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.
