Abstract
In an early review of numerical reservoir hydrodynamic models, the US Army Corps of Engineers developed a physical model at the US Army Waterways Experiment Station to assess the performance of modeling cold water underflow with numerous 2-dimensional and 3-dimensional numerical hydrodynamic models. Within this effort, the precursor for CE-QUAL-W2, the Laterally Averaged Reservoir Model, was defined and applied with limited success in representing the vertical velocity profile and outflow temperatures series collected from the physical model in the General Reservoir Hydrodynamics flume. CE-QUAL-W2 has since been modified from this early form in numerous ways including incorporation of higher order transport schemes, additional vertical turbulence algorithms and implicit solutions for effects of vertical eddy viscosity to note only a few of the hydrodynamic optimizations. Among these modifications, the model has undergone many other rewrites and additions to address emerging applications and higher order water quality constituent models that will not be addressed within this assessment. This research project investigates the performance of the current version (v4.5) of CE-QUAL-W2 in matching the experimental results presented from within the Technical Report documenting the physical study and model review.
