Group 3 84 Knowing that the weather system and world is far more complex it cannot be explained 100% precisely. Regarding vulnerability, Warehouses were more vulnerable that Cathedral and Dora I due to occupation, maintainability and conservation degree. Besides, vacant Warehouses present a greater vulnerability in an emergency. Adapted methodology helped to describe the vulnerability level of each scenario that hypothesized for Warehouse. This documentation of Warehouses should be part of the Recovery Plans for the worst-case scenario that may cause a severe loss of the Cultural Heritage due to flooding caused by heavy rain events as represented in figure 3. It is assumed for the Cathedral the documentation is useful but not as much needed as the flood risk maps do not indicate a risk for flooding, as represented in figure 4. Regarding Dora I, the documentation should be kept as a backup. And Expert Advisory Board is needed (Structural engineers, experts for conservation as the concrete shows some damages caused by deterioration, simulation specialists) in order to conserve the shared cultural heritage site. The preliminary results obtained serve to reflect on the current risks that affect the cultural areas of Trondheim. Next step should include some strategies by keeping the heritage value of each case study in a professional stakeholder collaboration. Stakeholders have to be as holistic as needed i.e., from local, national, and international levels, as well as the users of the city e.g., citizens, employees, commuters.
