Numerical modeling, experimental characterization of gaps in embankment dams and dikes

To reduce potential negative impacts originated by dam and dike failure, reliable simulation tools are needed. This Project aims at accomplishing this goal by assembling and validating a suite of mathematical simulation tool for embankment erosion and failure by overtopping encompassing both hydraulic and geotechnical phenomena in the conceptual model. For validating the numerical simulation tool, a set of laboratory tests will be conducted to understand the mechanics of breach evolution.

• New generation 3D numerical model for fluid-sediment mixtures based on a conceptual framework on embankment breaching.

• Comprehension of the flow hydrodynamics near the breach based on experimental tests of embankment failures based on 3D printing of the breach
• Deepening of knowledge on novel instrumentation, visualization and measuring techniques for detailed characterization of breaching processes
• Database on embankment dam failures resulting from intense laboratory work
• Hybrid numerical model for embankment’s breaching failure combining 3D meshless solver and 2D modelling
