On parameters estimation in dynamic model of suspended sediments

Dynamics of suspended sediments in the shallow Szczecin Lagoon, located on the border between Germany and Poland, were simulated with a simple box-type model. A direct search optimisation method was used to estimate the model’s parameters. The sensitivity analysis of model parameters indicated that model output is most sensitive to settling velocity. The results point out the importance of prior assessment of parameters values before applying the formal optimisation procedure.
