Webinar | Unraveling Complexity through Fate and Transport Numerical Simulations in a Tidally-Influenced, Density-Driven Flow Regime
April 12 @ 12:30 pm - 1:30 pm EDT
Overview
Join us on April 12, 2023 for a technical webinar regarding Unraveling Complexity through Fate and Transport Numerical Simulations in a Tidally-Influenced, Density-Driven Flow Regime.
Background/Objectives
Complex and highly-variable coastal plain environments, such as those found at the project site, are difficult to characterize hydrogeologically and therefore difficult to remediate. The site’s hydrogeologic complexities include a multilayered aquifer system, tidal influences, density-driven flow, and an adjacent river. Site-specific MODFLOW and SEAWAT finite difference numerical models were used to resolve those complexities and improve remedial decisions.
Approach/Activities
A groundwater flow model was developed, calibrated, and sensitivity tested to provide hydrogeologic support for remedial design scenarios at the site. MODFLOW-2005 was used for flow only simulations, while density effects were simulated by SEAWAT.
Results/Lessons Learned
The modeling process advanced understanding of the hydrogeologic system at the site, improved the conceptual site model, and resolved complex flow conditions not previously recognized. Through the development of MODFLOW and SEAWAT finite difference numerical models, this project represents how the modeling process provides a quantifiable link for challenging hydrogeologic conditions and combining complicated processes.
