An Assessment Of The Impacts Of Climate Change On The Upper Clackamas River Basin With A Distributed Hydrologic Model, David Graves Aug 2005

An Assessment Of The Impacts Of Climate Change On The Upper Clackamas River Basin With A Distributed Hydrologic Model, David Graves

Dissertations and Theses

The Pacific Northwest is dependent on seasonal snowmelt for water resources that support a significant portion of its economy. Increased temperatures resulting from higher concentrations of atmospheric greenhouse gases may cause disruptions to these resources because of reductions in the annual snowpack and variations of the timing of snowmelt. This study reconstructs and applies a GIS-based distributed hydrologic model at a monthly scale to assess the effects of future climate change on runoff from the Upper Clackamas River Basin (located near Portland, Oregon). Historic flow data and snow measurements are used to calibrate and test the performance of the hydro …


Ambivalent Landscapes: An Historical Geography Of Recreation And Tourism On Mount Hood, Oregon, Ryan Franklin Mitchell Jun 2005

Ambivalent Landscapes: An Historical Geography Of Recreation And Tourism On Mount Hood, Oregon, Ryan Franklin Mitchell

Dissertations and Theses

Mount Hood is an Oregon icon. The mountain has as long and rich a history of recreation and tourism as almost any other place in the American West. But contemporary landscapes on Mount Hood reveal a recreation and tourism industry that has struggled to assert itself, and a distinct geographic divide is evident in the manner in which tourism has been developed. Why? In this study I chronicle the historical geography of recreation and tourism on Mount Hood. I examine the evolution of its character and pattern, and the ways in which various communities have used it to invest meaning …


Visualizing Complexity : A Spatial Analysis Of Decorative Geometric Pattern In The Islamic World, 900-1400 Ad, Tracy Elizabeth Harrison Jun 2005

Visualizing Complexity : A Spatial Analysis Of Decorative Geometric Pattern In The Islamic World, 900-1400 Ad, Tracy Elizabeth Harrison

Dissertations and Theses

This study explores how the use of complex decorative geometric patterns in Islamic architecture spatially relates to advances in the fields of science and philosophy in the Islamic world between the ninth and fourteenth centuries. This project examines hypotheses developed by vario~s scholars on the forces that shaped the use of these patterns (known as the geometric mode) in Islamic architecture. The prevailing assumption that advances in mathematics contributed to the use of the geometric mode is used as a starting point for subsequent analysis.

For this study, two spatial databases were created. One contains over two hundred and twenty …


Forest Resource Use, Land-Use, And Ecotourism In The RíO PláTano Biosphere Reserve, Honduras, Christina Marie Friedle May 2005

Forest Resource Use, Land-Use, And Ecotourism In The RíO PláTano Biosphere Reserve, Honduras, Christina Marie Friedle

Dissertations and Theses

The Río Pláttano Biosphere Reserve, a tropical rainforest reserve in the northeastern corner of Honduras, is home to several subsistence-based indigenous groups, including the Miskito, Pech and Garifuna, as well as the non-indigenous Ladinos. Communities within the reserve depend on forest resources, swidden agriculture, marine resources and/or small-scale ranching as the foundations for local economies. Regulations placed on these subsistence practices, after establishment of the biosphere reserve in 1980, have created unique and new pressures and resulted in a blend of traditional and innovative resource use. A notable result is the promotion of ecotourism as a solution for meeting the …


"Alberta Arts District" : Boundaries And Belonging Among Long-Time Residents In A Culturally Changing Neighborhood, Sammy Shaw Jan 2005

"Alberta Arts District" : Boundaries And Belonging Among Long-Time Residents In A Culturally Changing Neighborhood, Sammy Shaw

Dissertations and Theses

This study takes a cultural perspective in studying the "Alberta Arts District," a gentrifying neighborhood in Northeast Portland in which bohemian cultural production/consumption has become the dominant and commodified vision of the community. Survey data demonstrates residents' general opinions and levels of participation in the changing neighborhood. Forty long-time residents, black and white, homeowners and renters, are interviewed in-depth regarding their perceptions of change. Long-time residents of gentrifying neighborhoods are often overlooked as a less powerful group that only has to negotiate rising rents and property values. This study approaches the meaning of neighborhood changes for long-time residents who have …


Fuel Model Development And Fire Simulation Analysis In The Wildland-Urban Interface : The Case Of Forest Park, Portland, Oregon, David Malcolm Kuhn Jan 2005

Fuel Model Development And Fire Simulation Analysis In The Wildland-Urban Interface : The Case Of Forest Park, Portland, Oregon, David Malcolm Kuhn

Dissertations and Theses

Forest Park, a 5,000 acre heavily-forested park within the city limits of Portland, Oregon was selected as the study area for performing a fire simulation analysis. A well-documented fire swept over a large area of the park in 1951, and provides both direct inputs, including the ignition point, and context for the present day fire simulations. The goal of the research was two fold. First, determine the difference between small area simulations using standard and custom surface fuel models. Second, determine if fire simulation can be an effective tool in assessing fire danger and behavior in a wildland-urban interface environment …
