GoldSim Webinars
We offer free, monthly webinars to present GoldSim features and applications. Upcoming webinars are listed below. If you would like to be placed on our Webinar Mailing List to be reminded every month of the upcoming webinar, contact us.
All webinars are recorded (and posted to the site within a day or two), and these provide an excellent resource for learning about GoldSim features and applications.
Materials and video recordings of past webinars are available on our Webinar Archive Page.
Next Webinar: Linking GoldSim and EPA SWMM
Presented by: Jason Lillywhite
EPA SWMM is the industry standard for hydraulic modeling, yet its internal water quality engine can be limiting for practitioners who need to model complex contaminant behavior beyond simple percentage-based removal. In this session, I will demonstrate a tool that couples SWMM’s hydraulic calculations with GoldSim, providing direct access to Monte Carlo simulation and the Contaminant Transport (CT) Module. This integration allows SWMM to handle the physical routing of water while GoldSim provides the mathematical framework for tracking pollutant mass balance, advection, and dispersion.

By linking these two platforms, users can move to a mass-based modeling approach that tracks the cumulative accumulation of solids (TSS) within Low Impact Development (LID) features. We will walk through a "Treatment Train" case study where GoldSim uses the flow and volume data from SWMM to calculate the fate of pollutants like Zinc, accounting for how they partition and sequester within filter media over time. This workflow supports Monte Carlo simulations, enabling you to evaluate system performance across thousands of stochastic realizations to quantify probabilistic risks and maintenance requirements.
