In this paper the use of so-called heuristic-free GMDH (Group Method of Data Handling) networks are considered to tune an unknown parameter (the wind stress coefficient) in a model used for prediction of the meteorological effect on the water level of the North Sea. GMDH tries to find unknown relationships between the parameter concerned and other variables, purely on the basis of measurement data (data mining, dependency modeling). The results achieved, i.e. the prediction capabilities of the GMDHbased tuned model, were found to be reasonably comparable with those from the model that had been previously fine-tuned through a years-lasting tuning procedure; moreover, the method which is generally applicable provided more insight into the physics behind the model concerned.
