Short Description of Functionality

The two-dimensional finite element numerical model TELEMAC-2D can be used to simulate flow and transport processes in different free-surface flow problems. The following list of physical processes are taken into account by TELEMAC-2D:

• shallow water equations
  • local acceleration (inertia)
  • advective acceleration
  • Coriolis acceleration
  • barotropic pressure gradient
  • baroclinic pressure gradient (depth integrated)
  • atmospheric pressure gradient
  • turbulent diffusion and dispersion
  • bottom friction
  • wind friction

Turbulence can be optionally calculated using a K-Epsilon turbulence model.

• advection-diffusion equation
• Boussinesq-equation

With the aid of the numerical model TELEMAC-2D the following physical quantities can be calculated:

• depth-averaged scalar velocity
• depth-averaged velocity in x-direction
• depth-averaged velocity in y-direction
• surface wave celerity C
• water depth
• free surface elevation
• bathymetric depth (bottom)
• Froude number
• Courant number
• depth-averaged scalar flowrate
• depth-averaged flowrate in x-direction
• depth-averaged flowrate in y-direction
• depth-averaged tracer concentration
• depth-averaged turbulent kinetic energy
• depth-averaged turbulent dissipation
• depth-averaged turbulent viscosity

TELEMAC-2D has been developed from Laboratoire d'Hydraulique der EDF-DER (Chatou, Paris). A comprehensive description of the system is available in "TELEMAC-2D Modelling System - Users Manual".
