  1. Map-based Probabilistic Infinite Slope Analysis of the Stephens Creek Watershed, Portland, Oregon

    The Stephens Creek Watershed in southwest Portland, Oregon was chosen by the city as a pilot project for urban stream restoration efforts, and the infiltration of stormwater was identified as a potential...

  2. 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...

  3. 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...

  4. Scenario Development and Analysis of Freshwater Ecosystem Services under Land Cover and Climate Change in the Tualatin and...

    Humans make decisions within ecosystems to enhance their well-being, but choices can lead to unintended consequences. The ecosystem services (ES) approach supports decision-making that considers all...

  5. Effects of HRU Size on PRMS Performance in 30 Western U.S. Basins

    Semi-distributed hydrological models are often used for streamflow forecasting, hydrological climate change impact assessments, and other applications. In such models, basins are broken up into hydrologic...

  6. Investigating the Link Between Surface Water and Groundwater in the Tule Lake Subbasin, Oregon and California

    Water allocation in the upper Klamath Basin of Oregon and California has been challenging. Irrigators have increasingly turned to groundwater to make up for surface water shortages because of shifts in...

  7. Factors of Successful Collaboration: Oregon's Watershed Councils as Collaborative Systems

    The public sector, business professionals and organization leaders are among some of the diverse entities increasingly viewing collaboration as a useful, and at times necessary, practice. Collaborative systems...

  8. Modeling Fecal Bacteria in Oregon Coastal Streams Using Spatially Explicit Watershed Characteristics

    Pathogens, such as Escherichia coli and fecal coliforms, are causing the majority of water quality impairments in U.S., making up ~87% of this grouping's violations. Predicting and characterizing source,...

  9. A Review of Urban Water Body Challenges and Approaches: (1) Rehabilitation and Remediation

    We review how urbanization alters aquatic ecosystems, as well as actions that managers can take to remediate urban waters. Urbanization affects streams by fundamentally altering longitudinal and lateral...

  10. Riparian Vegetation Assemblages and Associated Landscape Factors Across an Urbanizing Metropolitan Area

    While diverse, native riparian vegetation provides important functions, it remains unclear to what extent these assemblages can persist in urban areas, and under what conditions. We characterized forested...
