Join Flow Science engineers on May 15 at 1:00 pm for a webinar that will use the well-documented St. Francis Dam as a demonstration.

• How fully three dimensional hydrodynamic solutions in the dam near field are obtained at very reasonable computational costs.
• How it is critical to capture the complex initial (and multiple) transitions between super-critical and sub-critical flow regimes in order to determine accurate downstream flood wave heights.
• FLOW-3D's shallow water model wave height and arrival time sensitivity to mesh refinement.
• FLOW-3D's shallow water model wave height and arrival time sensitivity to drag coefficient/surface roughness.
• How FLOW-3D's General Moving Object model can be used to evaluate the distance traveled by broken segments of the dam as they are lifted downstream and float to their resting positions.

Special attention will be given to the topic of sub- and super-critical flow transitions and their relation to downstream flood extents. We will also provide the detail of the simulation setup and the computational costs associated with the different approaches available to FLOW-3D modelers.

The webinar will be presented by John Wendelbo, engineer with Flow Science.
