One of the main tasks in the design and safety assessment of coastal structures is the prediction of wave overtopping rate. In this work, model tree was used to develop a model for estimation ofwave overtopping rate at rubble-mound breakwaters. The main advantages of the model trees are that they produce meaningful formulas. The field measurements in the CLASH database were used for building of the model and the conventional governing parameters were used as the inputparameters. The results of the new model were compared with those of previous empirical formulas and artificial neural network model. It was shown that the developed model is more accurate than the previous ones.
