Numerical modeling of hydrodynamic accidents: Erosion of dams and flooding of territories

A mathematical and numerical model of the joint dynamics surface water traction sediment is built, which takes into account nonlinear fluid bottom deformation. The waters described by equations Saint-Venant, taking spatially inhomogeneous distribution terrain. transport loads Exner equation, generalized to case a parameters underlying surface. For integration Saint-Venant equations, stable well-tested CSPH-TVD method second order accuracy used, parallel CUDA algorithm implemented as software package “EcoGIS-Simulation” for high-performance computing on supercomputers with graphic coprocessors (GPU). Hydrodynamic modeling processes erosion enclosing dam real hydraulic facility flooding adjacent territories has been carried out. penetration zones, formed result development accident at tailing dump, have determined. Based results obtained, it was concluded that proposed can be more universal.
