TELEMAC-2D

Two-dimensional free surface flow modelling

TELEMAC‑2D solves the two‑dimensional Saint‑Venant equations for free‑surface flows using the finite element or finite volume method and a computational mesh of triangular elements. It can perform simulations in transient and stationary conditions. TELEMAC-2D can take into account various physical phenomena:

  • Propagation of long waves, taking into account non-linear effects
  • Bed friction
  • Influence of Coriolis force
  • Influence of meteorological factors: atmospheric pressure and wind
  • Turbulence
  • Torrent and river flows
  • Influence of horizontal temperature or salinity gradients on density
  • Cartesian or spherical coordinates for large domains
  • Dry areas in the computational domain: intertidal flats and flood plains
  • Current entrainment and diffusion of a tracer, with source and sink terms
  • Monitoring of floats and Lagrangian drifts
  • Treatment of singular points: sills, dikes, pipes.
  • Advection-diffusion of tracers such as temperature, salinity or concentrations of material substances.
