A generalized least squares (GLS) technique was used with atsite nday lowflow time series and frequencies, from SWToolbox (Kiang and others, 2018), and 14 basin characteristics (basin perimeter, drainage area, maximum basin elevation, mean total annual reference evapotranspiration, groundwater head, length of longest flow path, minimum basin elevation, runoffcurve number, relief, ruggedness, slope ratio, percentage of hydrologic soil type B, available water capacity, and total length of streams in a basin) for 28 selected streamflow gaging stations in Puerto Rico to calculate regional nday lowflow frequency regression equations for ungaged stream locations. The GLS approach assigns weights based on uncertainty...

This file (wymt_ffa_2021B_WATSTORE.txt) contains peakflow input data for PeakFQ for peakflow frequency analyses for selected streamgages based on data through water year 2021. The file format is called WATSTORE (National Water Data Storage and Retrieval System) available from NWISWeb (http://nwis.waterdata.usgs.gov/usa/nwis/peak).

An ordinary least squares (OLS) technique was used with atsite flowduration exceedance probabilities, from SWToolbox (Kiang and others, 2018), and 14 basin characteristics (basin perimeter, drainage area, maximum basin elevation, mean total annual reference evapotranspiration, groundwater head, length of longest flow path, minimum basin elevation, runoffcurve number, relief, ruggedness, slope ratio, percentage of hydrologic soil type B, available water capacity, and total length of streams in a basin) for 28 selected streamflow gaging stations in Puerto Rico to calculate regional flowduration regression equations for ungaged stream locations. The final flowduration regression equations were developed in R (R...

A comma separated values (csv) file that is a snapshot of the U.S. Geological Survey peak flow file on November 14, 2016. The file lists agency, station identification, water year, peak date, peak values, peak qualification codes, gage height values, gage height qualification codes, and year of last peak for all stream gaging stations for which peak streamflow has been recorded.
