Mathematical Model TELEMAC-2D
From BAWiki
Short Description
The mathematical model TELEMAC-2D is based on the finite element approach. TELEMAC-2D was designed to solve several depth-integrated transient nonlinear partial differential equations (pde's). The model is actually used to study one ore more of the following physical processes:
- transport of water (conservation of the water mass)
- transport of linear momentum (conservation of linear momentum)
- transport of turbulent kinetic energy and turbulent kinetic energy dissipation (conservation of the turbulent kinetic energy)
- transport of salinity (conservation of the dissolved salt mass)
TELEMAC-2D was developed by Laboratoire Nationale d'Hydraulique from Electricté de France, Direction des Etudes et Recherches (EDF-DER), Chatou-Paris. TELEMAC-2D has been successfully installed in the year 1994 at BAW-DHs computers. It has been integrated into BAW-DHs numerical modelling toolbox and is now used on a routine basis in the context of different real-world projects concerning estuarine flow and transport processes.
There are several documents available to the user which give a comprehensive overview about the capabilities and limitations of the model.
