Summary
This model archive contains the data and software application necessary to simulate two-dimensional hydraulic parameters along a 1.6 kilometer study reach of the Sacramento River near Glenn, California. The iRIC modeling system and the NAYS2DH solver were used to simulate three river flows (90, 191, and 255 cubic meters per second) and provide spatially distributed depths, velocities, and water-surface elevations along the study reach. The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files more manageable. The first child item in the archive is the hydraulic model software application. The second child item includes the topographic data used to construct [...]
Summary
This model archive contains the data and software application necessary to simulate two-dimensional hydraulic parameters along a 1.6 kilometer study reach of the Sacramento River near Glenn, California. The iRIC modeling system and the NAYS2DH solver were used to simulate three river flows (90, 191, and 255 cubic meters per second) and provide spatially distributed depths, velocities, and water-surface elevations along the study reach. The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files more manageable. The first child item in the archive is the hydraulic model software application. The second child item includes the topographic data used to construct the model grid as well as field measurements of water-surface elevation and depth-averaged velocity used to calibrate the hydraulic roughness parameter. The third child item provides output from the NAYS2DH model using various Manning's n roughness values. A comparison of the root mean square errors between the model simulation and field measurements is included for each roughness parameter. The fourth child item includes model output for the three river flows that were simulated to support the manuscript.

Purpose
This dataset is a model archive whose purpose is to support the analysis associated with a paper describing a framework for Simulating Hydraulics and Images for Velocimetry Evaluation and Refinement (SHIVER), intended to facilitate development and testing of image-based river velocimetry algorithms. A reach of the Sacramento River near Glenn, California, was used as a case study to illustrate the application of this approach in the context of a particular study site.
