Results of the investigation will be disseminated through a final online report in the USGS Scientific Investigations Report series, a link to an online file archive where model data may be publicly accessed, and an online repository of geospatial layers and metadata. All numerical models used will be those developed by USGS and available publicly at http://water.usgs.gov/software/lists/groundwater
. The study products will document application of a groundwater-flow model to comprehensively delineate the ground-water recharge areas
associated with estuaries and streams of Long Island. The products will include:
• the flow model grid, including comparison of NACP/NAWQA grids and Long Island study area grid,
• maps and sections presenting the three-dimensional distribution of the hydrogeologic units,
• the present steady-state distribution of groundwater recharge,
• simulated potentiometric-surface and water-table maps of principal aquifers,
• statistics related to flow model calibration, sensitivity analysis, and model uncertainties, and
• recharge area delineations and associated traveltimes.
