The Walla Walla Subbasin (WWSB) in Oregon is underlain by formations of the extensive Columbia River Basalt Group (CRBG) which have been deformed by post-Miocene folding and faulting. Extensive irrigation with groundwater from these basalt groups, as well as sedimentary aquifers and surface water diversions from the Walla Walla River,...
The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

A recent surge in the development of irrigated agriculture in
the Fort Rock Basin of the Oregon High Desert has resulted in two
principal types of agricultural operations in the area: cow-calf
operators and cash-crop agriculturalists. The agroclimatic
hazards associated with the present situation and the implications
of those hazards...
Loss of anadromous and resident fish habitat has become
an increasing concern in the Columbia River Basin. Forest
management practices play a role in the health of headwater
stream habitat. The effects of instream large woody debris
is known to effect stream morphology and fish habitat. This
paper considers effects...
Use of backcountry areas in winter by crosscountry skiers, snowshoers, climbers, snowmobilers and others has increased rapidly in the Mt. Hood area of Oregon in recent years. With this increase in use a larger segment of the user population is being exposed to potential a.,pl.H11 Winger. purpose of this study...
There is a wide variety of developed, undeveloped
and proposed outdoor recreation areas and facilities in
Benton County. Recreation areas and facilities are supplied
by federal, state, county, city and private agencies.
Each agency plans for recreation development independently.
The Benton County Parks Department and the city of Corvallis
use...
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...
The concept of ecosystem services broadens perspectives on nature to include not only intrinsic value but also the utilitarian value it provides to society. Viewing nature through this lens informs our understanding of how particular ecological processes benefit different actors. In this research, I examine how water utilities in the...
The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...
In the Colombian Amazon there has been a complex interplay of rebel groups’ control over land, drug trafficking, and absence of the Government of Colombia. Here, I use satellite remote sensing, ethnographic research and statistical models to provide insights into causal effect and causal mechanisms of land change and economic...
