Multi-parameter calibration for morphodynamic models

What is it about?

Many of the models adopted for the numerical simulations of real phenomena are of empirical derivation and thus often include several parameters to be calibrated. The success of a numerical model application depends on the quality of the performed calibration, which can be of great complexity if the number of parameters is higher than one. In this work an optimization technique for a multi-parameter calibration is proposed as an alternative to manual trial-and-error procedures and applied here to a two-phase depth-averaged morphodynamic model for the simulation, as an example, of the dike erosion by overtopping.
