NASA FLOOD RESPONSE WORKSHOP FLOODING IS ONE OF THE COSTLIEST NATURAL DISASTERS AND BY 2050 COSTS OF FLOODS IN COASTAL CITIES ALONE ARE PREDICTED TO REACH $1 TRILLION ANNUALLY (HALLEGATE ET AL., 2013). RECENTLY, ALL AROUND THE WORLD, FLOODS HAVE BEEN OF EXCEPTIONALLY HIGH MAGNITUDE WITH RAINFALLS EXCEEDING RECORD AMOUNTS AS WELL AS CAUSING UNPRECEDENTED DAMAGE IN MANY COUNTRIES. RECENT EVENTS HAVE COVERED SPATIAL SCALES WELL BEYOND WHAT WE HAVE SEEN IN THE PAST AND ARE FREQUENTLY SURPASSING TRADITIONAL REGIONAL DISASTER RESPONSE COVERAGE. IN ESSENCE, THESE LARGE SCALE EVENTS HAVE DEMONSTRATED THAT THERE IS A NEED TO ACHIEVE A GLOBAL RESPONSE IN A VERY LIMITED AMOUNT OF TIME, SO THAT RELIEF TEAMS AND DECISION-MAKERS CAN ACT QUICKLY AND AGENCIES AS WELL AS INTERNATIONAL ORGANIZATIONS CAN DEAL SWIFTLY WITH SUCCESSIVE BIG EVENTS AND DELIVER RELEVANT GEOSPATIAL DATA AND FLOOD IMAGERY WHEN AND WHERE NEEDED ALL AROUND THE WORLD. IN THE CASE OF FLOOD MONITORING AND RESPONSE, NASA ALREADY PROVIDES A NUMBER OF SERVICES AS WELL AS IMAGE AND COMPUTER SIMULATION PRODUCTS DURING AN EVENT, EITHER THROUGH ONGOING ACTIVITIES AT NASA CENTERS OR THROUGH NASA PROJECT FUNDING, ALL OF WHICH NEED BE MAINTAINED AND SUSTAINED. IT IS DIFFICULT TO COORDINATE ALL OF THOSE SYSTEMS DURING ONE SINGLE EVENT, LET ALONE MULTIPLE SIMULTANEOUS EVENTS OR SUCCESSIVE LARGE EVENTS. ALSO, EACH OF THOSE SYSTEMS PROVIDES A UNIQUE CAPABILITY AND SO GLOBAL COORDINATION IS NECESSARY AND THERE IS PROBABLY NO NEED TO DEVELOP (YET) ANOTHER SYSTEM BEFORE SUCH A COORDINATION TAKES PLACE. HENCE, THERE IS A NEED FOR A FLOOD RESPONSE WORKSHOP. THIS WORKSHOP WOULD BRING TOGETHER VARIOUS PIS AND LEAD PEOPLE FROM NASAS FLOOD EXPERT POOL TO DISCUSS AND FORMALIZE A GLOBAL FLOOD RESPONSE TO LARGE EVENTS A WORKSHOP PROGRAM COMMITTEE WILL ALSO NEED TO DISCUSS HOW TO BRING IN NEW PARTNERSHIPS WITH THE WATER AND FLOOD COMMUNITIES POSSIBLY INCLUDING THE NATIONAL WATER CENTER, NOAA RIVER FORECAST CENTERS, USACE ON TRANS-BOUNDARY FLOOD AND INSURANCE COMPANIES ON FLOOD RISK, ETC., AND ALSO INVOLVING THE WORLD BANK (ALTHOUGH SCALABILITY OF THEIR SINGLE COUNTRY PARADIGMS WILL BE A SIGNIFICANT CHALLENGE TO ADDRESS). THE PLANNED FLOOD RESPONSE WORKSHOP SHOULD NOT BE A SCIENCE MEETING NOR A RESEARCH REVIEW; RATHER IT SHOULD BE A PRO-ACTIVE DISCUSSION WITH FOLLOW-ON ACTIONS ON HOW TO PROCEED TO BUILD A COORDINATED AND INTEROPERABLE RESPONSE TO FLOOD DISASTERS AND EMERGENCIES.
