Evaluating cavitation and structural integrity where cracks might form due to extreme water pressure.
In the world of hydraulic engineering, few events are as catastrophic as the sudden failure of an embankment dam or levee. When water rises and spills over the crest of an earthen structure, the process of begins — an erosion sequence that can rapidly widen and deepen, leading to uncontrolled releases of reservoir water and devastating downstream flooding. Predicting exactly where and how this breach will start—whether due to a pre-existing crack, a localized weakness at the crest, or a geometric discontinuity on the dam's top—has become a critical area of focus. flow 3d hydro crack top
The top of a dam or spillway is rarely smooth. It has construction joints, cracks, roughness elements, and erosion scars. Flow-3D’s (Fractional Area/Volume Obstacle Representation) allows engineers to import real LiDAR scans or CAD models of a cracked crest without time-consuming mesh conforming. The porosity of the crack itself can be modeled, simulating water being injected into the crack top under extreme pressure. Predicting exactly where and how this breach will
Most CFD solvers struggle with the air-water interface, blurring the boundary. Flow-3D’s TruVOF (Volume of Fluid) method preserves the sharp discontinuity at the water surface. For a crack top simulation, this means the model accurately predicts the exact point where flow detaches from the crest, the thickness of the falling nappe, and the air entrainment rate. Across the industry
Hydraulic fracturing simulations can be highly complex, requiring detailed geological data and significant computational power.
Across the industry, FLOW-3D HYDRO is recognized as an industry leader in free-surface flow modeling and is used by dam professionals worldwide to address a wide range of design problems [7†L4-L6][4†L5-L6]. From the simplest ogee to the most complex geometric configurations, the software's strengths are ideally suited for dams and spillways [7†L10-L11].
