ARTEMIS is integrated in the hydro-informatics TELEMAC system. ARTEMIS is a scientific software dedicated to the simulation of wave propagation towards the coast or into harbors, over a geographical domain of about few sq. km. The domain may be larger for simulation of long waves or resonance. The frequency dependence and directional spreading of the wave energy is taken into account by ARTEMIS. The computation retrieves the main wave characteristics over the computational domain: significant wave height, wave incidence, orbital velocities, breaking rate,...

ARTEMIS solves the Berkhoff's equation or Mild Slope Equation through finite element formulation and a computation mesh of triangular elements. The Mild Slope Equation has been extended to integrate dissipation processes. With a consistent set of boundary conditions, ARTEMIS is able to model the following processes:

• Bottom refraction
• Diffraction by obstacles
• Depth induced wave breaking
• Bottom friction
• Full or partial reflections against walls, breakwaters, dikes , ...
• Radiation or free outflow conditions

The results are post processed with the RUBENS module that offers the user a wide range of graphs for analyzing the results of simulations:

• Isovalue curves and coloured areas
• Vector fields
