Protecting Society from Itself: Reconnecting Ecology and Economy
(University of Washington Water Center, 2007-02-14)
Karr will present the paradox: As scientific understanding of Earth and the effects of humans on Earth systems expand, the threats to Earth's living systems—human and nonhuman—worsen.
He will ask: How can we be smarter and more knowledgeable, yet ignore so many of the lessons of that knowledge? He will argue that humanity ...
Making Sense from Measurements -- Statistical Advances that Yield More, but Demand More
(University of Washington Water Center, 2004-02-06)
Conquest will review traditional sample designs. Next, she will discuss recent advances: ranked set sampling and multiple-panel sampling. She will describe "Visual Sample Plan" software, and then offer some conclusions.
Impacts and Land-Use Change on Hydrology of a Mountainous Watershed: Water Resource Tension in Northern Thailand
(University of Washington Water Center, 2004-02-06)
Rattanaviwatpong will describe a study about water resource conflicts in northern Thailand. She will provide an overview of the research, including the study site, the water resource problem, research objectives, implementation, results, conclusions, and management implications.
Stream Size Mediates the Ecological Effects of Bear Predation on Salmon
(University of Washington Water Center, 2006-02-16)
Quinn will describe a study of salmon predation by bears in Alaska. The study looked at the controls on the number and proportion of salmon killed in a creek each year. Quinn will outline the observed patterns: 1. Bears kill a higher proportion of the salmon in narrow than wide streams. 2.The number of salmon killed reaches ...
Dirt: The Erosion of Civilizations
(University of Washington Water Center, 2008-02-14)
Montgomery will review the importance of soil in sustaining civilizations. He will ask the question: can soil erosion limit the lifespan of civilizations? He will discuss contemporary
and long-term (geological)
erosion rates -- and
agricultural erosion rates in
particular.
Vertical Channel Change Associated with Wood Accumulations: Implications for Delineating Channel Migration Zones
(University of Washington Water Center, 2006-02-16)
Montgomery will discuss the role of coarse woody debris in river ecosystems. He concludes that one of the few salmon conservation strategies that might work over a long run would be to restore a network of forested river corridors along river floodplains.
Watershed Planning Experiments in Washington and Oregon
(University of Washington Water Center, 2006-02-16)
Ryan will describe a research study comparing watershed management strategies in Washington and Oregon. She will review each state's plan to obtain and sustain participation, as well as their balance of planning and projects. She will discuss the issues involved with building organizational capacity, and what we can learn ...
Aging Dams, Dam Removal, and Sustainable Development
(University of Washington Water Center, 2006-02-16)
Khagram will discuss adaptive management of existing dams for sustainable development. He will review environmental impacts and mitigation, social impacts, decision making and governance, water quality and human health and safety. Finally, he will talk about decommissioning dams, and policy and practice implications.
The Effect of LiDAR Digital Elevation Model Resolution on Stream Network Prediction and Computational Requirements
(University of Washington Water Center, 2006-02-16)
Mouton will describe his research into stream prediction. In his study, he examined the effects of digital elevation model (DEM) grid size for stream network predictions in the northwestern United States to test the accuracy of high-resolution LiDAR (Light Detection and Ranging) digital elevation data. He will describe the ...
Measuring What Matters, Counting What Counts to Sustain Salmon, Rivers, and People
(University of Washington Water Center, 2004-02-06)
Karr will discuss humanity's effects on salmon and rivers. He will identify the core problem: flawed indicators and models endorse values that promote unsustainable lifestyles. He will argue that we need improved indicators, so that we can create better assessments and more inclusive policy processes. He will present the case ...
