  1. NO TIME TO WASTESTATES IN THE MISSISSIPPI RIVER’S PATH TO ITS DELTA REGION HAVE ABOUT 2 WEEKS TO AVERT FLOOD AND HEALTH CARE DISASTERS Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA

  2. THE CRITICAL TIMEWEDNESDAY, MAY 11 THROUGH MONDAY, MAY 23, 2011

  3. MEMPHIS:THE RIVER CRESTED AT NEARLY 48 FT ON MAY 9, 2011

  4. CITIES AND DATES WHERE THE RIVER WILL CREST AND LIKELY FLOOD • HELENA—MAY 12 • GREENSVILLE—MAY 16 • VICKSBURG—MAY 19 • NATCHEZ—BATON ROUGE—MAY 22 • NEW ORLEANS—MAY 23

  5. FLOOD HAZARDS (AKA POTENTIAL DISASTER AGENTS) • SO MUCH WATER DISCHARGED WITHIN A RIVER’S DRAINAGE BASIN THAT IT CAN NOT BE ACCOMMODATED SAFELY WITHIN THE FLOODPLAIN • EROSION AND SCOUR • LANDSLIDES (E.G., MUDFLOWS) • DEBRIS

  6. CAUSES OF RISK LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAIN INUNDATION INTERACTION WITH HAZARDOUS MATERIALS STRUCTURE & CONTENTS DAMAGED BY WATER FLOODS WATER BORNE DISEASES (HEALTH CARE PROBLEMS) CASE HISTORIES EROSION AND MUDFLOWS CONTAMINATION OF GROUND WATER

  7. DAMAGE INJURIES DEATHS LOSS OF FUNCTION HEALTH NEEDS ECONOMIC LOSS UNACCEPTABLE RISK RISK

  8. 1) dozens of flooded towns and cities, 2) inundated homes and businesses, 3) lost crops and productivity of farm land, 4) loss of function of roads, THE NATURE AND EXTENT OF THE MOUNTING LOSSES

  9. THE NATURE AND EXTENT OF THE MOUNTING LOSSES • 5) loss of function (e.g., barges, bridges and utility systems) • 6) losses associated with thousands of evacuees • 7) regional business interruption • 8) loss of tourism

  10. 9)long-term clean-up (removal of debris, sewage, garbage, 10-million sandbags) 10) drying out of houses and businesses and their contents, 11) rebuilding of houses and levees. THE NATURE AND EXTENT OF THE mounting LOSSES

  11. 12) disposal of damaged home systems (e.g., refrigerators), 13) restoration of water quality in wells and municipal water systems 14) resumption of schools and universities. THE NATURE AND EXTENT OF THE LOSSES

  12. 15) restoration of millions of acres of prime farm land. 16) rebuilding of cities such as Memphis (costs could reach in the billions). THE NATURE AND EXTENT OF THE MOUNTING LOSSES

  13. FLOODING IS NOT THE ONLY THREATSO ARE THE GROWING POTENTIAL HEALTH CARE NEEDS

  14. DEBRIS-LADEN WATER; MAY 9TH

  15. THE WATER IS A POTENTIAL HEALTH RISK • The Mississippi River flood water is contaminated by the pesticides, industrial pollutants, and debris acquired along the long trip to the delta, and is now full of snakes and other animals.

  16. TAKING A PAGE FROM LONG EXPERIENCE IN THE NETHERLANDS, …NEW STRATEGIC ACTIONS ARE BEING INTEGRATED WITH CONVENTIONAL STRATEGIES TO REDUCE THE RISK

  17. OBJECTIVE: Give the river more space so that it can flood safely.

  18. EXAMPLE 1 • Make the floodplain wider by moving levees INLAND.

  19. EXAMPLE 2 • Lower the floodplain by EXCAVATION so that it will hold more water safely.

  20. EXAMPLE 3 • Add a NEW channel (i.e., a high-water channel) to reroute overflow water away from the river to temporary storage areas (e.g., manmade lakes).

  21. CONVENTIONAL TECHNOLOGIES AND STRATEGIES FOR FLOOD RISK REDUCTION

  22. REAL TIME WEATHER FORCASTING AND WARNING SYSTEMS MEASURMENT TECHNOLOGIES (E.G., STREAM GAGUES) RISK MODELING (E.G., HAZUS, INSURANCE UNDERWRITING) HISTORICAL DATABASES MAPS: 100-YEAR AND 500-YEAR FLOODS FLOOD DISASTER SCENARIOS DRONE PLANES HAZMAT MANAGEMENT CONVENTIONAL TECHNOLOGIES FOR FLOOD RISK REDUCTION

  23. PURPOSE PREVENTION PROTECTION LAND USE CONTROL STRATEGY WATERSHED MANAGEMENT FLOOD CONTROL (DIKES, LEVEES, AND DAMS) HAZARD MAPS (RISK ZONES) STRATEGIES FOR FLOOD RISK REDUCTION

  24. THREE GORGES DAM, CHINA: FLOOD PREVENTION • THE GREATEST ENGINEERING FEAT IN CHINA SINCE THE GREAT WALL

  25. THREE GORGES DAM: 2309 M LONG, 190 M HIGH, 15 M THICK

  26. FLOOD PREVENTION ON THAMES RIVER: LONDON, ENGLAND

  27. PURPOSE SITE MODIFICATION ALERT/WARNING MONITORING RISK ZONES IMPROVED PREPAREDNESS STRATEGY EMBANKMENTS; SANDBAGS EVACUATION STREAM GAGUES; DRONE PLANES 100-500 YEAR FLOOD MAPS SCENARIOS STRATEGIES FOR FLOOD RISK REDUCTION

  28. SAND BAGS: SITE MODIFICATION IN THE MISSISSIPPI RIVER BASIN • 2.5 MILLION SAND BAGS REDUCED LOSSES IN THE 1992 FLOOD DISASTER.

  29. PURPOSE RISK ZONES IMPROVE PREPAREDNESS ENVVIRONMENTAL PROTECTION (E.G., HAZ MAT) STRATEGY 100 to 500 YEAR FLOOD MAPS DISASTER SCENARIOS OIL SPILL CONTAINMENT AND RECOVERY STRATEGIES FOR FLOOD RISK REDUCTION
