Hydrodynamic Models   Hydrodynamic models are used routinely to research and predict a multitude of marine processes such as ecosystem dynamics, oil spill trajectories, storm surge inundation, and ordinary tidal currents. The dynamics of each of these is essentially either two- or three-dimensional in nature. It is always most efficient to use the simplest tool that enables you to solve a problem, so if a 2D model will do the job, then that is what we use.     Over the years we have used many hydrodynamic models. Some we created ourselves, and some we acquired. For processes that can be modelled in 2D - ordinary (“barotropic”) tides, tsunami, cyclones, storm surges, and problems involving wetting and drying (flooding and inundation) - we prefer to use our in-house model, “RUNUP”. RUNUP is based on efficient and modern code developed by Prof. Zygmunt Kowalik of the University of Alaska, author of two highly-regarded books and dozens of scientific publications on the topic. We have extensively tested RUNUP and have full control over all aspects of its operation.     For complex 3D problems, especially those that depend on the thermohaline structure of the water layers, we use the international community model “ROMS”, because it is generally acknowledged to be the best of its type, and because we have found it to be reliable and robust in a wide variety of applications.  No other model of its type receives the level of ongoing improvement and rigorous validation, by so large a number of users worldwide, as ROMS.     We are always happy to discuss your marine-related project. Please send us an email, including your phone number, describing your requirements. You can let our experts provide the solution, or you may decide that with a few tips you can proceed on your own.
