Comparison of a Riverine Waterborne Transport and Dispersion Model and Yellowstone River Dye Releases
Abstract
As part of a multi-phase study, we have continued evaluating the predictive capabilities and performance of the waterborne transport and dispersion model known as the Incident Command Tool for Protecting Drinking Water (ICWater). The overarching goal of the study is to provide DTRA with information on the predictive reliability of this software package. In this second-year report, we compare ICWater simulation results to field measurements collected by the USGS during a series of dye experiments conducted in the Yellowstone River. The key conclusions arising from the study are that the velocity-flow expression used in ICWater causes the model to predict late plume arrival times and over predict peak concentration levels. It is suggested that the velocity-flow equation be improved or that real-time velocity be used instead of a velocity inferred from flow. Recommendations for future work are also discussed.
