FLOW-3D is an accurate and robust free-surface CFD package, the ideal tool for modeling dam and spillway structures. Dam safety professionals and design engineers around the world rely on the efficiency and accuracy of FLOW-3D for quantifying all aspects of dam and spillway design, operation, and maintenance.
FLOW-3D makes it easy to generate rating curves and detailed velocity profiles for complex spillways, including the effects of air entrainment and transport. FLOW-3D also enables the quantification of structural stresses (pressure and shear forces) during normal and extreme operations, including transient effects due to gate operation. FLOW-3D i widely used to confirm the hydraulic performance of proposed spillway designs and to help professionals meet dam safety requirements.

Studies by Manitoba Hydro indicated
that lateral contraction effects in the three-gated sluiceway at its Wuskwatim
hydroelectric project in northern Manitoba could be substantially reduced if
minor design changes were made. As a result, an approximate 5% increase in spillway
capacity at the design head was realized. This allowed designers to raise
the spillway invert and reduce overall construction costs.
