NOTABLE HISTORIC FLOODS IN EUROPE Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA
HAZARDS EXPOSURE VULNERABILITY LOCATION ELEMENTS OF RISK RISK
FLOOD HAZARDS (AKA POTENTIAL DISASTER AGENTS) • Too much water inserted too quickly in the regional drainage system to be accommodated normally by physical processes related to the water cycle. • Inundation • Erosion • Scour • Mudflows
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
DAMAGE INJURIES COLLAPSE DEATHS LOSS OF FUNCTION ECONOMIC LOSS UNACCEPTABLE RISK RISK
