TRITON

Boussinesq-type wave model for coastal and harbour applications

TRITON is a Boussinesq-type wave model capable of computing the wave dynamics in great detail. It simulates intra-wave properties such as individual wave height transformations (including breaking), wave skewness and wave asymmetry, and drift velocities for arbitrary bathymetries. TRITON is designed for coastal as well as harbour applications.

TRITON incorporates the following processes:

• Dispersion
• Diffraction
• Refraction
• Shoaling
• Wave breaking
• Wave run-up
• Nonlinear wave-wave interactions (generation of higher and lower harmonics). This is of importance for, among others, seiches generation in harbours and surfbeat
• Partial and full reflection at structures, e.g., harbour walls and breakwaters
• Wave enforcement at seaward boundaries (time series, spectra)
• Wave absorption at seaward boundaries
• Conservation of mass and momentum in the numerical model is ensured
• Model formulation independent of vertical reference level

R&D

Research projects with TRITON:

• wave induces forces on moored ships
• moored ship response to wave excitation in harbour design
• waves and currents in the vicinity of near-bed structures
• wave boundary conditions for harbours
• wave breaking
• wave transformations over shallow foreshores
• coupling SWAN-TRITON.

Application in projects and commercial availability

TRITON is presently under development. At present we are working on the validation of TRITON. The status of the software is such that we decide case by case whether an assessment with TRITON is feasible, or if we can offer alternative support. We aim at launching a the commercial version of TRITON in 2012.
 
For application before this date, we would be happy to discuss possibilities to assist you in projects involving TRITON, where the TRITON simulations are performed with our most recent R&D version by our own people.
