O článku:
Calibration of parameters of mathematical models is still a tough task in several engineering problems. Many
of the models adopted for the numerical simulations of real phenomena, in fact, are of empirical derivation. Therefore,
they include parameters which have to be calibrated in order to correctly reproduce the physical evidence. Thus, the success
of a numerical model application depends on the quality of the performed calibration, which can be of great complexity,
especially if the number of parameters is higher than one. Calibration is traditionally performed by engineers and
researchers through manual trial-and-error procedures. However, since models themselves are increasingly sophisticated,
it seems more proper to look at more advanced calibration procedures. In this work, in particular, an optimization technique
for a multi-parameter calibration is applied to a two-phase depth-averaged model, already adopted in previous
works to simulate morphodynamic processes, such as, for example, the dike erosion by overtopping.
