  1. NOTABLE HISTORIC FLOODS IN THE USA Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA

  2. FLOODS

  3. HAZARDS EXPOSURE VULNERABILITY LOCATION ELEMENTS OF RISK RISK

  4. FLOOD HAZARDS (AKA POTENTIAL DISASTER AGENTS) • Too much water inserted quickly in the regional drainage system to be accommodated normally within the water cycle • Erosion • Scour • Mudflows

  5. CAUSES OF RISK LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAIN INUNDATION INTERACTION WITH HAZARDOUS MATERIALS STRUCTURAL/CONTENTS DAMAGE FROM WATER FLOODS WATER BORNE DISEASES (HEALTH PROBLEMS) CASE HISTORIES EROSION AND MUDFLOWS CONTAMINATION OF GROUND WATER

  6. DAMAGE INJURIES COLLAPSE DEATHS LOSS OF FUNCTION ECONOMIC LOSS UNACCEPTABLE RISK RISK

  7. FIVE PILLARS OF RESILIENCE • HAZARDS • INVENTORY • VULNERABILITY • LOCATION • PROTECTION • PEPAREDNESS • EARLY WARNING • EMERGENCY RESPONSE • RECOVERY RISK ASSESSMENT ACCEPTABLE RISK RISK UNACCEPTABLE RISK GOAL: FLOOD DISASTER RESILIENCE DATA BASES AND INFORMATION USA’S COMMUNITIES HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS

  8. SOME OF THE USA’S NOTABLE FLOODS LOW MORTALITY, BUT VERY HIGH ECONOMIC LOSSES
