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

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 …

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 …

Saginaw Chippewa Tribal Relations And The Social Production Of Space In Isabella County, Michigan, Bryan Thomas Swanson

Masters Theses

This thesis focuses on how the historical and cultural geography of the Saginaw Chippewa tribe of Mount Pleasant, Michigan and specifically on through their Soaring Eagle Casino reshaped the physical and cultural landscape of Isabella County. For this research I utilized documentary/archival evidence such as local histories, newspapers, plat maps and I also conducted field surveys. The research findings indicated that through the Soaring Eagle Casino the Saginaw Chippewa tribe has changed Isabella County, as well as their own social standing. Since 1993 the tribe has used casino revenues to purchase 1185 acres of land to add to the Isabella …

Methods For Correcting Topographically Induced Radiometric Distortion On Landsat Thematic Mapper Images For Land Cover Classification, David Michael Rosen

Geography Masters Research Papers

Satellite imagery is commonly used to study land-use, land-cover change in mountainous areas. Classification of land-cover types is particularly difficult in this type of terrain because topography affects the spectral response of surface features. Several techniques have been developed to help compensate for this topographic effect and to increase classification accuracy.

The purpose of this study is to compare topographic correction methods to determine which produces the most accurate results. Method 1 does not use any topographic correction, serving as a control. Method 2 is based on the Lambertian model, and uses topographical data as variables in an equation. Method …

The Major Vernacular Regions Of Tennessee, James Curtis Barker

Theses, Dissertations and Capstones

This research project delineates and examines the relative strength of the major vernacular culture regions of Tennessee. Vernacular regions are delineated by recording and mapping businesses and organizations whose identities contain a key element of a regional label, such as: East Tennessee auto sales, Delta awning, etc.. Data are collected using a popular internet telephone directory.

The number of listings occurring in each county is recorded for each regional label. The county totals for each region are used to generate population-weighted county index values (CIV). Maps of county index values (CIVs) display core and periphery tendencies within vernacular regions. The …
