RPS MetOcean regularly apply a range of sophisticated numerical circulation models to assess the circulation from shelf scale to estuarine applications.
The circulation models are able to provide:-
- 1D, 2D and fully 3D currents
- currents due to tides, winds and atmospehric conditions
- density driven currents
- cyclonic wind/pressure currents.
The range of models include:
- ADCIRC - a finite element shelf scale model which includes cyclonic forcing.
- SHOC - a 3D finite difference model (square grid).
- EFDC - a 3D finite difference curvilinear/sigma coordinate hydrodynamic model.
- 3DD - 3D finite difference suite of models
- Numerical Modelling Brochure (pdf)
