The role of policy and collaboration in decommissioning exempt water wells in Washington state

Creator:: Moran, Kathryn A.
Abstract:: The rapid proliferation of exempt wells since the settlement of the West has left the State of Washington with little knowledge of the existing number of exempt wells within its boundaries. Exempt wells are primarily a rural phenomena that when abandoned leave aquifers vulnerable to contaminants and create a general...

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...

The Effects of Biofilm on Sandy Soil Hydrology

Creator:: Runion, Danielle N.
Abstract:: It is known that soil biota affects water dynamics through various complex mechanisms. The impact on retention by soil biota are due to a combination of changes to pore geometry, pore clogging by biofilms, biofilms that serve to connect thin water films across many pores as the soil dries, and...

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...

Hydrogeology and Hydrologic Connectivity of a Semiarid Central Oregon Rangeland System

Creator:: Caruso, Philip
Abstract:: The hydrologic function of a landscape is an important concept for understanding the presence, movement and availability of water. The Camp Creek Paired Watershed Study (CCPWS) site in Central Oregon has been utilized to investigate the impacts of western juniper on watershed hydrologic function since 1993. The research presented here...

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;...

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...

Assessment of Decentralized Wastewater Treatment System- Potential Impact on Water Quality

Creator:: Chavan, Padmaja Ramesh
Abstract:: Watershed analysis is a method used to collectively characterize ecosystem elements present within a watershed. Wastewater flow and pollutant content help to define the appropriate wastewater treatment system necessary to treat the wastewater within the watershed. Watershed monitoring aids to investigate the potential contamination through analysis of surface waterbodies. Major...

Investigating Management of Transboundary Basins between Sovereign Countries and Non-Sovereign Entities

Creator:: Altingoz, Mehmet S.
Abstract:: There is a significant gap in academia in the field of transboundary water management of the non-sovereign entities. The objective of this master’s thesis is to work towards filling this gap. The first part of this master’s thesis research identifies potential hydro political tension risks of the transboundary basins in...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
