Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith 2016 University of Nottingham

Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith

Connie P. Ozawa

Blue-Green Infrastructure (BGI) and Sustainable Drainage Systems (SuDS) are increasingly recognised as vital components of urban flood risk management. However, uncertainty regarding their hydrologic performance and lack of confidence concerning their public acceptability create concerns and challenges that limit their widespread adoption. This paper investigates barriers to implementation of BGI in Portland, Oregon, using the Relevant Dominant Uncertainty (RDU) approach. Two types of RDU are identified: scientific RDUs related to physical processes that affect infrastructure performance and service provision, and socio-political RDUs that reflect a lack of confidence in socio-political structures and public preferences for BGI. We find that socio-political ...

Land Cover Data For The Mississippi-Alabama Barrier Islands, 2010-2011, Gregory A. Carter, Carlton P. Anderson, Kelly L. Lucas, Nathan L. Hopper

Land Cover Data for the Mississippi-Alabama Barrier Islands, 2010-2011

Land cover on the Mississippi-Alabama barrier islands was surveyed in 2010-2011 as part of continuing research on island geomorphic and vegetation dynamics following the 2005 impact of Hurricane Katrina. Results of the survey include sub-meter GPS location, a listing of dominant vegetation species and field photographs recorded at 375 sampling locations distributed among Cat, West Ship, East Ship, Horn, Sand, Petit Bois and West Dauphin Islands. The survey was conducted in a period of intensive remote sensing data acquisition over the northern Gulf of Mexico by federal, state and commercial organizations in response to the 2010 Macondo Well (Deepwater Horizon ...


Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick 2016 Portland State University

Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick

Meg Merrick

Until recently, few have questioned the notion that the separation of uses in land use zoning is inherently correct. Many observers of the city are now suggesting that zoning, as it has been practiced in this country over the last 80 years, has created cities that are fractured and function poorly. Others propose that zoning should be reconsidered as a remedy for urban dysfunction. They suggest that the whole notion of zoning be rethought.

The purpose of this study is to uncover some of the underlying rationales and methodologies that set the model for zoning. This study examines the rationales ...


Modeling Vegetation Mosaics In Sub-Alpine Tasmania Under Various Fire Regimes, Gabriel I. Yospin, Samuel W. Wood, Andres Holz, David M.J.S. Bowman, Robert E. Keane, Cathy Whitlock 2016 Montana State University-Bozeman

Modeling Vegetation Mosaics In Sub-Alpine Tasmania Under Various Fire Regimes, Gabriel I. Yospin, Samuel W. Wood, Andres Holz, David M.J.S. Bowman, Robert E. Keane, Cathy Whitlock

Andres Holz

Western Tasmania, Australia contains some of the highest levels of biological endemism of any temperate region in the world, including vegetation types that are conservation priorities: fire-sensitive rainforest dominated by endemic conifer species in the genus Athrotaxis; and fire-tolerant buttongrass moorlands. Current management focuses on fire suppression, but increasingly there are calls for the use of prescribed fire in flammable vegetation types to manage these ecosystems. The long-term effects of climate and alternative management strategies on the vegetated landscape are unknown. To help identify controls over successional trajectories, we parameterized a spatially explicit landscape-scale model of vegetation and fire (FireBGCv2 ...

Geopolitical Implications Of The Sino-Japanese East China Sea Dispute For The U.S., Bert Chapman 2016 Purdue University

Geopolitical Implications Of The Sino-Japanese East China Sea Dispute For The U.S., Bert Chapman

Libraries Faculty and Staff Scholarship and Research

Much analysis on Asian strategic challenges facing the U.S. has justifiably emphasized the South China Sea (SCS). This has also been reflected in 2016 presidential campaign debate on the SCS as an emerging area of U.S. foreign and national security policy concern. The East China Sea (ECS) is at least as important for the strategic interests of the U.S. and its allies given the tension between China and Japan over the Senkaku/Diaoyu islands, potential energy resources in this body of water, increasing defense spending by adjacent geographic powers, the area’s importance as a maritime international ...


The Best "Lied" Plans: Engaging Undergraduate Participation In Fieldwork, Andrew Bach 2016 Western Washington University

The Best "Lied" Plans: Engaging Undergraduate Participation In Fieldwork, Andrew Bach

Andrew Bach

This paper describes a field project from an introductory soils course taught in spring 2001. Looking at soils in the field is a necessity, since the physical details of soils cannot be readily reproduced in a class or lab setting.Convincing students that crawling into a muddy hole will help them learn does not always work. So I conceived a plan to inspire the class about looking at soil in the field. I used geography as a starting point, by selecting an extraordinary environmental setting for the field project. Then I fully developed a research project for the class, including ...


Natural History Of The Ahlstrom’S And Roose’S Prairies, Olympic National Park, Washington, Andrew Bach, Dave Conca 2016 Western Washington University

Natural History Of The Ahlstrom’S And Roose’S Prairies, Olympic National Park, Washington, Andrew Bach, Dave Conca

Andrew Bach

The objective of this research is to evaluate the wetland and forest dynamics in and around the Ozette Prairies to identify their origin and history since the Last Ice Age. The Ozette Prairies are treeless areas, dominated by unique associations of understory species in an otherwise heavily forested region. The prairies are historically (pre-European) persistent elements of the landscape in a region where the climate promotes forest growth. Presently, the prairies are undergoing encroachment by the surrounding forest. The patchy character of the vegetation attests to centuries, or more, of climate change, expansion and demise of forest populations and changing ...


Aboriginal Tourism As Sustainable Social-Environmental Enterprise (Ssee): A Tlingit Case Study From Southeast Alaska, Paphaphit Wanasuk, Thomas F. Thornton 2016 University of Nottingham

Aboriginal Tourism As Sustainable Social-Environmental Enterprise (Ssee): A Tlingit Case Study From Southeast Alaska, Paphaphit Wanasuk, Thomas F. Thornton

The International Indigenous Policy Journal

The Tlingit Aboriginal tourism enterprise named Icy Strait Point in Hoonah, Southeast Alaska is used as a case study to develop the new concept of Sustainable Social-Environmental Enterprise (SSEE). SSEE is defined as an innovative enterprise that has dynamic operational strategies while still maintaining its corporate core values and integrating social, environmental, cultural, economic and political (SECEP) sustainabilities in its operations. The SSEE framework assesses enterprises according to five domains of sustainability: social, environmental, cultural, economic, and political. Applying this framework, we find that while social, economic, and cultural sustainability goals have been achieved in a relatively short time by ...


Aquifer Vulnerability Modeling In New Jersey Through The Use Of Modified Drastic Methodology, Clement Uduk, Tanja Hopmans 2016 Portland State University

Aquifer Vulnerability Modeling In New Jersey Through The Use Of Modified Drastic Methodology, Clement Uduk, Tanja Hopmans

Student Research Symposium

Due to the global average increase in temperature over the last 50 years, sea levels have been rising and making coastal aquifers more susceptible to saltwater intrusion. The average rate of sea level rise has increased from 2 mm/year to 3.5 mm/year during the twentieth century. The state of New Jersey is not only densely populated but the development along coastlines makes inundation a potential serious threat. New Jersey is diverse in aquifer types, in addition to the types of water bodies surrounding New Jersey, and makes for an interesting case study for groundwater vulnerability. The EPA ...


Dating Late Quaternary Alluvial Fills In The Platte River Valley Using Optically Stimulated Luminescence Dating, Jacob C. Bruihler 2016 University of Nebraska - Lincoln

Dating Late Quaternary Alluvial Fills In The Platte River Valley Using Optically Stimulated Luminescence Dating, Jacob C. Bruihler

Theses and Dissertations in Geography

Alluvial fills underlying the Platte River Valley in Nebraska record the geologic history of the Platte River in the late Quaternary. This study investigated the alluvium underlying the valley near the cities of North Platte and Kearney, Nebraska. Data obtained from sediment cores drilled in the alluvial deposits was used to investigate the changes in Platte River dynamics on a glacial – interglacial timescale. Optically Stimulated Luminescence (OSL) dating was used to determine burial ages of recovered sediments and to quantify the thicknesses of the late Pleistocene and Holocene alluvial fills at each study area. Our geochronology depicts considerable differences in ...


Relationship Between Lidar-Derived Canopy Layering And Rainfall Redistribution In Forests Varies With Scale, Daniel Cirincione 2016 Georgia Southern University

Relationship Between Lidar-Derived Canopy Layering And Rainfall Redistribution In Forests Varies With Scale, Daniel Cirincione

Georgia Southern University Research Symposium

Forest canopy can reduce precipitation reaching the ground by up to 50% through interception, storage, and evaporation of droplets from leaf and bark surfaces. This process, called "interception loss," impacts runoff, recharge, flood flashiness, erosion, etc., and cost of stormwater management. It is not well understood how canopy structure affects interception loss, particularly in urban forests. This research addresses this issue by monitoring interception loss variables for a common south eastern US tree species (slash pine) across a natural-to-urban gradient in forest structure. This study considers three different sites to obtain the natural-to-urban gradient. Two of those sites are at ...

A Green Leap Forward Eco State Restructuring And The Tianjin Binhai Eco City Model, I-Chun Chang, Helga Leitner, Eric Sheppard 2016 Macalester College

A Green Leap Forward Eco State Restructuring And The Tianjin Binhai Eco City Model, I-Chun Chang, Helga Leitner, Eric Sheppard

I-Chun Catherine Chang

"A green leap forward? Eco-state restructuring and the Tianjin–Binhai eco-city model. Regional Studies. China has experienced a remarkable explosion of designated eco-cities since the year 2000, with Tianjin–Binhai becoming the best-practice model. Embedded in broader political economic changes, shifting multi-scalar regimes of environmental governance have shaped this efflorescence. Applying eco-state restructuring, this paper argues that eco-city construction became a new strategic project after the 2000s, driven by central state-driven model cities and assessment initiatives. This also led to a very different kind of ‘best practice’ eco-city model: Tianjin–Binhai, a China–Singapore collaboration in which greenness is manufactured ...

Coupling Community Preferences With Hydrologic Evaluation Of Low Impact Development Implementation In An Urban Watershed, Corinna M. Fleischmann, Carol Atkinson-Palombo, Joseph T. Bushey, Eric D. Jackson, David W. Payne

Suburban Sustainability

Stormwater runoff, and its associated pollutants, is a major problem in urban watersheds where the runoff is either channeled into surface water bodies or wastewater treatment plants. One emerging Best Management Practice (BMP) to control stormwater runoff is low impact development (LID). The EPA Stormwater Management Model (SWMM) was used to evaluate the hydrologic effectiveness at a watershed scale of five LID technologies (vegetated swales, bioretention cells, porous pavement, rain barrels and tree boxes) in an existing, typical urban watershed. As implementation focused on public transportation areas, hydrologic effectiveness of runoff reduction was assessed as a function of roadway length ...


Cruising The Canal: A Methodological Approach To Assessing Trail Conditions Along The Hennepin Canal Parkway, Alyssa Clarida 2016 Augustana College, Rock Island Illinois

Cruising The Canal: A Methodological Approach To Assessing Trail Conditions Along The Hennepin Canal Parkway, Alyssa Clarida

Geography: Student Scholarship & Creative Works

Trail conditions in the United States are degrading and trail systems do not receive enough funding to repair them in a timely manner. Park managers often conduct trail assessments to collect trail condition data. They use this data to make timely and judicious decisions regarding trail repairs. However, many trail assessments are time consuming, costly, and require high levels of expertise. This project creates a trail assessment methodology that can be applied to a trail with limited funds. The final methodology was efficient, succinct, accurate, and simple to conduct. It uses a problem based methodology where every instance of degradation ...

Undergraduate Honors Theses

This thesis looks at water management strategies for conservation of residential water use in the midst of drought, and the effectiveness of these strategies. There is a lot to be learned from past mistakes and successes in the way that water managers and states approach the problem of drought. Water is a vital resource that needs to be properly handled, and the current drought in California is leaving many districts struggling to find ways to conserve water. In this document three districts are looked at, two in California (Western Municipal Water District in southern California and East Bay Municipal Water ...


Wildfire, Climate And Species Distribution: Possible Futures Of The Rocky Mountain White Fir (A. Concolor Var. Concolor) In Colorado And New Mexico, Mollie K. Buckland 2016 University of Colorado Boulder Department of Geography

Wildfire, Climate And Species Distribution: Possible Futures Of The Rocky Mountain White Fir (A. Concolor Var. Concolor) In Colorado And New Mexico, Mollie K. Buckland

Undergraduate Honors Theses

Humans have altered their natural surroundings since their appearance on Earth. More recently, humans have increased their impact on natural systems causing changes in wildfire behavior, climate and species distribution to occur at a higher rate post Industrial Revolution. Unfortunately, research into wildfire, climate and species distribution tends to be narrowly focused. When investigating the effects that wildfire, climate and species distribution have on each other, it becomes clear that each variable affects the other, but the outcomes of those interactions remain unknown. In order to begin to understand these interactions, this study focuses on a single, tree species, the ...


A Review Of Historic And Modern Oil And Natural Gas Well Drilling And Abandonment In Greeley, Colorado, And The Potential Applications Of A Historic Geographic Information System, Will Benjamin Ulysses Rempel 2016 University of Colorado, Boulder

A Review Of Historic And Modern Oil And Natural Gas Well Drilling And Abandonment In Greeley, Colorado, And The Potential Applications Of A Historic Geographic Information System, Will Benjamin Ulysses Rempel

Undergraduate Honors Theses

In Colorado, a majority of existing and planned oil and natural gas operations occur along the populous Front Range of the Rocky Mountains, with a particular focus in Weld County. In recent years, unconventional oil and gas operations have lead to a surge of new activity in the region that has affected both rural and suburban areas, bringing environmental impact and social pros and cons. This has been a source of contention for numerous communities, and has brought legal disputes between local and state officials concerning drilling permission jurisdiction. Simultaneously, the region’s historic link to oil and gas wells ...
