Summary

This U.S. Geological Survey data release contains datasets that combine past data with future projections of nitrogen sources and nitrogen export to the Chesapeake Bay watershed for the years 1950-2050. To help understand the effect of human and environmental changes over this time period, data for nitrogen sources from wastewater, agricultural fertilizer and manure, and atmospheric deposition are combined with datasets of population and land use. These datasets were used in conjunction with a previously calibrated SPAtially Referenced Regression On Watershed attributes (SPARROW) modeling tool to estimate the mean annual loads of total nitrogen to the Chesapeake Bay and nontidal stream reaches in the watershed at a decadal timestep [...]

Purpose

The datasets were created to help understand how changes in land use, fertilizer use, manure production, and municipal wastewater discharges of nitrogen would affect nitrogen export from the watershed to the Chesapeake Bay. These datasets can be used to support the past and future understanding of nitrogen inputs in the Chesapeake Bay watershed.
