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 …


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 …
