Abstract: With the objective of answering marine and coastal engineering needs, sea state databases are created by hindcast simulations over long periods. The wave hindcast ANEMOC-3 database, built using the spectral model TOMAWAC for wave generation and propagation and the hydrodynamic circulation model TELEMAC-2D for tidal water levels and currents calculation, covers a period of 45 years from 1979 to 2023. During the calibration of the database, the numerical results must be consistent with past observational data (in situ or satellite measurements). Among other things, this process relies on calibration to determine “empirical adequacy”. In particular, the calibration aims at simulating a series of reference events by adjusting some uncertain physically-based parameters until the agreement with available data reaches a satisfactory level. The objective of this work is to implement an efficient calibration algorithm, capable of processing measurements optimally, and to estimate the partially known parameters in the numerical model.
