Impact/Purpose:
The purpose of this work is to evaluate the challenges to applying an geospatial nitrogen retention model to all watersheds of the US.
Description:
The N-Sink tool was created to provide a useful and accessible means for local land use managers to explore the relationship of land use in their towns and counties to nitrogen pollution of their waters. N-Sink focuses on three types of landscape N sinks: wetlands, lakes/ponds/reservoirs, and stream reaches. N-Sink uses the best available science on landscape-nitrogen interactions, plus widely available basic datasets for hydrography, soils and land cover, to highlight major sources and sinks of nitrogen within a catchment context.The focus of this Science in Action brief is to explore the technical pros and cons of applying N-Sink to other geographic areas.
