  1. Engineering a Healthier Watershed: Middle School Students Use Engineering Design to Lessen the Impact of Their Campus'...

    It is important that students understand not only how their local watershed functions, but also how it is being impacted by impervious surfaces. Additionally, students need experience exploring the scientific...

  2. Assessing Hydrologic and Water Quality Sensitivities to Precipitation Changes, Urban Growth and Land Management Using SWAT

    Precipitation changes and urban growth are two factors altering the state of water quality. Changes in precipitation will alter the amount and timing of flows, and the corresponding sediment and nutrient...

  3. Focus on a STEM, Based in Place, Watershed Curriculum: A confluence of stormwater, humans, knowledge, attitudes, and skills

    This case study investigated the potential of a place-based watershed curriculum, using STEM principles, to increase watershed literacy and knowledge of human impacts on stormwater in the environment. A...

  4. Evaluating Global Sensitivity Analysis Methods for Hydrologic Modeling over the Columbia River Basin

    Global Sensitivity Analysis (GSA) approach helps to identify the effectiveness of model parameters or inputs and thus provides essential information about the model performance. The effects of 14 parameters and...

  5. Cascades Island Lamprey Passage Structure: Evaluating Passage and Migration Following Structure Modifications

    Pacific lamprey (Entosphenus tridentatus), an endemic species to the Columbia River Basin, U.S.A, has experienced staggering decreases in returns to spawning territories in recent decades. As lamprey are...

  6. Quantifying the Impacts of Initial Condition and Model Uncertainty on Hydrological Forecasts

    Forecasts of hydrological information are vital for many of society's functions. Availability of water is a requirement for any civilization, and this necessitates quantitative estimates of water for effective...

  7. Agricultural Management Decisions Impact Isoprene Emission and Physiology of Arundo donax, an Emerging Bioenergy Crop

    Arundo donax (Giant Reed) is quickly being developed as a rapidly-growing, robust, and highly productive bioenergy crop, with large scale cultivation of this species planned for the Columbia River basin of the...

  8. Interactions Among Fuel Management, Species Composition, Bark Beetles, and Climate Change and the Potential Effects on...

    Climate-driven increases in wildfires, drought conditions, and insect outbreaks are critical threats to forest carbon stores. In particular, bark beetles are important disturbance agents although their...

  9. Drainage Reversals Due to Tectonic Uplift: an Investigation through Modeling

    In mountainous landscapes throughout the world bedrock dominated river channels record a history of the tectonic and climatic evolution of the drainage basins that contain them. In traditional analysis of river...

  10. Chinookan Villages of the Lower Columbia

    Villages were the center of Chinookan life, filling the role that tribes did for Native people in other parts of North America. Every village of any size or significance had a recognized leader or chief, and...
