Model Contaminant Transport. Inform Remediation Decisions.

TIGSED simulates how contaminants move through sediment—both at the surface and below—to support high-impact remediation decisions. Designed for flexibility and speed, this proprietary method captures key processes like sediment deposition, groundwater upwelling, and contaminant decay to deliver a clear picture of site dynamics.

With fine resolution and fast run times, TIGSED helps teams understand risk, compare cleanup strategies, and plan with confidence. It supports side-by-side analysis of MNR, EMNR, capping, and dredging across complex river systems—accounting for site variability and long-term outcomes. TIGSED also integrates with hydrodynamic models and CapSIM to enhance design precision and cost-effectiveness.
