This study presents a probabilistic neural network (PNN) for predicting the stability number of armor blocks of breakwaters. PNN used the experimental data of van der Meer as train and test data. The estimated results of PNN were compared with those of empirical formula and previous artificial neural network (ANN) model. The comparison results showed the efficiency of the proposed method in the prediction of the stability numbers in spite of data incompleteness and incoherence. The proposed method was proved to an effective tool for designers of rubble mound breakwaters to support their decision process and to improve design efficiency. KW - DO - 10.3970/icces.2007.002.035
