This event brings together users of the General Estuarine Transport Model, which was co-developed at the IOW. It is used for a wide range of simulations in the coastal area, from the estuarine scale (e.g. Warnow estuary) to the scale of the entire Baltic Sea or North Sea. At the meeting, users will present their latest projects using this model and identify their problems. Methodological presentations on current developments of the model will also be discussed.
