3. Dicussed topics
 Assessment and mapping methods of the impact of natural hazards on urban areas (preventive,
postdisaster)
 Visualisation and communication techniques of the assessed impact, including GIS, internet, 3D
 Strategies for the reduction of the impact of natural hazards on urban areas
 Suitable methods of urban design for the mitigation of the effects of disasters in multihazard case
 Partnership models among the involved actors in the decision process for disaster mitigaton
 Urban planning instruments for risk management strategies (ex. master plan)
 Lessons learned from the relationship between hazard, vulnerability and impact in recent events
 Investigation o urban morphology for better estimation of urban vulnerability (interaction between
neighbouring buildings, the influence of the position of a building in the historical centre, ...)
 Investigation of urban morphology to assess postdisaster accesibility of strategical buildings, the
role of the urban pattern for emergency vehicles
 Quantifying models of vulnerability through questionnaires based on point numbers - the role of
statistics
 Interactions between the urban systems which can increase/decrease vulnerability
 The approach difference in the impact on protected urban areas as compared on common urban
areas.
 Keeping the memory in reconstruction/reshape efforts after disasters, the role of heritage habitat.

4. Assessment and mapping methods of the impact of natural
hazards on urban areas (preventive, postdisaster)
 GIS at geography level
 The cost impact of preventive retrofit versus
postdisaster reparation

5. Visualisation and communication techniques of the
assessed impact, including GIS, internet, 3D
 Work in frame of COST TU0801 „Semantic
enrichment of 3D city models for sustainable
urban development“ – Lisbon earthquake
 Questionnaire
 Book available on internet

6. Strategies for the reduction of the impact of natural
hazards on urban areas
 Projects of C.O. Gociman
 Current project: tailoring the intervention
depending on vulnerability and cultural value
 Coursework at the master „Urban design“

7. Suitable methods of urban design for the mitigation of the
effects of disasters in multihazard case
 Projects and coursework of C.O. Gociman
 DESURBS project

8. Partnership models among the involved actors in the
decision process for disaster mitigaton
 Multicriteria decision
 Categories of actors: passive public, affected
people, experts
 Architect, engineer, investor, inhabitant
 DESURBS tools

9. Urban planning instruments for risk management
strategies (ex. master plan)
 Master plan of Istanbul (Balamir)
 Urban system exposure method in RISK UE
project
 Struttura urbana minima / struttura urbana
strategica approaches of the Italian civil
protection
 Tools of DESURBS project

10. Lessons learned from the relationship between hazard,
vulnerability and impact in recent events
 Analysis of L‘Aquila earthquake
 Influences of Modernism
 Participative dimension

11. Investigation o urban morphology for better estimation of
urban vulnerability
 interaction between neighbouring
buildings
 the influence of the position of a building
in the historical centre

12. Investigation of urban morphology to assess postdisaster
accesibility of strategical buildings, the role of the urban
pattern for emergency vehicles
 Studies of the street network
 Space syntax for computer analysis
 DESURBS tools for CityZen
 Studies of the Italian civil protection on
networks
 Agent based design
 GECOMPLEXITY COST action (IS1104)
 DESURBS

13. Quantifying models of vulnerability through questionnaires
based on point numbers - the role of statistics
 The need to convert qualitative data in
quantitative data
 Datascapes
 Geospatial statistics
 GECOMPLEXITY training school

14. Interactions between the urban systems which can
increase/decrease vulnerability
 Examples of successful cooperation between
architect and engineer on building vulnerable
constructions on soft soil (NHESS article)

15. The approach difference in the impact on protected urban
areas as compared on common urban areas.
 Projects C.O. Gociman (see slide before)
 The SFB 461 project dealt with a protected
area but did not consider cultural value

16. Keeping the memory in reconstruction/reshape efforts after
disasters
 the role of “heritage habitat”
 “ruins of the moment”
 Historic incidents database - book

17. A volume will be made
