FLOODS PART II. THE GLOBAL DISASTER LABORATORY MODEL. AN

INTEGRATED FRAMEWORK FOR GLOBAL DISASTER RESILIENCE

FLOODING

• Flooding occurs somewhere in the world approximately 10,000 times every day as the consequences of a locale having more water than the local water cycle can process within its physical limits.

FLOODS

• Floods occur as the result of: extreme levels of precipitation in thunderstorms, tropical storms, typhoons, hurricanes, and cyclones; after a storm surge, and after tsunami wave run up.

ONE OF WORLD’S FLOOD MOST NOTABLE DISASTER

LABORATORIES: THE YANGTZE RIVER DRAINAGE

BASIN, CHINA

PAST 2,100 YEARS

FLOODING: YANGTZE RIVER

• Historical records indicate that in 2,100 years, between the early Han Dynasty and late Qing Dynasty, the Yangzte flooded 214 times, an average of once every 10 years.

YANGTZE RIVER

CHINA’S FLOOD LABOR-ATORY: THE YANGTZE RIVER

• The Yangtze River, with over 700 tributaries, is the longest river in Asia and the third longest in the World.

• Its headwaters are situated at an elevation of 16,000 feet in the Kunlun Mountains, and its mouth is 3,720 miles away in the East China Sea, north of Shanghai.

HURRICANE DEAN: A CATEGORY 2-3 STORM ON AUGUST 17

• The eye of hurricane Dean, the first of the North Atlantic season, passed between the Caribbean islands: St. Lucia and Martinique, on Friday, August 17.

• The two islands, less than 80 km (50 mi) apart were, were struck with storm surge, heavy rain, and winds of 165 - 200 km per hour (100 - 125 mi per hour).

IMPACTS ON MARTINIQUE

• In Martinique, Hurricane Dean flooded many locales and ripped roofs from houses and buildings.

• 100 percent of Martinique’s banana crop and 70 percent of the sugar cane crop were destroyed.

• Trees were downed.• Electrical power was knocked out.• Airport were closed.• Tourists in coastal hotels were evacuated. • $270 million damage to infrastructure

• After a torrential rain storm on Sunday in southern California’s San Bernardino Mountains, flash floods triggered thick debris flows

• The 5 m (15 ft) debris flows cut off access to two towns: Oak Glen, and Forest Falls.

AMERICAN SAMOA TSUNAMI: SEPT 29

The M7.7 earthquake generated a near-source tsunami with 3 m (10 ft) waves that struck within 5 minutes

after the quake---so quickly that the regional tsunami warning system

that was improved after the December 26, 2004 tsunami disaster, was ineffective..

LESSON: THE KNOWLEDGE AND TIMING OF ANTICIPATORY ACTIONS IS VITAL

• The people who know: 1) what to expect (e.g., inundation from extreme precipitation, storm surge, tsunami wave run up), 2) where and when impacts will happen, and 3) what they should (and should not) do to prepare for them will survive.

LESSON: TIMELY, REALISTIC DISASTER SCENARIOS SAVE LIVES

• The people who have timely, realistic, advance information that facilitates reduction of vulnerabilities, and hence the risks associated with floods will survive.

LESSON: EMERGENCY RESPONSE SAVES LIVES

• The timing of emergency response operations, especially the search and rescue operations that are limited to “the golden 48 hours,” will increase the likelihood of survival.

LESSON: EMERGENCY MEDICAL PREPAREDNESS SAVES LIVES

• The local community’s capacity for emergency health care (i.e., coping with damaged hospitals and medical facilities, lack of clean drinking water, food, and medicine to treat water borne diseases, and high mor-bidity/mortality is vital for survival.

LESSON: ENGINEERED INFRASTRUCTURE SAVE LIVES

• Infrastructure engineered to withstand the risks from floods (e.g., inundation, foundation scour, damage, failure, and loss of function), is vital for survival.

WE CONTINUE TO OPERATE WITH A FLAWED PREMISE:

KNOWLEDGE FROM FLOOD DISASTERS, WHICH OCCUR EVERY

DAY SOMEWHERE IN THE WORLD IN ASSOCIATION WITH RAIN, SEVERE

WINDSTORMS, AND TSUNAMIS, IS ENOUGH TO MAKE ANY NATION

ADOPT AND IMPLEMENT POLICIES TO FACILITATE DISASTER RESILIENCE

FACT: GLOBAL CONSTRUCTION IN THE FLOOD PLAIN OF RIVERS AND
