Lessons learned from past floods in Algeria for strengthened disaster preparedness
- 1. LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL FLOODS PREPAREDNESS FOR ALL OF THE LIKELY FLOOD HAZARDS IS ESSENTIAL FOR DISASTER RESILIENCE
- 2. LESSONS LEARNED FROM PAST NOTABLE DISASTERS ALGERIA PART 1: FLOODS
- 3. ALGERIA
- 4. ALGERIA: AFRICA—EURASIA COLLISION
- 5. NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN ALGERIA FLOODS GOAL: PROTECT PEOPLE AND COMMUNITIES WINDSTORMS/DUSTSTORMS EARTHQUAKES HIGH BENEFIT/COST FROM BECOMING DISASTER LANDSLIDES RESILIENT ENVIRONMENTAL CHANGE GLOBAL CLIMATE CHANGE
- 6. Natural Phenomena that Cause Disasters Planet Earth’s atmospheric, hydrospheric, and lithospheric interactions cause FLOODS
- 7. A DISASTER is --- --- the set of failures that overwhelm the capability of a community to respond without external help when three continuums: 1) people, 2) community (i.e., a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g., floods, earthquakes, ...) intersect at a point in space and time.
- 8. Disasters are caused by single- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.
- 9. THE REASONS ARE . . . • The community is UN- PREPARED for what will happen
- 10. THE REASONS ARE . . . • When it does happen, the functions of the community’s buildings and infrastructure are UNPROTECTED with the appropriate codes and standards
- 11. THE REASONS ARE . . . • The community has NO RELIABLE WARNING SYSTEM in place
- 12. THE REASONS ARE . . . • The community LACKS THE CAPACITY TO RESPOND to the full spectrum of emergency situations.
- 13. THE REASONS ARE . . . • The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either this experience or the prior experiences.

- 16. ELEMENTS OF FLOOD RISK HAZARDS EXPOSURE RISK VULNERABILITY LOCATION
- 17. HIGH POTENTIAL LOSS EXPOSURES IN A FLOOD A community’s people, property, essential and critical infrastructure, business enterprise, and government centers can be at high risk.
- 18. CAUSES OF RISK LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAIN INUNDATION INTERACTION WITH HAZARDOUS MATERIALS STRUCTURAL/CONTENTS FLOODS DAMAGE FROM WATER WATER BORNE DISEASES CASE HISTORIES (HEALTH PROBLEMS) EROSION AND MUDFLOWS CONTAMINATION OF GROUND WATER
- 19. WHAT WILL HAPPEN? FLOOD HAZARDS (AKA THE POTENTIAL DISASTER AGENTS)
- 20. FLOOD HAZARDS • TOO MUCH WATER DISCHARGED WITHIN THE DRAINAGE SYSTEM TO BE ACCOMMODATED IN THE REGIONAL WATER CYCLE • INUNDATION • EROSION • SCOUR • MUDFLOWS
- 21. LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL FLOODS PREPAREDNESS FOR ALL OF THE LIKELY FLOOD HAZARDS IS ESSENTIAL FOR DISASTER RESILIENCE
- 22. LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL FLOODS PROHIBITING THE CONSTRUCTION OF BUILDINGS AND LIFELINE SYSTEMS IN THE FLOODPLAIN IS ESSENTIAL FOR DISASTER RESILIENCE
- 23. LESSONS LEARNED ABOUT DISASTER RESILIENCE ALL FLOODS TIMELY EMERGENCY RESPONSE IS ESSENTIAL FOR DISASTER RESILIENCE
- 24. SOME OF ALGERIA’S NOTABLE FLOODS NOVEMBER 10, 2001 OCTOBER 1, 2008
- 25. NOVEMBER 10, 2001 IN A TIME OF POLITICAL CHANGE, DEVASTATING FLOODING FOLLOWED 2 YEARS OF DROUGHT
- 26. ELEMENTS OF THE DISASTER • A month's rain fell in 24 hours, the heaviest recorded rainfall in 20 years, causing devastating floods and leaving over 600 dead.
- 27. ELEMENTS OF THE DISASTER • In Algiers where a wall of water moved down the steep, narrow streets of the slum district of Bab al-Oued,.more than 500 died in the mass of mud, collapsed buildings and mangled vehicles left by the storm.
- 28. October is typically a bad month for heavy rainfall and floods in Algeria
- 29. FLOODING IN GHARDAIA PROVINCE, ALGERIA 700 KM (435 MILES) SOUTH OF ALGIERS OCTOBER 1, 2008
- 30. GHARDAIA, ALGERIA FLOODING; OCT 1, 2008
- 31. IMPACTS AFTER SEVERAL DAYS OF HEAVY RAIN • Thirty dead • Fifty injured • Bridges and roads badly damaged
- 32. THE NEXT FLOOD IS INEVITABLE • BUT, FLOOD DISASTER RESILIENCE IS NOT AN IMPOSSIBLE DREAM!
