Watershed and climate influences on flood frequency distributions in the Willamette River basin

Creator:: Tolle, Timothy Victor
Abstract:: Problem areas identified are: The needs a) to develop curve fitting procedures to estimate flood flow distributions; b) to incorporate precipitation data into frequency analysis procedures; and c) to better define flood potentials for ungauged streams. Closely related to the above, it is noted that variables commonly used to estimate...

Resilience of large river basins : applying social-ecological systems theory, conflict management, and collaboration on the Mekong and Columbia Basins

Creator:: MacQuarrie, Patrick R.
Abstract:: River basins provide essential services for both humans and ecosystems. Understanding the connections between ecosystems and society and their function has been at the heart of resilience studies and has become an increasing important endeavor in research and practice. In this dissertation, I define basin resilience as a river basin...

Enhancing social-ecological resilience in the Colorado River Basin

Creator:: Eidem, Nathan T.
Abstract:: This research presents the Colorado River basin as a social-ecological system. Utilizing event data on cooperative and conflictive interactions over fresh water, the system is decomposed to look for evidence of outcomes of resilience enhancement. The Animas-La Plata Project in the upper San Juan basin is presented as a case...

Water scarcity and reservoir reliability in basins affected by climate and land use change : impacts of hydrogeology, sensitivities, and uncertainties in the Santiam River Basin, Oregon

Creator:: Mateus, M. Cristina
Abstract:: Multipurpose management of hydrosystems face a number of uncertainties related to hydrologic variability and nonstationarity. Anticipated air temperature increases in the Pacific Northwest region are projected to alter the timing and quantity of streamflow associated with precipitation shifting from snow to rain, including shorter winter runoff periods, earlier spring runoff,...

Optimizing Reservoir Operations to Adapt to 21st Century Expectations of Climate and Social Change in the Willamette River Basin, Oregon

Creator:: Moore, Kathleen M.
Abstract:: Reservoir systems in the western US are managed to serve two main competing purposes: to reduce flooding during the winter and spring, and to provide water supply for multiple uses during the summer. Because the storage capacity of a reservoir cannot be used for both flood damage reduction and water...

Social Learning and Adaptive Capacity in Collaborative Watershed Partnerships

Creator:: Calvert, Daniel T.
Abstract:: This dissertation examines learning driven adaptations in salmon recovery efforts and water resources management in Oregon. The case study utilizes a framework highlighting the connections between human and natural systems. Semi-structured interviews are used to analyze interactions between rural riparian landowners and watershed council staffs living and working in Oregon’s...

Distribution and movements of Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin

Creator:: Eiler, John H.
Abstract:: Chinook salmon, Oncorhynchus tshawytscha, returning to the Yukon River basin and other large river systems in western Alaska have declined dramatically since the late 1990s. This continuing trend has raised concerns over the future status of the returns, and severely impacted commercial and subsistence fisheries within the drainage. Management is...

International river basin management in the face of change : Syr Darya Basin case study

Creator:: Pak, Mariya
Abstract:: The conflict over water resources exploitation and sharing in the Aral Sea Basin is one of the most pressing environmental issues yet to be resolved in Central Asia. The fall of the Soviet Union in 1991 and establishment of the New Independent States (NIS) within the Aral Sea Bain led...

Resilience and adaptability of transboundary rivers : the principle of equitable distribution of benefits and the institutional capacity of the Nile Basin

Creator:: Iyob, Biniam
Abstract:: Biophysical, socioeconomic and geopolitical pressures from population growth and economic development are leading to an increase in tensions regarding the sharing of water within transboundary basins. Transboundary basins are surface rivers and groundwater resources that are shared among sovereign nations and autonomous regions. This dissertation focuses on surface water in...
