  1. 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...

  2. 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...

  3. Modeling Liquid Solid Separation in a Coalescing Plate Oil Water Separator

    When precipitation occurs in undeveloped areas a number of abstractions catch and absorb the precipitation. Abstractions include plants and trees, which catch a portion of the water, pervious soils that...

  4. 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...

  5. Ensemble Prediction and Data Assimilation for Operational Hydrology

    This special section in the Journal of Hydrology will discuss the need for advancing hydrologic ensemble prediction and DA.

  6. Estimation of Historic Flows and Sediment Loads to San Francisco Bay, 1849 – 2011

    River flow and sediment transport in estuaries influence morphological development over decadal and century time scales, but hydrological and sedimentological records are typically too short to adequately...

  7. Northwest Forest Plan The First 20 Years (1994-2013): Watershed Condition Status and Trend

    We used two data sets to evaluate stream and upslope/riparian condition for sixth-field watersheds in each aquatic province within the Northwest Forest Plan (NWFP) area. The stream evaluation was based on...

  8. A Genetic Approach to Designing a Novel Biological Sensor to Monitor Water Contamination

    Many cities across the country have experienced extreme water problems. The City of Portland has issued several water boiling advisories due to E. coli contamination. Additionally, there has been incidents of...

  9. Effects of Ethnicity and Gender on Sixth-Grade Students' Environmental Knowledge and Attitudes After Participation in a...

    The goal of environmental education (EE) has always been to increase knowledge about the environment and to foster positive environmental attitudes. Increasingly, as the call for integrating EE programs into...

  10. Automatic Calibration of Water Quality and Hydrodynamic Model (CE-QUAL-W2)

    One of the most important purposes of surface water resource management is to develop predictive models to assist in identifying and evaluating operational and structural measures for improving water quality....
