Umgiesser Georg

Study of lagoons and other shallow water bodies through the application of numerical models, mainly in the field of hydrodynamics and sediment transport. Development of numerical tools that are especially suited for this task.

Additional interests:

• Numerical forecasts of storm surge in the Adriatic Sea and especially the Venice lagoon;
• Sea-lagoon interaction and exchange rates;
• Residence time and transport time scales that characterize lagoons and semi-enclosed water bodies;
• Training of scientists from developing countries in numerical modeling

• Development of a numerical modeling framework specially suited to water bodies of shallow depth like lagoons and the coastal zone
• Guest editor of special issue of Continental Shelf Research on “Inlet Dynamics”, 2009; Referee, journals and proceedings: Journal of Marine Systems, Continental Shelf Research, Estuarine, Coastal and Shelf Science, Ecological Modelling
• Superivisor of 12 PhD dissertations, supervisor of 11 M.Sc theses.
• University Courses at University of Venice, 2002-2005 (Models in Oceanography) and University of Padua 2003-2005 (Numerical Techniques in Physics and Oceanography)

He wrote more than 100 papers between refereed journals (50 on ISI), refereed books (10), proceedings (60) and other journals.
