Interest in marine renewable energies has grown in recent years, especially in northern
European shelf seas where several technological devices have been developed. In this
context, numerous investigations focused on accurate predictions of tidal currents and their
respective kinetic energy. An empirical estimation of the current velocity is explored in this
study, where three different methods are presented. The first method is a linear
approximation of the tidal vector velocity as a function of the tidal coefficient (ratio of the tidal …
