California Groundwater Management, Science-Policy Interfaces, And The Legacies Of Artificial Legal Distinctions, David Owen, Alida Cantor, Nell Green Nylen, Thomas Harter, Michael Kiparsky Feb 2019

California Groundwater Management, Science-Policy Interfaces, And The Legacies Of Artificial Legal Distinctions, David Owen, Alida Cantor, Nell Green Nylen, Thomas Harter, Michael Kiparsky

Geography Faculty Publications and Presentations

California water law has traditionally treated groundwater and surface water as separate resources. The 2014 Sustainable Groundwater Management Act (SGMA) broke with this tradition by requiring groundwater managers to avoid significant and unreasonable adverse impacts to beneficial uses of surface water. This paper considers the trajectory of this partial integration of science, law, and resource management policy. Drawing on legal analysis and participatory workshops with subject area experts, we describe the challenges of reconciling the separate legal systems that grew out of an artificial legal distinction between different aspects of the same resource.

Our analysis offers two main contributions. First ...


Putting Rooted Networks Into Practice, Alida Cantor, Elizabeth A. Stoddard, Dianne Rocheleau, Jennifer F. Brewer, Robin Roth, Trevor Birkenholtz, Katherine Foo, Padini Nirmal Oct 2018

Putting Rooted Networks Into Practice, Alida Cantor, Elizabeth A. Stoddard, Dianne Rocheleau, Jennifer F. Brewer, Robin Roth, Trevor Birkenholtz, Katherine Foo, Padini Nirmal

Geography Faculty Publications and Presentations

Rooted networks provide a conceptual framework that embeds network thinking in nature-society geography in order to investigate socio-ecological relations, while emphasizing the place-specific materiality of these relations. This progress report examines how geographers have put the framework into scholarly practice. The conceptual approach has enabled researchers to: 1) articulate the territoriality and materiality of networks as assemblages, which may be simultaneously rooted and mobile; 2) discern diverse types of power that flow through network connections; and 3) conduct analyses that unearth multiply-situated knowledges within networks. Challenges emerge as we seek to integrate the approach more fully with disciplinary traditions, including ...


Pedestrian Pedagogy Of Place: Nurturing An Ecological Consciousness Through Slow Explorations Of The Public Realm, Kevin M. Pozzi Oct 2018

Pedestrian Pedagogy Of Place: Nurturing An Ecological Consciousness Through Slow Explorations Of The Public Realm, Kevin M. Pozzi

Leadership for Sustainability Education Comprehensive Papers

As increasing institutional paralysis and polarization demonstrate, citizens are not engaged or motivated by ecological challenges because they struggle to identify with our catastrophic relationship to nature in this urban, anthropocentric, and climactically-fraught modern era. Rather than focus solely on natural areas as a pathway to ecological consciousness and action, educators can inspire citizens through a “Pedestrian Pedagogy of Place” that brings wonder and enchantment into our urban public realm. Using the principles of sustainability education and place-based education as a framework, this pedagogy recognizes the sidewalk and pedestrian experience as a shared classroom through sensory, awareness-based learning modalities.

Wildfire risk in temperate forests has become a nearly intractable problem that can be characterized as a socioecological “pathology”: that is, a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales. Assessments of wildfire risk could benefit from recognizing and accounting for these interactions in terms of socioecological systems, also known as coupled natural and human systems (CNHS). We characterize the primary social and ecological dimensions of the wildfire risk pathology, paying particular attention to the governance system around wildfire risk, and suggest strategies to mitigate the pathology through innovative planning approaches ...

Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings Nov 2014

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).

Development Of Future Land Cover Change Scenarios In The Metropolitan Fringe, Oregon, U.S., With Stakeholder Involvement, Heejun Chang, Roberrt W. Hoyer

Geography Faculty Publications and Presentations

We describe a future land cover scenario construction process developed under consultation with a group of stakeholders from our study area. We developed a simple geographic information system (GIS) method to modify a land cover dataset and then used qualitative data extracted from the stakeholder storyline to modify it. These identified variables related to our study area’s land use regulation system as the major driver in the placement of new urban growth on the landscape; and the accommodation of new population as the determinant of its growth rate. The outcome was a series of three scenario maps depicting a ...


Top-Down Nationalism In Post-Soviet Kazakhstan, Annie M. Scriven Jan 2013

Top-Down Nationalism In Post-Soviet Kazakhstan, Annie M. Scriven

Geography Masters Research Papers

Kazakhstan was the most multi-ethnic country to emerge from the former Soviet Union and the only one to have its titular ethnicity as a minority. This paper examines the top-down nationalism that has occurred since independence in 1991. The government of Kazakhstan has used elements of the theories of nationalism and territoriality in their effort to build a strong and unified post-Soviet national identity. The role of language, treatment of minorities, changing demographics, and the multi-ethnic nature of Kazakhstan make this a difficult task.

This project tested the accuracy and repeatability of geomorphic stream channel assessments conducted by two different middle school classes from the Walt Morey Middle School in Troutdale, OR and college students from Portland State University in Portland, OR. Each group surveyed the same three cross-sections in Fairview Creek, a tributary to the Lower Columbia River, in order to assess stream channel geometry, discharge, composition of the bed material, and water quality. The three student groups were all able to accurately document the stream channel geometry, including stream width and mean depth, indicating that these data can be successfully collected by ...


Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood Jan 2012

Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood

Dissertations and Theses

This study investigates the hydrologic effects of urbanization in two Portland, Oregon streams through a comparison of three hydrologic metrics. Hydrologic metrics used in this study are the mean annual runoff ratio (Qa), mean seasonal runoff ratio (Qw and Qd), and the fraction of time that streamflow exceeds the mean streamflow during the year (TQmean). Additionally, the relative change in streamflow in response to storm events was examined for two watersheds. For this investigation urban development is represented by two urbanization metrics: percent impervious and road density. Descriptive and inferential statistics were used to evaluate the relationship between the hydrologic ...


Influence Of Wetland Landscape Structure On Duck Nest Success At Malheur National Wildlife Refuge, Oregon, Daniel Robert Craver Jan 2010

Influence Of Wetland Landscape Structure On Duck Nest Success At Malheur National Wildlife Refuge, Oregon, Daniel Robert Craver

Geography Masters Research Papers

The decline of waterfowl populations and their requisite wetland habitats remains a concern. Because migratory bird refuges are often artificial landscapes of actively managed wetlands, and wildlife populations experience their greatest change during the breeding season, refuges should be designed to maximize breeding habitat. While past nest success studies have focused on at-nest variables, new approaches are needed to evaluate the effect of composition and configuration of plant communities at the landscape scale. This study aims to quantify landscape patterns within individual refuge management units to determine influence upon historical nesting success averages of ducks at Malheur National Wildlife Refuge ...


Climatic And Spatial Variations Of Mount Rainier's Glaciers For The Last 12,000 Years, Michael Leslie Hekkers Jan 2010

Climatic And Spatial Variations Of Mount Rainier's Glaciers For The Last 12,000 Years, Michael Leslie Hekkers

Dissertations and Theses

Regional paleoclimatic proxies and current local climate variables and were analyzed to reconstruct paleoglaciers in an effort to assess glacier change On Mount Rainier. Despite the dry and generally warm conditions (sea surface temperatures (SST) -0.15°C to +1.8°C relative to current temperatures), the previously documented McNeeley II advance (10,900 - 9,950 cal yr B.P.) was likely produced by air temperature fluctuations. The average SST record and the terrestrial climate proxies show cooling temperatures with continued dryness between McNeeley II and the Burroughs Mountain advance (3,442 - 2,153 cal yr B.P.). The paleoclimate ...


Examining The Effects Of Climate Change And Urban Development On Water Demand: A Multi-Scale Analysis Of Future Water Demand In Hillsboro, Oregon, Lily House-Peters Jan 2010

Examining The Effects Of Climate Change And Urban Development On Water Demand: A Multi-Scale Analysis Of Future Water Demand In Hillsboro, Oregon, Lily House-Peters

Dissertations and Theses

In the Portland, Oregon, metropolitan area, suburban cities such as Hillsboro are projected to grow as people seek affordable housing near a rapidly growing metropolis. This thesis examines the combined impact of'c1imate change and urban development on both neighborhood and municipal scale residential water demand in Hillsboro, Oregon. I use two models, a surface energy balance model, Local-scale Urban Meteorological Parameterization Scheme (LUMPS), and a system dynamics model, CCDomestic, to investigate changes in residential water demand in the 2040s at two distinct spatial scales, the neighborhood and the municipality. I calibrate and validate each model to the reference period ...


Impacts Of Climate Change And Urban Development On Water Resources In The Tualatin River Basin, Sarah Praskievicz May 2009

Impacts Of Climate Change And Urban Development On Water Resources In The Tualatin River Basin, Sarah Praskievicz

Dissertations and Theses

Potential impacts of climate change on the water resources of the Pacific Northwest of the United States include earlier peak runoff, reduced summer flows, and increased winter flooding. An increase in impervious surfaces, accompanied by urban development, is known to decrease infiltration and increase surface runoff. Alterations of flow amount and pathways can alter water quality through dilution or flushing effects. I used the United States Environmental Protection Agency's Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) modeling system to investigate the relative importance of future climate change and land use change in determining the quantity and quality ...

Western Juniper (Juniperus Occidentalis) Ecology With An Exercise In Remote Sensing Techniques, Elizabeth A. Goralski Aug 2008

Western Juniper (Juniperus Occidentalis) Ecology With An Exercise In Remote Sensing Techniques, Elizabeth A. Goralski

Geography Masters Research Papers

Western juniper (Juniperus occidentalis var. occidentalis) has been expanding its biogeographic range since the mid-1800's, resulting in decreased biodiversity, altered wildlife habitat, increased soil erosion, reduced stream flows and reduced forage production. The direct causes of western juniper aforestation are unclear but appear to be related to altered fire regimes, over grazing, and climatic shifts.

This study seeks to determine how Landsat images combined with Digital Orthoquads (DOQs) can be used to examine the geographic distribution of western juniper. Satellite imagery has yet to be applied to the large scale mapping of western juniper aforestation, resulting in the lack ...


Comparing Pixel- And Object-Based Classification Methods For Determining, Tyler Vick May 2008

Comparing Pixel- And Object-Based Classification Methods For Determining, Tyler Vick

Geography Masters Research Papers

This study analyzes land-cover types in the Gee Creek Watershed of southern Washington using the pixel-based and object-based image analysis approaches. Landsat imagery has traditionally been used for pixel-based classification and change detection in land-cover studies. In recent years, the availability of high-resolution satellite and aerial imagery have enabled for land-cover classification to occur at scales not possible using traditional Landsat imagery. High-resolution aerial imagery of 1 meter or greater has become readily available for free. Yet, commonly found black and white (or panchromatic) aerial imagery is without the multiple spectrum bands found in Landsat imagery, thereby limiting the accuracy ...


The Effects Of Climate Change And Urbanization On The Runoff Of The Rock Creek Basin, Jon J. Franczyk Mar 2008

The Effects Of Climate Change And Urbanization On The Runoff Of The Rock Creek Basin, Jon J. Franczyk

Dissertations and Theses

Climate changes brought on by global warming are expected to have a significant affect on the Pacific Northwest hydrology during the 21st Century. Current research anticipates higher mean annual temperatures and an intensification of the hydrological cycle. This is of particular concern for highly urbanized basins, which are considered more vulnerable to changes in climate. Because the majority of previous studies have addressed the influences of either climate or urban land cover changes on runoff, there is a lack of research investigating the combined effect of these factors. The Rock Creek basin (RCB), located in the Portland, OR, metropolitan ...
