temperatures can be harmful to native aquatic biota, particularly salmonid fish species that have evolved to use cold water (IMST 2004).

Where Do Mount Baker Snoqualmie National Forest Visitors Go And Which Roads Do They Use To Get There? An Analysis Of The Spatial Data From The 2013 Sustainable Roads Workshops, Rebecca J. Mclain, David Banis, Alexa Todd, Mike Psaris

Geography Faculty Publications and Presentations

This report provides an overview of the key patterns that emerged from the spatial analyses of the destination and route data collected during the 2013 Sustainable Roads workshops on the Mount Baker Snoqualmie (MBS) National Forest. We excluded the pilot workshop data from the analyses because a somewhat different process was used to collect the mapped data. The data used in the analysis was collected from 262 participants in eight workshops (Bellingham, Sedro-Woolley, Darrington, Monroe, Everett, Seattle, Issaquah, Enumclaw). During the workshops, participants mapped up to eight destinations of importance to them, and in most cases, also mapped the routes …

Impact Of Soil Moisture–Atmosphere Interactions On Surface Temperature Distribution, Alexis Berg, Benjamin R. Lintner, Kirsten L. Findell, Sergey Malyshev, Paul C. Loikith, Pierre Gentine

Geography Faculty Publications and Presentations

Understanding how different physical processes can shape the probability distribution function (PDF) of surface temperature, in particular the tails of the distribution, is essential for the attribution and projection of future extreme temperature events. In this study, the contribution of soil moisture–atmosphere interactions to surface temperature PDFs is investigated. Soil moisture represents a key variable in the coupling of the land and atmosphere, since it controls the partitioning of available energy between sensible and latent heat flux at the surface. Consequently, soil moisture variability driven by the atmosphere may feed back onto the near-surface climate—in particular, temperature. In this study, …

Near-Surface Internal Melting: A Substantial Mass Loss On Antarctic Dry Valley Glaciers, Matthew J. Hoffman, Andrew G. Fountain, Glen E. Liston

Geology Faculty Publications and Presentations

The McMurdo Dry Valleys, southern Victoria Land, East Antarctica, are a polar desert, and melt from glacial ice is the primary source of water to streams, lakes and associated ecosystems. Previous work found that to adequately model glacier ablation and subsurface ice temperatures with a surface energy-balance model required including the transmission of solar radiation into the ice. Here we investigate the contribution of subsurface melt to the mass balance of (and runoff from) Dry Valley glaciers by including a drainage process in the model and applying the model to three glacier sites using 13years of hourly meteorological data. Model …

The Risks Of The Rose City: Assessing The Social Vulnerability Of Communities To Multiple Environmental Hazards In The Portland Metropolitan Area, Daniel R. Logan

Geography Masters Research Papers

In the past three decades, research in the geography of hazards and disasters has expanded beyond the response to hazard events and incorporated the concepts of preparedness, recovery, and mitigation. These issues require a complete understanding of the vulnerability of places to hazards, not only in regards to hazard characteristics but in regards to social and economic conditions as well. This paper offers a case study in hazard exposure and social vulnerability analysis which incorporates the methodology of two previous studies on the same topics. A geographic information system was used to determine vulnerable areas and populations exposed to five …

The Cully Park Inter-Tribal Gathering Garden: Place-Making Through Indigenous Eco-Cultural Reclamation, Randall Morris

Geography Masters Research Papers

Portland's history and geography are patterned, like any city, by spatial imaginings both utopian and dystopian. This examination of the raw landscape of the city’s nascent garden space in Cully Park is an attempt to research a third manifestation of space, one that might be called heterotopia. This research into the Inter-Tribal Gathering Garden is a search for a more complete accounting of place, one which also acknowledges the variety of non-human agencies (a list which would include streets, planning documents, various plants, historical accounts, and even the consistent boundaries of the space itself) found in all heterogeneous …

The Cost Of Hauling Timber: A Comparison Of Raster- And Vector- Based Travel-Time Estimates In Gis, Sara M. Loreno

Geography Masters Research Papers

The cost of transporting forest products from harvest site to processing facility is a critical indicator of timber project feasibility. In order to accurately assess these timber haul costs, least-cost travel-time estimates among the site and the facility can be estimated using vector- or raster-based GIS methods. This study explores the applicability of both the raster- and vector-techniques within a variety of landscapes, including forested areas where comprehensive transportation data is limited. A comparison between the travel-time estimates derived from both methods was performed on three study sites using real-world data. The comparison also tested the effect of resolution on …

Industrial Decline In An Industrial Sanctuary Portland’S Central Eastside Industrial District, 1981-2014, Allison Jones

Geography Masters Research Papers

This study examines the evolution of the industrial landscape of Portland, Oregon’s Central Eastside Industrial District (CEID) from the initial declaration in 1981 as an ‘industrial sanctuary’ to the present day. The study recreates the historical landscape of 1981, mapping historical land use data from archived Sanborn maps in GIS. This was then compared to the current landscape of 2014, wherein data gathered from field visits, and online, public land use databases was mapped using GIS.

This paper addresses the recent transformation, looking at patterns within the physical and functional realm; and observing how these changes have influenced the character …

Rivers Of Steel: The Economic Development Of Seattle During The Rail Age, 1870-1920, Neil T. Loehlein

Geography Masters Research Papers

The Pacific Northwest experienced massive urban development and growth in population from 1870 to 1920. The railroad was a key factor contributing to the influx of people and expansion of the built environment. The rival port towns around the Washington Territory’s Puget Sound all strove to become the dominant center of trade. As the pattern of railroads expanded, this new mode of transportation would have a significant effect on which ports would prosper and which would languish. This paper will show that the rail network that developed between 1873 and 1893 would come to favor Seattle at a critical point …
