Water Whiplash In Mediterranean Regions Of The World, Citlalli Madrigal, Rama Bedri, Thomas Piechota, Wenzhao Li, Glenn Tootle, Hesham El-Askary
Water Whiplash In Mediterranean Regions Of The World, Citlalli Madrigal, Rama Bedri, Thomas Piechota, Wenzhao Li, Glenn Tootle, Hesham El-Askary
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The presence of weather and water whiplash in Mediterranean regions of the world is analyzed using historical streamflow records from 1926 to 2023, depending on the region. Streamflow from the United States (California), Italy, Australia, Chile, and South Africa is analyzed using publicly available databases. Water whiplash—or the rapid shift of wet and dry periods—are compared. Wet and dry periods are defined based on annual deviations from the historical record average, and whiplash occurs when there is an abrupt change that overcomes an accommodated deficit or surplus. Of all the stations, there are more dry years (56%) than wet years …
Atlantic Ocean Variability And European Alps Winter Precipitation, Giuseppe Formetta, Jonghun Kam, Sahar Sadeghi, Glenn Tootle, Thomas Piechota
Atlantic Ocean Variability And European Alps Winter Precipitation, Giuseppe Formetta, Jonghun Kam, Sahar Sadeghi, Glenn Tootle, Thomas Piechota
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Winter precipitation (snowpack) in the European Alps provides a critical source of freshwater to major river basins such as the Danube, Rhine, and Po. Previous research identified Atlantic Ocean variability and hydrologic responses in the European Alps. The research presented here evaluates Atlantic Sea Surface Temperatures (SSTs) and European Alps winter precipitation variability using Singular Value Decomposition. Regions in the north and mid-Atlantic from the SSTs were identified as being tele-connected with winter precipitation in the European Alps. Indices were generated for these Atlantic SST regions to use in prediction of precipitation. Regression and non-parametric models were developed using the …
California Drought Outlooks Based On Climate Change Models’ Effects On Water Availability, Lauren Lynam, Thomas Piechota
California Drought Outlooks Based On Climate Change Models’ Effects On Water Availability, Lauren Lynam, Thomas Piechota
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Future streamflow in California is evaluated based on eight climate projections models and the effects on water availability. The unimpaired projected streamflow for eleven California rivers, collected from Cal-Adapt, are compared with unimpaired historical flows (1950–2015) using eight climate model projections (2020–2099) identified as representative as possible future scenarios; Warm Dry RCP 4.5, Average RCP 4.5, Cool Wet RCP 4.5, Other RCP 4.5, Warm Dry RCP 8.5, Average RCP 8.5, Cool Wet RCP 8.5, and Other RCP 8.5. Projected drought deficits (or magnitudes), durations, and intensities are statistically tested against historical values to determine significance of differences between past streamflow …
Using A Design Charrette And State Of The Art Coastal Modeling To Support Local Government Adaptation To Sea Level Rise, Carol Macilroy, John Doyle, Eric Grossman, Guillaume Mauger
Using A Design Charrette And State Of The Art Coastal Modeling To Support Local Government Adaptation To Sea Level Rise, Carol Macilroy, John Doyle, Eric Grossman, Guillaume Mauger
Salish Sea Ecosystem Conference
The majority of the Town of La Conner sits at an elevation (MLLW) of 8-13 feet where over the last number of years Town staff have gone from seeing the baseboards of their overwater business district being reached once or twice every four to five years to being reached four to five times a year. These high water events come at great expense to the Town and leave the Town regularly just shy of a major disaster. The Town of La Conner partnered with the Skagit Climate Science Consortium (including USGS, UW Climate Impacts Group and Western Washington University) and …
Kelp Forest Dynamics: Links To Climate And Long Term Trends, Helen Berry, Cathy Pfister, Tom Mumford
Kelp Forest Dynamics: Links To Climate And Long Term Trends, Helen Berry, Cathy Pfister, Tom Mumford
Salish Sea Ecosystem Conference
Kelp forests are foundation species in the Salish Sea, and their dynamics are key to the fate of many other species. Research in other regions has shown that kelp abundance is driven in part by climate and can be impacted by human activities (for example, pollution and altered competition among species). While downward trends in kelp abundance have been of concern globally, trends are often locally distinct. We combined long term monitoring datasets and historical records to explore whether bull kelp (Nereocystis luetkeana) and giant kelp (Macrocystis pyrifera) dynamics in the Salish Sea region: 1) correlate with climate conditions, and …
A Watershed Approach To Recovering Salmon In Changing Climate Conditions, Beth Ledoux, Jessica Engel, Morgan Schniedler Ruff, Colin Wahl
A Watershed Approach To Recovering Salmon In Changing Climate Conditions, Beth Ledoux, Jessica Engel, Morgan Schniedler Ruff, Colin Wahl
Salish Sea Ecosystem Conference
The Snohomish Basin Forum adopted the Snohomish Basin Protection Plan in 2015 which clearly stated that the survival of our iconic salmon will be challenged by climate change. From that integrative watershed planning effort the Snohomish Basin Technical Committee investigated how locally predicted impacts of climate change affect salmon recovery in the Snohomish Basin and what key actions can be taken to ameliorate those impacts. As the basin continues to implement the Snohomish Basin Salmon Recovery Plan, it will be critical to restore and protect areas that preserve the basin’s hydrologic patterns and key habitat functions that support salmon in …
Integrated Floodplain Management In Washington: How Can We Make It More Resilient?, Guillaume Mauger, Andrew M. Smith, Cindy Dittbrenner, Se-Yeun Lee, Jason Won
Integrated Floodplain Management In Washington: How Can We Make It More Resilient?, Guillaume Mauger, Andrew M. Smith, Cindy Dittbrenner, Se-Yeun Lee, Jason Won
Salish Sea Ecosystem Conference
Floodplains are home to a wide range of economic, cultural, and natural resources. Although there is a strong desire to include climate change into these planning efforts, very little guidance has been developed to help incorporate climate impacts into planning and design. This is further complicated by weak or non-existent coordination among the various agencies, jurisdictions, and interests that have a stake in floodplain management. This talk will describe a recent assessment – from the perspective of agency-level flood risk managers – of ways to better integrate climate change in floodplain management. The work was focused on the Washington State …
Climate Robust Culvert Design: Probabilistic Estimates Of Fish Passage Impediments, Guillaume Mauger, Alan F. Hamlet, Se-Yeun Lee, Jason Won
Climate Robust Culvert Design: Probabilistic Estimates Of Fish Passage Impediments, Guillaume Mauger, Alan F. Hamlet, Se-Yeun Lee, Jason Won
Salish Sea Ecosystem Conference
*** This abstract is for a "Snapshot" (5-min) presentation. *** Many Washington State culverts are currently inadequate for fish passage. Apart from a few special cases, the standard for sizing culverts in Washington State is based on a simple linear function of bankfull width (BFW). This reflects a geomorphic approach to culvert design that can be applied across a large range of situations (Barnard et al. 2013, 2015). Future changes in BFW have previously been estimated by the Washington Department of Fish and Wildlife (WDFW) (Wilhere et al. 2016), by estimating the percent change in BFW derived from projected changes …
Geochemical And Stratigraphic Analysis Of The Linnévatnet Sediment Record: A Study Of Late Holocene Cirque Glacier Activity In Spitsbergen, Svalbard, Graham Harper Edwards
Geochemical And Stratigraphic Analysis Of The Linnévatnet Sediment Record: A Study Of Late Holocene Cirque Glacier Activity In Spitsbergen, Svalbard, Graham Harper Edwards
Honors Projects
Morainal and lacustrine sediments in Linnédalen, Spitsbergen, Svalbard, record the fluctuations of a glacier in a currently unglaciated mountain cirque during the Little Ice Age (LIA). This study attempts to reconstruct Late Holocene glacial activity within this cirque from geochemical, physical, and visual stratigraphic variation of the Linnévatnet lacustrine sediment record. A 57 cm lacustrine sediment core (D10.5) from Linnévatnet was analyzed at a high-resolution for variations in X-Ray Fluorescence (XRF)-measured elemental composition, spectral reflectance, and magnetic susceptibility. The visual stratigraphy was observed at a microscopic scale. An age-depth model for D10.5 is developed by extrapolating sedimentation rates from dated …

Measurements Of Salinity In The Coastal Ocean: A Review Of Requirements And Technologies, Catherine Woody, Eddie Shih, Jerry Miller, Thomas Royer, Larry P. Atkinson, Richard S. Moody
CCPO Publications
Salinity, a measure of the dissolved salts in seawater, is a fundamental property of seawater and basic to understanding biological and physical processes in coastal waters. In the open ocean long term salinity measurements are identified as necessary to understand global climate studies, hydrological cycle, and circulation. In the coastal oceans, information on salinity is critical to understanding biological effects on ecosystem function such as disease, nursery grounds, or harmful algal blooms and on physical processes such as freshwater runoff estuarine mixing, and coastal currents. While the importance of salinity is recognized, little attention has been given to making routine …
Long-Term Reconstruction And Analysis Of White River Streamflow, M. K. Cleaveland, D. W. Stahle, J. G. Hehr
Long-Term Reconstruction And Analysis Of White River Streamflow, M. K. Cleaveland, D. W. Stahle, J. G. Hehr
Technical Reports
A 281-year reconstruction of White River annual runoff at Clarendon, Arkansas, was developed from a regional average of nine Oklahoma, Missouri, and Arkansas tree-ring chronologies (six post oak, Quercus stellata, and three baldcypress, Taxodium distichum). Inhomogeneity of the gaged series was detected with both double mass analysis (using state average total annual Arkansas precipitation) and regression (using the regional tree-ring average). Simple regression calibrated the homogeneous runoff data with the average ring width data from 1930 to 1980. Comparing the reconstruction with independent data verified the regression model. Variance of the reconstruction increases significantly during the 20th century, a change …
A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon
A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon
Resource management technical reports
Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.
