Estimated daily mean streamflows for HUC12 pour points in the southeastern United States, 1950-2009
February 20, 2020
This data release contains estimated daily streamflow values for 9,203 12-digit hydrologic unit codes (HUC12s) in the southeastern United States for the period 1950-2009. The files are provided in text format, which can be used in R and in other programs. The 'Site Info' folder contains 18 files with streamgage information and the 'Daily Values' folder contains 18 files with predicted daily streamflow values for a given HUC12. Each of the datasets contains 500, 501, or 704 HUC12s, respectively. Data preparation and analysis of the predicted streamflow values were scripted in RStudio. Results of the analysis will be used to quantify streamflow alterations across the study area and will be published in a separate product.

Generalized additive model estimation of no-flow fractions and L-moments to support flow-duration curve quantile estimation using selected probability distributions for bay and estuary restoration in the Gulf States
Censored and uncensored generalized additive models (GAMs) were developed using streamflow data from 941 U.S. Geological Survey streamflow-gaging stations (streamgages) to predict decadal statistics of daily streamflow for streams draining to the Gulf of Mexico. The modeled decadal statistics comprise no-flow fractions and L-moments of logarithms of nonzero streamflow for six decades (1950–2009).

RESTORE/fdclmrpplo, Source code for estimation of L-moments and percent no-flow conditions for decadal flow-duration curves and estimation at level-12 hydrologic unit codes along with other statistical computations
The RESTORE/fdclmrpplo repository contains R language source code used for estimation of the L-moments and percent no-flow conditions (no-flow fractions) for decadal flow-duration curves and estimation at streamgages and level-12 hydrologic unit codes using generalized additive models and censored generalized additive models. The source code is designed to streamline the workflow for the Gulf Coas
