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...

Hydrologic Modeling in Dynamic Catchments: A Data Assimilation Approach
The transferability of conceptual hydrologic models in time is often limited by both their structural deficiencies and adopted parameterizations. Adopting a stationary set of model parameters ignores biases...

Willamette River Basin Temperature TMDL Model: Model Calibration
The State of Oregon Department of Environmental Quality (DEQ) is developing a TMDL for temperature in the Willamette River basin shown in Figure 1. The study area included the Willamette River and all major...

Combined Assimilation of Streamflow and Satellite Soil Moisture with the Particle Filter and Geostatistical Modeling
Assimilation of satellite soil moisture and streamflow data into a distributed hydrologic model has received increasing attention over the past few years. This study provides a detailed analysis of the joint...

Maintaining Safe, Efficient and Sustainable Intermodal Transport Through the Port of Portland
About $15 billion of freight passes annually through the Lower Columbia River (LCR) navigation channel to reach Portland and Vancouver, where most of it connects with land transport. This commerce plays a vital...

River Influences on Shelf Ecosystems: Introduction and Synthesis
River Influences on Shelf Ecosystems (RISE) is the first comprehensive interdisciplinary study of the rates and dynamics governing the mixing of river and coastal waters in an eastern boundary current system,...

A sequential Bayesian approach for hydrologic model selection and prediction
When a single model is used for hydrologic prediction, it must be capable of estimating system behavior accurately at all times. Multiple-model approaches integrate several model behaviors and, when effective,...

Seasonal Variability and Estuary-Shelf Interactions in Circulation Dynamics of a River-dominated Estuary
The long-term response of circulation processes to external forcing has been quantified for the Columbia River estuary using in situ data from an existing coastal observatory. Circulation patterns were...
