Hydrodynamic model of the Colorado River, Glen Canyon Dam to Lees Ferry in Glen Canyon National Recreation Area, Arizona: tables of model results and accuracy assessment

These data were compiled to provide a resource for other researchers interested in water-surface elevations and flow velocity across a wide range of discharge in the study reach for the project. Objective(s) of our study were to construct a two-dimensional hydrodynamic model for the 15.8 mile tailwater reach of the Colorado River in Glen Canyon between Glen Canyon Dam and Lees Ferry, Arizona. These data represent the results of the two-dimensional modeling effort with each data table (50) including the results of each run of the model. Additionally, other data represent a comparison of modeled water surface elevations to measured water surface elevations for historic Bureau of Reclamation cross sections in the study reach. These data were generated by U.S. Geological Survey personnel on PC-based computers in Flagstaff, Arizona in 2019 using the FaSTMECH solver in the iRIC modeling interface (https://i-ric.org/en/solvers/fastmech/). These data can be a useful resource to researchers interested in water-surface elevations, shoreline extents, water depths, velocities, and other hydraulic characteristics across a range of discharges within the 15.8 mile tailwater reach of the Colorado River in Glen Canyon between Glen Canyon Dam and Lees Ferry, Arizona.
