RSPARROW Modeling Tool used to Estimate Total Nitrogen Sources to Streams and Evaluate Source Reduction Management Scenarios in the Grande Basin, Brazil
Description
The data release documents the development of a hybrid
(statistical-mechanistic) SPARROW (SPAtially Referenced
Regression On Watershed attributes) model of long-term
mean annual total nitrogen applied to streams and rivers of
the Grande River Basin, Brazil. The model coupled observed
long-term average total nitrogen loads at monitoring locations
with additional explanatory variables (e.g., landscape sources,
wastewater treatment plant inputs, and in-stream nitrogen losses)
to estimate nitrogen loading to all reaches in the modeled area.
The model was applied to estimate the effects of hypothetical
changes in land use and discharge from wastewater treatment
on in-stream total nitrogen loading, as described in the journal
article. This USGS data release contains all of the input and output
files for the execution of all of the models described in the
journal article (see Table 1; https://doi.org/10.3390/w12102911).
An R script is provided that allows users to execute the
model.
