Groundwater Flow Modeling - Long Island, New York
Numerical models provide a means to synthesize existing hydrogeologic information into an internally consistent mathematical representation of a real system or process, and thus are useful tools for testing and improving conceptual models or hypotheses of groundwater flow systems. The goal of this effort is to develop a regional model for the Long Island aquifer system to simulate changes in water...
The Use of Solute-transport Methods to Estimate Time-varying Nitrogen Loading Rates to the Peconic Estuary Resulting from Wastewater and Fertilizer Inputs to Groundwater in Suffolk County, New York (Peconic Solute Transport)
Problem The Peconic Estuary of eastern Long Island, New York, is undergoing development as the region transitions from a rural area dependent on agriculture and tourism to a suburban one with a larger year-round population. The glacial and coastal-plain sediments underlying Long Island comprise a sole-source aquifer system that supplies the region’s communities with potable water. The...
