Simulation of Groundwater Flow in the Long Island, New York Regional Aquifer System for 2010 Daily Recharge Conditions

This model archive documents a transient groundwater-flow model that simulates hydrologic conditions in the Long Island aquifer system for the year 2010, using the U.S. Geological Survey groundwater modeling software MODFLOW 6 (Langevin and others, 2017). The groundwater model is a derivative of the conditioned model documented in Jahn and others (2024), and described in Walter and others (2024), which simulates transient 1900-2019 annual conditions to simulate long-term groundwater conditions. To capture short-term variations in aquifer conditions, this model utilized daily recharge and monthly average pumping rates for 2010. This model was not calibrated to match daily or seasonal observations, and care should be used in interpreting daily recharge terms and simulated head responses. Application of this model for site specific study may require additional model testing.
