  1. A finite difference soil-structure interaction study of a section of the Bonneville Navigation Lock buttress diaphragm wall...

    The P-y curve, used in current practice as an efficient Iine-load vs. soi displacement model for input into the finite difference method of laterally loaded pile analysis, is extended in this study for use with...

  2. The Aeolian Flux of Calcium, Chloride and Nitrate to the McMurdo Dry Valleys Landscape: Evidence from Snow Pit Analysis

    We have determined the flux of calcium, chloride and nitrate to the McMurdo Dry Valleys region by analysing snow pits for their chemical composition and their snow accumulation using multiple records spanning...

  3. A Geospatial Tool for Wetland Prioritization at the Watershed Scale

    There is an increasing demand for assessing ecosystem functions for freshwater wetlands, especially when comparing or prioritizing among wetlands at the watershed scale. We estimated the relative potential of...

  4. Assessing Soil Lead Contamination at Multiple Scales in Oakland, California: Implications for Urban Agriculture and...

    As urban agriculture grows in popularity throughout North America, vacant lots, underutilized parks, and other open spaces are becoming prime targets for food production. In many post-industrial landscapes and...

  5. Piloting a Program-level Learning Assessment Plan in Plant and Soil Science

    Faculty of Washington State University's undergraduate degree programs in Crop Science, Soil Science, and Horticulture initiated the development and implementation of an assessment process to gauge the extent...

  6. Long-term Ecological Research in Forest Park: Tracking Urban Impacts to Forest Structure and Productivity

    Current and historic land use practices as well as exposure to an urban environment can impact forest structure and function. Past and ongoing research in Forest Park, a large urban forest in Portland, Oregon,...

  7. Minimization of the First-Year Cost of an Active Soil Ventilation System Using Integer Programming Techniques

    In this project we determined the minimum first-year cost of an active soil ventilation system. The results indicate the duct diameter and the fan brand that achieve the minimum cost. Some aspects of the...

  8. Dendrochronology and Middle Miocene Petrified Oak: Modern Counterparts and Interpretation

    This study reports the first successful statistical crossdating among many ring width time series from petrified wood, thus providing a replicable continuous annual resolution window into tree growth and...

  9. 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...

  10. Effects of Arbuscular Mycorrhizal Fungal Infection and Common Mycelial Network Formation on Invasive Plant Competition

    Understanding the biotic factors influencing invasive plant performance is essential for managing invaded land and preventing further exotic establishment and spread. I studied how competition between both...
