VULNERABILITY ASSESSMENT FOR
FLOODS
![Page 9: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/9.jpg)
WHAT INCREASES VULNERABILITY
MANKIND’S ACTIONS AND NATURAL EVENTS CAN CHANGE THE
VULNERABILITY OF ELEMENTS AT RISK TO FLOODS, A PART OF THE WATER
CYCLE
![Page 10: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/10.jpg)
An element’s vulnerability (fragility) is the result of a community’s actions or
nature’s actions that change some part of the regional water
cycle (e.g., precipitation, storage, runoff, transpiration,
evaporation).
![Page 11: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/11.jpg)
MANKIND’S CONTRIBUTIONAn element’s vulnerability
(fragility) is the result of flaws that enter during the planning,
siting, design, and construction of a community’s buildings and
infrastructure.
![Page 12: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/12.jpg)
MANKIND’S ACTIONS THAT CHANGE SOME PART OF THE WATER CYCLE
• Urban development or industrial development in areas that were formerly wetlands.
• Locating buildings and infrastructure in a river floodplain.
![Page 13: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/13.jpg)
MANKIND’S ACTIONS THAT CHANGE SOME PART OF THE WATER CYCLE
• Actions that increase or decrease river gradients (deforestation, dams, etc).
• Actions that change the runoff pattern or rate (e.g., the city’s concrete footprint)
![Page 14: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/14.jpg)
NATURE’S ACTIONS THAT CHANGE SOME PART OF THE WATER CYCLE
• A flash flood.• Ice jams/ice dams on the river• Rapid melt of snow and ice• Extreme or prolonged
precipitation caused by stalled low-pressure systems.

A RISK ASSESSMENT
• A risk assessment involves the probabilistic integration of:
• The hazard (e.g., floods) and their potential disaster agents (inundation, erosion, etc) that are directly related to the location of the community and what happens in the regional water cycle.
![Page 17: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/17.jpg)
RISK ASSESSMENT (Continued)
• The location of each element of the exposure in relation to the physical demands of the hazard (i.e., inundation, etc.)
![Page 18: SEVERE FLOODING IN THE MIDDLE EAST LEBANON JANUARY 4, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA.](https://reader036.fdocuments.us/reader036/viewer/2022082713/5697bf7a1a28abf838c82aca/html5/thumbnails/18.jpg)
RISK ASSESSMENT (Continued)
• The exposure (e.g., people, and elements of the community’s built environment), represents the potential loss when the natural hazard occurs.

RISK ASSESSMENT (Continued)
• The vulnerability (or fragility) of each element comprising the exposure when subjected to the potential disaster agents.
