A Comparison of field and laboratory overtopping measurements with empirical, numerical and probabilistic predictions

Two sets of overtopping data gathered in the field are compared with laboratory measurements, the available empirical prediction methods for these structures, a numerical Neural Network prediction tool, and a bespoke probabilistic prediction method developed for one of the field measurement sites. Descriptions of each of these are given so that a sufficient understanding of each data set can be gained. For each of the two structures examined, a total of four data sets are available from each of the different methods. These are examined individually to show how each compare, and show some justification for their use. It is concluded, at least for the two structures investigated, that the available desk methods compare well to the measured data.
