NEURO-FUZZY APPROXIMATION FOR PREDICTION OF SIGNIFICANT WAVE HEIGHTS: THE CASE OF FİLYOS REGION

16393

First and the most important phase of designing high cost coastal structures is to forecast the significant wave height (Hs). In this study, an alternative approach to the deterministic and stochastic methods found in literature is proposed. Neuro-fuzzy is a method in which advantages of Artificial Neural Networks (ANN) and Fuzzy Logic (FL) are combined. In the Neuro-Fuzzy models developed in this study, daily significant wave height can be estimated using daily average Hs and significant wave period (Ts) data. Hs and Ts data recorded at different time intervals were used in the proposed models. In this study, Hs and Ts measured in Filyos region of the Black Sea was estimated by the Adaptive Network-based Fuzzy Inference System (ANFIS). Predicted results from proposed models were compared with the measured wave data and it is found that high correlation values are obtained. It is thus concluded that the proposed models can efficiently be used to estimate missing wave data.
