  1. Watershed Response to Climate Change and Fire-Burns in the Upper Umatilla River Basin Using the Precipitation Runoff Modeling...

    This study provides an analysis of watershed response to climate change and forest fire impacts, to better understand the hydrologic budget and inform water management decisions for present and future needs....

  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. 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...

  4. Landforms along the Lower Columbia River and the Influence of Humans

    River systems, such as the Columbia River in the Pacific Northwest, USA have been influenced by human activities, resulting in changes to the physical processes that drive landform evolution. This work...

  5. Climate Change Assessment in Columbia River Basin (CRB) Using Copula Based on Coupling of Temperature and Precipitation

    The multi downscaled-scenario products allow us to better assess the uncertainty of the variations of precipitation and temperature in the current and future periods. Joint Probability distribution functions...

  6. 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...

  7. City of Gresham Stormwater Retrofit Master Plan

    The Stormwater Retrofit Master Plan identifies more than 50 stormwater retrofit project opportunities across three watersheds in the City of Gresham. The retrofit projects are prioritized in a scoring system to...

  8. 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.

  9. 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...

  10. Effects of Spatially Distributed Stream Power on Check Dam Function in Small Upland Watersheds: A Case Study of the Upper...

    Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through...
