At-site flood-frequency statistics for regulated streamgages in Virginia and West Virginia, 2025
This child item contains input files and output files for 86 regulated streamgages in and near Virginia and West Virginia processed using PeakFQ v7.5.1 for the 2025 flood-frequency analysis. Additionally, results were extracted from the input and output files for in each streamgage and summaries were generated. This dataset includes:
1) "Regulated_Frequency_Analysis.zip": A subdirectory containing published annual peaks in WATSTORE format (*.pkf), specifications used for processing in Program Specification File format (*.psf), the output text file containing computation results (*.prt), and the export text file (*exp). At-site skew was used to compute these results.
2) Table_5_Regulated_Frequency_Specs.txt: Contains a summary of the specifications and statistics for at-site frequency analyses for 86 streamgages on regulated streams in Virginia and West Virginia for annual peak streamflows including period of record, record length, skew specifications, thresholds and counts of PILFs, value, significance, and slope of the Mann-Kendall trend test; mean, median, station skew, and MSE of station skew.
3) Table_6_Regulated_Frequency_Summary.txt: Contains a summary of the results of valid at-site frequency analyses for 86 streamgages on regulated streams in and near Virginia and West Virginia for annual peak streamflows including flow and variance values for the 0.995, 0.667, 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 annual exceedance probabilities.
