  • The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

    Creator:
    Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
    Abstract:
    Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

    Dalton, Meghan, Fleishman, Erica, Bachelet, Dominique, and Rupp, David
    Abstract:
    In this report, we present future climate projections for Polk County relevant to specified natural hazards for the 2020s (2010–2039) and 2050s (2040–2069) relative to the 1971–2000 historical baseline. We present projections that are based on multiple global climate models for both a lower greenhouse gas emissions scenario (RCP 4.5)...

  • Future climate projections. Jackson County : February 2023

    Creator:
    Dalton, Meghan, Fleishman, Erica, and Bachelet, Dominique
    Abstract:
    Climate change is expected to increase the occurrence of many climate-related natural hazards. Confidence that the risk of heat waves will increase is very high given strong evidence in the peer-reviewed literature, consistency among the projections of different global climate models, and robust scientific principles that explain why temperatures increase...

  • Vegetation composition and response to fire of native Willamette Valley wetland prairies

    Creator:
    Pendergrass, Kathy L. (Connelly)
    Abstract:
    Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...
