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.

    Sacramento Soil Moisture Accounting Model (SAC-SMA)

    In this webinar, I will demonstrate a GoldSim implementation of the SAC-SMAmodel. This model is a continuous soil moisture accounting model with spatially lumped parameters that simulates runoff within a basin. The model divides the basin into lower and upper zones at different depths, and defines the distribution of moisture, i.e., tension water components (driven by evapotranspiration and diffusion) and free water components (driven by gravitational forces) in each of these two zones via a set of parameters. The model uses precipitation and temperature variables, along with parameters on soil moisture states and the basin’s relative permeability to estimate the amount of water that enters, is stored in, and leaves the basin.
