    predictive simulation computerised models
  • -transmit information as far as possible to all
    the actors involved
  • -react in an integrated way with the other levels
    of government (share and adapt responsabilities
    among the different crisis centres in Paris, City
    centre, Police centre, fire department center,

Conclusion
  • Only the occurrence of the centenal overflooding
    will tell us if we are ready, for the 1910
    experience is very far away and cant actually be
    tranposed to the 21st century situation (we are
    no doubt far more vulnerable today because more
    dependant to technology)
  • We also are aware that information will be a key
    to mitigate the crisis
