TOMAWAC - Wave propagation in coastal areas



Wave propagation off  Paluel nuclear power station


TOMAWAC is used to model wave propagation in coastal areas. By means of a finite-element type method, it solves a simplified equation for the spectro-angular density of wave action. This is done for steady-state conditions (i.e. with a fixed depth of water throughout the simulation).


Simple to use

TOMAWAC is particularly simple to use. It can take into account any of the following physical phenomena:

  • Wind-generated waves
  • Refraction on the bottom
  • Refraction by currents
  • Dissipation through bathymetric wave breaking
  • Dissipation through counter-current wave breaking

At each point of the computational mesh, TOMAWAC calculates the following information:

  • Significant wave height
  • Mean wave frequency
  • Mean wave direction
  • Peak wave frequency
  • Wave-induced currents
  • Radiation stresses

Application to coastal engineering


Validated with a variety of test cases and already used in numerous studies, TOMAWACis ideal for engineering projects: design of maritime structures, sediment transport by waves, current studies, etc.

Integrated into the TELEMAC-MASCARET system

Like all the TELEMAC simulation modules, TOMAWAC has the benefit of the system's powerful mesh generation and results display functions.

It is also easy to link TOMAWAC and the hydrodynamic or solid transport modules, and to use the same computation grid for various modules (TELEMAC-2D, SUBIEF-2D, TOMAWAC, etc.).

Like all the modules of the TELEMAC system, TOMAWAC was developed in accordance with the quality assurance procedures followed in Electricité de France's Studies and Research Division. The software is supplied with a complete set of documents: theoretical description, user's manual and first steps, validation file, etc.
