Ecohydrologic Connections in Semiarid Rangeland Ecosystems in Oregon

Creator:: Durfee, Nicole M.
Abstract:: An improved understanding of the ecohydrologic relationships in semiarid rangelands is imperative for the development of effective rehabilitation and land management practices. This thesis addresses the ecohydrologic relationships of two significant issues concerning semiarid rangeland ecosystems: western juniper encroachment and increasing stream temperatures. This thesis is divided into two chapters;...

A Hydrogeologic Framework for Understanding Watershed-Scale Surface Water and Groundwater Interactions in Western Oregon, USA

Creator:: Hall, Jesse L.
Abstract:: Stream water quality, including stream temperature, has become an increasingly important issue in recent years. Warming streams can harm aquatic ecosystems by pushing fish from traditional breading grounds, forcing them to migrate, adapt, or perish. Recent research from Scripps Institute of Oceanography at UC San Diego has shown that climate...

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

Quantifying the Geomorphic Response of Stage 0 Stream Restoration: A Pilot Project on Whychus Creek

Creator:: Scagliotti, Alex
Abstract:: It is generally accepted in stream ecology that habitat heterogeneity and patchiness at multiple scales increases ecosystem resilience through niche diversification. Heterogeneous stream habitats include a complex mosaic of hydraulic features, large woody debris, anabranches, substrata and channel forms - this complexity tends to increase as streams progress towards later...
Resource Type:: Capstone Project

Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

Creator:: Burch, Sarah
Abstract:: Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...

Entrepreneur Well-Being and Organizational Decision Making Biases

Creator:: Kozlak, Scott
Abstract:: This dissertation consists of three essays that provide comprehensive insights into the complex dynamics shaping entrepreneurial and organizational outcomes. In the first essay I incorporate the Biophilia Hypothesis and the Challenge Hindrance Stressor framework to study entrepreneurial creativity. The findings emphasize the importance of more frequent nature visits for entrepreneurs...

Flow From Flexibility : Identifying Opportunities For Streamflow Restoration in a Transboundary Municipal Watershed Through Water Budgeting

Creator:: Pierson, Jessica S.
Abstract:: Municipal watersheds attempt to balance growing and conflicting demands for water for human use and for ecosystems. The Mill Creek basin, a 295 km2 basin in southeast Washington, exemplifies these conflicts. Since the late 1800s, the City of Walla Walla has withdrawn water from Mill Creek for municipal use. However,...

Exploring Vulnerability and Scarcity of Groundwater Resources in Quintana Roo, Mexico

Creator:: Iglesias Thome, Maria Jose
Abstract:: This study examined water scarcity and vulnerability in Quintana Roo, along the northern Caribbean coast of Mexico where rapid growth of tourism in the past 40 years has limited the ability of rural and urban communities to obtain safe, reliable, and equitable access to water services and critical water infrastructure...

What are the Roles of International Water Organizations in Climate Change Adaptation?

Creator:: Adkhamov, Utkir
Abstract:: Water and climate change are interconnected with each other. Water is a medium through which the climate change manifests its far-reaching consequences on society. Sustainable water management practices are fundamental in implementing effective climate change adaptation. Given an influential position as global water actors, international water organizations (IWOs) play a...

Africa-Appropriate Urban Stormwater Management: The State of the Art

Creator:: Kahsai, Simon K.
Abstract:: Urban development causes changes in the hydrology, increasing stormwater runoff volumes, which often leads to flooding and ecosystem degradation. This is a common phenomenon in most urban Africa, due to lack of stormwater drainage infrastructures. Green Infrastructure (GI) has been shown to be an effective approach to lessen the effects...
