It is already known for a long time that one of the major discrepancies between computations with Boussinesq-like models and measurements, is due to the inaccurate representation of the linear frequency dispersion in the Boussinesq-like long wave models. A comparison of various models as given in Dingemans (1973) showed already large differences between the frequency dispersion of various models. A comparison with measurements in a flume (Dingemans, 1976) showed that the computed wave profiles were also found in the measurements, but at a different location. This was ascribed to the inaccurate frequency dispersion.
