Umgiesser Georg

Studio di lagune ed altri corpi d’acqua di bassa profondità attraverso l’applicazione di modelli numerici, prevalentemente nel campo dell’idrodinamica e del trasporto dei sedimenti. Sviluppo di strumenti numerici specialmente adatti per questo scopo.

Altri interessi:

• Previsione numerica di acqua alta nel mare Adriatico e nella laguna di Venezia;
• Interazione laguna-mare e quantità di scambio;
• Tempi di residenza e scale di trasporto che caratterizzano lagune ed altri bacini semi-chiusi;
• Training di scienziati da paesi in via di sviluppo nel campo della modellistica numerica

• Sviluppo di una suite di modelli numerici specialmente addatti per corpi d’acqua poco profondi come lagune o la zona costiera
