FLOW-3D is a modeling tool that offers unique free surface modeling capabilities, as well as a vast array of advanced models that are tightly coupled to free surface hydraulics to include features such as scour and sediment dynamics, particulates, air entrainment, bubble dynamics, density flows, chemistry, and many more. Following a series of webinars that have focused on various aspects of civil infrastructure and environmental flow modeling, this presentation offers a comprehensive review of the modeling options that are currently available to water resource engineers using FLOW-3D.
