Input and selected output files from USGS WREG software for 346 selected streamgages in New Mexico and parts of Arizona, Colorado, Oklahoma, Texas, and Utah that were used to develop regional regression equations to estimate the magnitude and frequency of floods at ungaged locations in New Mexico
The U.S. Geological Survey (USGS), in cooperation with the New Mexico Department of Transportation, estimated the magnitude and frequency of floods corresponding to the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs; otherwise known as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods, respectively) for 346 selected streamgages in New Mexico and parts of Arizona, Colorado, Oklahoma, Texas, and Utah using data through water year 2020. An updated regional flood skew, -0.145, standard error 0.454, was computed for the study area and, where appropriate, was used to weight the at-site skew in flood-frequency analyses. The results of the frequency analyses, regional flood skew, and a suite of basin characteristics from the USGS StreamStats application (Ries and others, 2008) were used in generalized least-squares (GLS) regression, conducted using version 3.0 of USGS weighted regression (WREG) software (Farmer, 2021; Eng and others, 2009), to generate regression equations for each of nine flood regions that predict discharges corresponding to selected AEPs at ungaged locations on unregulated streams in the study area. The methods and results of the study are published in the parent report (Bell and others, 2022, https://doi.org/10.5066/XXXXXXXX).
This dataset includes the following input files for USGS WREG software, located in the "WREG_input" folder within the "WREGfiles.zip" directory: a text file of basin characteristics for all 346 selected streamgages in the study area("BCHAR_WREG.txt") and a PeakFQ output (*.PRT) and export (*.EXP) file for each streamgage. The following eight WREG output files, located in the "WREG_output" folder within the "WREGfiles.zip" directory, are included for each of the 8 selected AEPs for each flood region (1 and 4, 2 and 9, 3 and 8, 5, 6, and 7): "coef.txt", "CoVarMat.txt", "FitandResid.txt", "modelInput.txt", "outputRaw.rda", "PerformanceMetrics.txt", "ResLevInf.txt", and "Weighting.txt".
