The 29th Telemac User Conference was held this October in Karlsruhe. Mozaika has participated for a second year on a roll with a presentation of novel approach of adopting hydrodynamic modelling. This year our topic was analysis of modelling one area of the Bulgarian segment on the Danube with data from two different time periods and studying the evolution of the river morphology with the tools provided by Telemac. In addition to the fruitful conversations and new research opportunities discovered, we had a representative at the young scientists meeting.
