HISTORIC “1,000 YEAR FLOOD” IN LOUISIANA AND MISSISSIPPI

March 10-14, 2016

PRELIMINARY REPORTS• PRESIDENT OBAMA DECLARES

LOUISIANA AND MISSISSIPPI AS A DISASTER ZONE

• VERY FEW DEATHS SO FAR, BUT 5,000 OR MORE HOMES AND AN OIL FIELD UNDER WATER

• THOUSANDS EVACUATED; THOU-SANDS NEEDINIG TO BE RESCUED

LEARNING FROM GLOBAL DISASTER LABORATORIES

FLOODS

FLOODING

• Flooding occurs somewhere in the world approximately 10,000 times every year 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; in storm surges, and in tsunami wave run up.

FLOODING CAN TRIGGER LARGE LANDSLIDES,

CAUSES OF RISK

FLOOD DISASTER LABORATORIES

“FLOOD LABORATORY”:SALT LAKE CITY, UTAH; 1983

• Unusual flood waters from the annual Spring runoff were diverted down Main Street

MIDWEST USA FLOOD LABORATORY: JUNE-AUGUST 1993

• THE MISSISSIPPI RIVER BASIN COVERS 1.25 MILLION SQUARE MILES

• IT COLLECTS WATER FROM 40 PERCENT OF THE UNITED STATES

SOCIOECONOMIC IMPACTS: GREAT FLOOD OF 1993

The Great Flood of 1993 was the most costly and devas-tating flood in modern history in the United States.

CEDAR RAPIDS, IOWA FLOOD LABORATORY: JUNE 13, 2008

INUNDATION

INUNDATION: ST LOUIS, MO; JUNE 20, 2008

.

• Inundated towns, cities, homes, schools, businesses, and farms,• lost crops and long-term loss of productivity of farm land,• loss of function of roads and bridges

SOCIOECONOMIC IMPACTS

SOCIOECONOMIC IMPACTS (continued)

• loss of function of bridges and utility systems

• Thirty-eight thousand evacuees• Regional business interruption• loss of tourism

SOCIOECONOMIC IMPACTS (continued)

• long-term clean-up (removal of debris, sewage, garbage, and 10-million sandbags)

• Drying out of houses and businesses and their contents,

• Rebuilding of houses and levees.

SOCIOECONOMIC IMPACTS (continued)

• Disposal of damaged home systems (e.g., refrigerators),

• Restoration of water quality in wells and municipal water systems

• Restoration of functions of schools and universities.

•

SOCIOECONOMIC IMPACTS (continued)

• Restoration of millions of acres of prime farm land.

• Rebuilding of cities such as Cedar Rapids, Iowa (estimates reach at least $1 billion).

•

• After weeks of flooding in Iowa, Illinois, Missouri, Indiana and Wisconsin, the region faced billions of dollars in losses and a long recovery period.

FLOODING IN SOUTHERN CHINA

Runoff after several weeks of rain pushed the Xijiang and Beijiang Rivers over their banks in southern China, displacing more than 1.27 million people.

FLOODING: GUIZHOU PROVINCE; MAY 27

FUJIAN RIVER: JUNE 6

FLOODING: GUANGDONG PROVINCE; JUNE 15

SOCIOECONOMIC IMPACTS

The impacts: 57 dead, tens of thousands of collapsed homes, damaged crops across more than 2.12 million acres, and $1.5 billion or more in economic losses.

NORTH DAKOTA, SOUTH DAKOTA, AND MINNESOTA

FLOOD LABORATORY

MARCH - APRIL 2009

REASONS FOR FLOODING:

The flooding was triggered by: 1) A long, snowy and icy winter, followed by 2) An earlier than normal, rapid Spring melt and runoff.

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 levels of morbidity and mortality) is vital for survival.

LESSON: ENGINEERED INFRASTRUCTURE SAVE LIVES

• Infrastructure engineered to withstand the risks from floods (e.g., 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

ALONG COASTAL AREAS IS EXTENSIVE; THE ASSOCIATED
