This polygon shapefile represents model simulated flood-inundation extents for the Muddy River, near Moapa Nevada. A flood frequency analysis was performed at USGS streamgage 09416000 - Muddy River near Moapa, Nevada, to estimate the 50, 20, 10, 4, 2, and 1-percent annual exceedance probability (AEP) flood streamflows. The flood-inundation extents for the 50-, 20-, 10-, 4-, 2-, and 1-percent AEP floods were simulated for the current levee location in 2019 and for the new levee location of the proposed restoration. One model simulation represents the levee at its current (existing) location in 2019 on the east bank of the river and referred to as ‘current conditions (2019).’ A second model simulation removes the...

This U.S. Geological Survey data release consists multiple datasets used to simulate the extents of flood inundation along the Muddy River, near Moapa, Nevada. Flood-inundation extents equal the maximum area of flood inundation and were estimated using a coupled one-dimensional (1D) and two-dimensional (2D) hydraulic model. The modeled extents represent six annual exceedance probabilities simulated for the current (2019) levee location adjacent to the Muddy River and a new levee location associated with a proposed restoration of a selected reach along the Muddy River. The data release includes: 1) a polygon dataset of the flood-inundation extents (MuddyRiver_Flood_Inundation_p.shp); 2) a zip file containing all...
This point shapefile contains positional data for 2,205 locations at the Muddy River, near Moapa, Nevada, April 1 to August 9, 2019. Positional data were collected using either a single-base real-time kinematic (RTK) global navigation satellite system (GNSS) or a total station. The survey data primarily were used to define 105 cross-sections, with a secondary use as vertical precision verification for lidar data.

This polygon shapefile represents the boundaries of the current (2019) and proposed levee locations used to simulate flood-inundation extents for the at Muddy River, near Moapa, Nevada. The new levee location is proposed as part of a river restoration plan for selected reaches of the Muddy River.

This point shapefile contains positional data for seven static reference locations collected at the Muddy River, near Moapa, Nevada, March 29 to August 9, 2019. Positional data were collected at seven temporary benchmarks using 14 single-baseline online positioning user service – static (OPUS-S) global navigation satellite system (GNSS) surveys. Data were collected using Leica Viva GS14 or TopCon GR-3 GNSS receivers. Processing of static observations was done using the National Geodetic Survey (NGS) online positioning user system (OPUS).

This archive contains all relevant files to run and document the flood-frequency analysis using the PeakFQ 7.3 software for estimating the annual exceedance probability streamflows for U.S. Geological Survey streamgage 09416000 - Muddy River near Moapa, Nevada. The archive includes: 1) the PeakFQ input file (09416000_peak.txt); 2) the PeakFQ output file (09416000_PEAK.PRT); 3) the PeakFQ specifications file (09416000_PEAK.PSF); 4) the PeakFQ input data graph file (09416000_inp.EMF); 5) the PeakFQ Annual exceedance probability plot file (094196000.EMF); 6) the summary table documenting the flood-frequency (09416000_Flood_Frequency.xlsx);
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);...
