The stream segments available here were extracted from a previous application of the Precipitation Runoff Modeling System (PRMS) in the Apalachicola-Chattahoochee-Flint River Basin by LaFontaine and others (2013). A Geographic Information System (GIS) file for the stream segments is provided as a shapefile with attribute seg_id identifying the numbering convention used in the PRMS models of the upper Chattahoochee River Basin in northeast Georgia. These GIS files represent the watershed area upstream of U.S. Geological Survey streamgage 02335000.

The upper Chattahoochee River Basin in northeast Georgia was modeled to produce seven example simulations of streamflow for demonstration of enhancements to the Precipitation Runoff Modeling System (PRMS). These data document the PRMS parameter files and input data files used in each of these simulations. Input files for the following simulations are included: 1) a baseline simulation of the existing model (includes HRU summary and basin variables output modules, and updates to depression storage), 2) a simulation using the dynamic parameters enhancement, 3) a simulation that generates an initial conditions file, 4) a simulation that uses a previously generated initial conditions file, 5) a simulation that uses the flow replacement option in the new muskingum_lake module, 6) a simulation that uses the flow through option in the new muskingum_lake module, and 7) a simulation that uses the new water use module.

The stream segments available here are for seven applications of the Precipitation Runoff Modeling System (PRMS) in the Apalachicola-Chattahoochee-Flint River Basin (ACFB) by LaFontaine and others (2017). Geographic Information System (GIS) files for the stream segments in each of the seven model applications (whole ACFB, Chestatee River, Chipola River, Ichawaynochaway Creek, Potato Creek, Spring Creek, and Upper Chattahoochee River) are provided as shapefiles with attributes identifying the numbering convention used in the PRMS models of the ACFB.

This data release contains inputs for and outputs from hydrologic simulations of the upper Chattahoochee River Basin in northeast Georgia using the Precipitation Runoff Modeling System (PRMS). These simulations were developed to provide example applications of enhancements to the PRMS for the following topics: two new time-series input options (dynamic parameter module and water-use module), two new output options (Hydrologic Response Unit (HRU) summary output module and basin variables summary output module), and three updates of existing capabilities (stream and lake flow routing module, surface-depression storage and flow simulation, and the initial-conditions specification). These PRMS model input and output data are intended to accompany a U.S. Geological Survey Techniques and Methods report (Regan and LaFontaine, 2017); they include three types of data: 1) PRMS input parameter and data files, 2) PRMS output data files, and 3) GIS files of the model hydrologic response units and stream segments. This data release contains the following example simulations associated with the enhancements: 1) baseline (HRU summary and basin variables output modules, updates to depression storage), 2) dynamic parameter module, 3) initial conditions output, 4) use of initial conditions file, 5) stream and lake flow routing with the flow replacement option, 6) stream and lake flow routing with the flow through lake option, and 7) water-use module.

The Apalachicola-Chattahoochee-Flint River Basin (ACFB) was modeled to produce fourteen simulations of streamflow for demonstration of enhancements to the Precipitation Runoff Modeling System (PRMS); seven simulations without water use effects and seven simulations with water use effects. The seven simulations without water use were for 1) the whole ACFB basin (1982-2012), 2) the Chestatee River sub-basin (1982-2012), 3) the Chipola River sub-basin (1982-2012), 4) the Ichawaynochaway Creek sub-basin (1982-2012), 5) the Potato Creek sub-basin (1942-2012), 6) the Spring Creek sub-basin (1952-2012), and 7) the upper Chattahoochee River sub-basin (1982-2012). The seven simulations with water use effects were for the period 2008-2012. These data document the PRMS output data files from each of these simulations. Output files for the simulations include: 1) statvar files of streamflow for each stream segment, 2) annual streamflow statistic files, 3) nhru-summary files of the major water availability fluxes and storages of the coarse-resolution model (includes precipitation, recharge, actual evapotranspiration, runoff, and storage for the hydrologic response units (HRUs), and 4) a file of PRMS-simulated recharge mapped to MODFLOW groundwater cells using the PRMS map_results module for use as input to simulations developed by Jones and others (2017).
