Developing a Consensus on the Impacts of Climate Change on Water Resources: a Puget Sound, Tri-County Perspective
(University of Washington Water Center, 2007-02-14)
Palmer will lay out the goals of this talk: 1. Provide accurate estimates of regional water supply and demand for planning. 2. Establish the need to include climate change in regional water supply planning. 3. Shift a planning paradigm through consensus. He will discuss evaluating the regional water supply, and provide an ...
Using Turbidity to Determine Total Suspended Solids in Urbanizing Streams in the Puget Lowlands
(Canadian Water Resources Association, 1999-10-01)
The replacement of forestland with impervious surfaces during urbanization can have significant effects on watershed hydrology and the quality of stormwater runoff. One component of water quality, total suspended solids (TSS), is both a significant part of physical and aesthetic degradation and a good indicator of other ...
Sediment Budget of a Mixed-Use, Urbanizing Watershed
(The Water Center, 2001-01-01)
The Issaquah Creek basin is an urbanizing watershed of 144 square km in western Washington, where sediment aggradation of the main channel and delivery of fine sediment into a large downstream lake have raised serious local and regional concerns. The basin has many water quality problems that may be associated with erosion ...
What Does a Stream Ecologist Need to Know About Fatty Acids?
(University of Washington Water Center, 2008-02-26)
Brett will outline controls on zooplankton fatty acid content: 1) Taxonomic affiliation. 2) Diet. 3) Temperature. 4) Food ration/starvation. 5) Biochemical transformations. 6) Homeostasis.
Marine Ecosystem Management in the San Juan Archipelago
(University of Washington Water Center, 2007-10-09)
Klinger will present an overview of marine ecosystem management in the San Juan Islands. The general approach: engage in a local, bottom-up planning process for ecosystem-based management, using science to support decision-making. She will review existing protection measures and recent county actions. She will describe ...
Planning and Management of Forested Agricultural Riparian Buffers: the Case of the Skagit County Managed Agricultural Riparian Plantations (MARP)
(University of Washington Water Center, 2006-10-03)
Riparian forests are part of a complex and interconnected ecosystem that extends from the headwaters to the estuaries. This presentation describes elements of silvicultural systems for riparian buffers on agricultural lands in large floodplains of Northwestern Washington State. Riparian buffers protect and enhance aquatic ...
Buffer Strips and Tree Windthrow: Proglem or Habitat Enhancement?
(University of Washington Water Center, 2007-11-27)
Martin will discuss windthrow in buffer strips. He will compare the effects of logging to the effects of storm exposed landscapes. Next, he will ask: What are the effects of tree windthrow in buffer strips on fish habitat? What is the magnitude and duration of habitat change? Martin will present research that illustrates these ...
Carbon and Water Exchange in Amazonian Rainforests
(University of Washington Water Center, 2008-02-19)
Hutyra will present the scientific background and characteristics of the Amazon rain forest. She will consider controls on the net ecosystem exchange of CO2, photosynthesis, and respiration. She will ask, is forest growth currently water limited? And how does logging impact the carbon exchange processes?
Wetland Restoration: Practical Approaches for Dealing with Thorny Problems
(University of Washington Water Center, 2007-11-20)
Ewing will discuss the primary causes of loss of coastal and freshwater wetlands. He will outline invasive species of concern and present restoration approaches. He will also discuss the challenges facing these efforts. Finally, he will present a theoretical framework for restoration, which considers ecosystem functions and services.
The Blue Death: the Past, Present and Future of Drinking Water and Health
(University of Washington Water Center, 2008-04-01)
Morris will present a history of waterborne diseases, beginning with the outbreak investigation of the cholera pandemic in England in the 1850s. He moves on to discuss problems in mdern public water supplies, including water treatment using chlorine.
