Simulations of Groundwater Nitrogen Transport in the Long Island, New York Aquifer System Under Potential Nitrogen Management Scenarios

This data release contains simulation results from twenty-three (23) transient inset numerical models of the eastern part of Long Island, New York that includes the Peconic River, and estuaries around the North and South Fork. The models simulate nitrogen concentrations in the aquifer and nitrogen loads to surface water bodies from 2020-2120 under different nitrogen inputs that represent potential nitrogen management decisions. Simulations are based on the inset MODFLOW 6 (Hughes and others, 2017) flow and transport models documented in Jahn and Walter (2024a & b).
