Summary
This data release consists of the data used to develop SPAtially Referenced Regression On Watershed(SPARROW) attributes models for estimating loads of total phosphorus and total nitrogen in Tennessee streams. These data support the publication containing the Tennessee SPARROW models results (Hoos and others, 2019) and include model input used in the South Atlantic-Gulf Drainages and Tennessee River Basin (SAGT) nutrient SPARROW models (Hoos and McMahon, 2009; Garcia and others, 2011) as well as model input for river basins in Tennessee not included in the domain of the published SAGT SPARROW models. Also included in this data release are model coefficients, the software required to execute the Tennessee SPARROW models, and the model [...]
Summary
This data release consists of the data used to develop SPAtially Referenced Regression On Watershed(SPARROW) attributes models for estimating loads of total phosphorus and total nitrogen in Tennessee streams. These data support the publication containing the Tennessee SPARROW models results (Hoos and others, 2019) and include model input used in the South Atlantic-Gulf Drainages and Tennessee River Basin (SAGT) nutrient SPARROW models (Hoos and McMahon, 2009; Garcia and others, 2011) as well as model input for river basins in Tennessee not included in the domain of the published SAGT SPARROW models. Also included in this data release are model coefficients, the software required to execute the Tennessee SPARROW models, and the model output for all streams in Tennessee. Each data set is listed in this data release with an accompanying file containing metadata for the dataset. For additional details, please refer to the README.txt file.
These two scenario calculator files contain the total nitrogen and total phosphorus SPARROW model input data, model coefficients, and model results obtained by the USGS/TDEC collaboration for Tennessee watersheds, described in Hoos, Wang, and Schwarz (2019). The model results include catchment-level predictions of nutrient load and aggregated-to-HUC10 nutrient load for pre-selected watersheds, but do not include the model results of routing load through each stream reach. The files can be used to search and retrieve model results for specific catchments and HUC10 units and to evaluate change in nutrient load as a result of source-change scenarios This zip file contains 1 file and three subdirectories (nitrogen_calculator, phosphorus_calculator, and reports).
