The dynamics of rivers involve complex interactions between water, sediment transport, and bed geometry. River management depends on predicting the effects of these interactions, including channel migration and cross-sectional change, thermal and flow pattern effects from intakes and outfalls, and ecological effects of management strategies. FLOW-3D is widely used in the Water and Environment industry to address complex river dynamics and to predict fluvial behavior. In addition to solving free-surface flow patterns, FLOW-3D includes a broad selection of powerful physics packages that address most river management problems. Some examples of processes that are regularly modeled with FLOW-3D include thermal and saline transport and stratification, pollutant fate and transport (reactive and non-reactive), turbulent air entrainment and residence, and sediment transport (including erosion and deposition.
FLOW-3D is used to solve challenging design problems pertaining to water/civil infrastructure. This video shows a proof-of-concept simulation of the standing wave feature on the Trinity River in Dallas (inset). Accurate design iterations can be explored and achieved quickly, saving engineers both time and effort. Additionally, FLOW-3D‘s extensive multiphysics suite can be used to model associated processes such as sediment scour and air entrainment, which can further enable engineers to navigate design challenges.
