Within EXTREMENESS partners from five national research organizations and administration work together:

Helmholtz-Zentrum Geesthacht

The Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht uses models and model data to analyze the interplay between the different factors contributing to storm tides and examines whether or not for selected cases unlikely but physically still plausible combinations of these factors may potentially lead to further hazard amplification.

Deutscher Wetterdienst

The German Weather Service in its branch office in Hamburg analyses the influence of wind fields on storm tides using both, model and observational data. Emphasis here is whether or not there may exist conditions that may lead to further amplification of storm tides but have not been observed so far.

Bundesanstalt für Wasserbau

The Federal Waterways Engineering and Research Institute in its office in Hamburg is engaged with the impact of storm tides in estuaries and in particular analyses the extent to which high river runoff may provide a contribution for further amplification of storm tides in estuaries. Within EXTREMENESS focus will be on the Ems estuary.

Universität Siegen

The Research Institute for Water and Environment at the University of Siegen is engaged in the analysis of potential impacts that exceptionally high storm tides may have in the Ems estuary. For the assessment a hydrodynamical model will be used that will be implemented and validated specifically for the city of Emden.

Universität Hamburg

The Institute of Geography at the University of Hamburg together with regional stakeholders will, for the city of Emden, provide a transdisciplinary reflexive assessment of the most extreme cases. Multiple values and evaluation criteria will be identified, systematized and incorporated into a reflexive evaluation of deduced options that are meant to respond to the potential impacts identified.
