Development and Calibration of a 100-Year, Transient, Saltwater Intrusion Model for Long Island, New York
A groundwater flow model of the aquifer system beneath Kings, Queens, Nassau and Suffolk counties on
DYNSWIM, a 3-dimensional, finite-element, dual-phase freshwater and saltwater flow code was used in this study. DYNSWIM is part of the DYNSYSTEM suite of groundwater modeling software and was developed for use in coastal aquifer studies. The model adequately simulates the movement of the saltwater wedge, as well as water level fluctuations associated with changes in pumping and groundwater recharge, over time.
Matthew Gamache, PE, CDM Inc. Mr. Gamache is a water resources engineer who specializes in subsurface hydrologic and contaminant transport modeling. These models have been used to assess groundwater flow paths, travel times, and contaminant concentrations for litigation support, delineation of drinking water protection zones, and design of groundwater remediation systems.
Robert Fitzgerald, PE, CDM Inc. Mr. Fitzgerald is a Senior Groundwater Modeler who has been responsible for numerous studies of groundwater flow and dissolved and separate phase contaminant transport in aquifers. Mr. Fitzgerald also has extensive experience in hydrology, hydraulics and water resources management, emphasizing the application of computer simulation models. He has been responsible for the use of models in analyzing and developing programs for groundwater management and remediation, flood alleviation, reservoir yield augmentation and water quality assessment.
Kristina K. Masterson, PE, CDM Inc. Ms. Masterson is a water resources engineer who specializes in groundwater flow and contaminant transport model simulation analysis. Ms. Masterson has conducted groundwater flow and mass transport modeling studies for site environmental assessment, remediation investigation and design, remediation performance evaluation, and water resources management projects. During the 20 years that she has worked in the water resources engineering field, Ms. Masterson has successfully applied numerical groundwater flow and mass transport models to study groundwater flow patterns and contaminant mass transport characteristics in many different hydrogeological settings.
