REDUCING SILTATION IN THE JUIST MARINA - IDENTIFICATION OF SEDIMENT TRANSPORT MECHANISMS BY IN SITU MEASUREMENTS AND NUMERICAL MODELLING

Siltation of the municipal port and marina of the East Frisian island of Juist is investigated by in-situ measurements and hydro-numeric modelling. The combined results can be used to evaluate constructional measures aimed at alleviating siltation effects. Furthermore the collected in-situ measurement data are utilized in the numerical validation process. An alternative port design is evaluated based on results obtained with the hydro-numeric model.
