Published on

Risks associated with floods. Damage to contents, loss of function of buildings and infrastructure, release of hazardous materials, transportation of debris, autos, and houses, environmental dead zones, and disease. Creating turning points for flood disaster resilience. Integration of scientific and technical solutions with political solutions for policies on preparedness, protection, early warning, emergency response, and recovery.

The Floods Of 2013 Remembering Some Of This Year's Lessons From Natural Disasters

  1. 1. FLOODING
  2. 2. REMEMBERING SOME OF THE LESSONS FROM 2013’S DISASTERS PART 3: FLOODS
  3. 3. PHYSICAL EFFECTS OF FLOODS- A PART OF THE NATURAL WATER CYCLE INUNDATION, HIGH-VELOCITY FLOW OF WATER, HIGH-VOLUME DISCHARGE, EROSION, AND SCOUR
  4. 4. A RISK ASSESSMENT LETS DECISIONMAKERS KNOW WHAT WILL LIKELY HAPPEN IN A FLOOD DAMAGE FROM INUNDATION EROSION, SCOUR, AND LANDSLIDES RISK LOSS OF FUNCTION ECONOMIC LOSS
  5. 5. RISKS ASSOCIATED WITH FLOODS DAMAGE TO CONTENTS, LOSS OF FUNCTION OF BUILDINGS AND INFRASTRUCTURE, RELEASE OF HAZARDOUS MATERIALS, TRANSPORTATION OF DEBRIS, AUTOS, AND HOUSES, ENVIRONMENTAL DEAD ZONES, AND DISEASE
  6. 6. CAUSES OF RISK LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAIN INUNDATION INTERACTION WITH HAZARDOUS MATERIALS FLOODS STRUCTURE & CONTENTS: DAMAGE FROM WATER DISASTER LABORATORIES WATER BORNE DISEASES (HEALTH PROBLEMS) EROSION AND MUDFLOWS CONTAMINATION OF GROUND WATER
  7. 7. An element’s vulnerability (fragility) is the result of either a community’s actions and/or nature’s actions that change some part of the regional water cycle (e.g., precipitation, storage, runoff, transpiration, evaporation).
  8. 8. LESSONS FROM THE COMMUNITY Vulnerabilities typically enter during the planning, design, and construction phases of a community’s building and critical infrastructure programs.
  9. 9. LESSONS FROM A COMMUNITY • Urban development or industrial development in areas that were formerly wetlands and locating buildings and infrastructure in a river floodplain will increase the risk (i.e., chance of loss).
  10. 10. LESSONS FROM NATURE • A flash flood, Ice jams/ice dams on the river, and rapid melt of snow and ice and the resultant runoff will usually lead to a flood disaster.
  11. 11. LESSONS FROM NATURE • Extreme or prolonged precipitation caused by a stalled low-pressure system, or after a long, hot, dry season, or after a wildfire will usually exacerbate flooding risks.
  12. 12. A COMMUNITY’S ACTIONS • Actions that increase or decrease river gradients (deforestation, dams, etc.,) and actions that change the runoff pattern or rate (e.g., the city’s concrete footprint) will exacerbate flood risks.
  13. 13. EXAMPLE SEVERE FLOODING IN LEBANON JANUARY 4, 2013
  14. 14. THE THAWING OF A WINTER STORM CAUSED FLOODING THAT CLOSED SCHOOLS THROUGHOUT THE COUNTRY AND LEFT FOUR DEAD
