In this work we present a numerical study of the long wave conditions induced in the old Venetian Harbor of Chania (in the island of Crete, Greece) using two models. The fully nonlinear-weakly dispersive COULWAVE code and the weakly nonlinear-weakly dispersive TUCWave code. The two models are used to determine the resonant frequencies, amplitudes and modes of the entire harbor basin. The presented results are compared and discusse
