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