Numerical simulation system for the coast of central Chile by coupling numerical models
Using numerical modelling it is possible to anticipate unfavorable wave conditions for port activity. In particular, using coupled numerical models it is possible to include a larger number of variables, parameters, processes and interactions with focus on improving the representation and precision...

Using numerical modelling it is possible to anticipate unfavorable wave conditions for port activity. In particular, using coupled numerical models it is possible to include a larger number of variables, parameters, processes and interactions with focus on improving the representation and precision of processes that occur in the environment.
