Surface-water model archive for simulating flood-inundation extents for the Muddy River, near Moapa, Nevada

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-05-23T00:00:00Z
This model archive contains all relevant files to run and document the Hydrological Engineering Center-River Analysis System (HEC-RAS) coupled one and two-dimensional hydraulic model used to simulate flood-inundation extents for the Muddy River, near Moapa, Nevada. The HEC-RAS model was applied to simulate flood-inundation extents for a current (2019) levee location and for a new location location proposed as part of a river restoration plan. The model archive includes information on: 1) stage-streamflow rating used for model calibration (calibration_targets); 2) the model run and output files (model_files); and 3) the 32-bit executable installation file for HEC-RAS 6.1 used to run the simulations (HEC-RAS_61.Setup.exe); 4) the modeling software version and website (model-software-version.txt); 5) the model bounding box coordinates (modelgeoref.txt); 6) an overview of how to run the model and all the files and folders in SWmodel_Archive.zip (README.txt).
