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...
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...
Flowduration statistics at the 99th, 98th, 95th, 90th, 80th, 70th, 60th, and 50th percent exceedance probabilities and annual nday lowflow statistics for the 1, 7, 14, and 30day mean low flows with 2year (0.5 nonexceedance probability), 5year (0.2 nonexceedance probability), and 10year (0.1 nonexceedance probability) recurrence intervals were computed for 28 selected streamflow gaging stations in Puerto Rico. The 28 selected streamflow gaging stations were required to have 10 or more years of daily mean streamflow data through water year 2018. The flowduration statistics and nday lowflow frequencies were computed using the U.S. Geological Survey program, SWToolbox. Regional regression equations were...
