Dredging Impacts

Dredging impact and dredge-plume assessment with open-source EFDC+ — sediment transport fully coupled to toxics.

Assessing Dredging Impacts

Dredging keeps ports and channels open, but it can stir up contaminated sediments, alter circulation, and affect sensitive marine habitats. Assessing and managing these impacts requires flexible, open-source tools that work across a range of regulatory settings.

EEMS Capabilities

EEMS is widely used for dredging impact assessments. EFDC+‘s open-source status makes it accessible in cases where proprietary tools like MIKE 3 cannot be used. Both sediment models are fully coupled to toxics simulation, enabling assessment of contaminated material transport alongside standard dredge plume work.
