EFFECTIVE INTEGRATION OF EO DATA AND FLOOD MODELING FOR RAPID DISASTER RESPONSE: THE TEXAS 2015 CASE SEVERE STORMS IN TEXAS AT THE END OF MAY CAUSED DISASTROUS FLOOD EVENTS IN MULTIPLE LOCATIONS COSTING TENS OF LIVES AND INFRASTRUCTURE DAMAGES ARE ALREADY ESTIMATED AT AROUND $30M. THIS HIGH-IMPACT EVENT TRIGGERED A ONE-OF-A-KIND RAPID RESPONSE FROM SPACE AGENCIES AND DATA PROVIDERS RESULTING IN A MULTITUDE OF HIGH-RESOLUTION EO SATELLITE IMAGERY, INCLUDING DATA FROM EO-1 ALI, NASA S NRT MODIS, LANDSAT, ESA'S SENTINEL-1 AND ASI S COSMO-SKYMED. IN TOTAL, MORE THAN 60 SATELLITE IMAGES OF FLOODING AT VARIOUS RESOLUTIONS AND TIME INTERVALS HAVE BEEN PROCESSED TO SHOW THE IMPACT OF FLOODING AND HAVE BEEN MADE FREELY AVAILABLE TO THE STATE OF TEXAS TO ASSIST RAPID DISASTER RESPONSE. IN THIS PROJECT, WE PROPOSE TO MAKE USE OF THIS UNIQUE OPPORTUNITY AND USE ALL THE AVAILABLE FLOOD IMAGERY ALONG WITH A HIGH-RESOLUTION FLOOD MODEL SIMULATIONS OF THE EVENTS. SPECIFICALLY, WE WILL FOCUS ON THE CITIES OF HOUSTON AND DALLAS, AND THE TOWN OF CUERO. THE MAJORITY OF THE TIME SPENT ON THIS PROJECT WILL BE TOWARDS COMPLETING TWO MAIN OBJECTIVES: (1) BUILD A HIGH-RESOLUTION TWO-DIMENSIONAL HYDRODYNAMIC MODEL THAT WILL SIMULATE THE BEST INUNDATION RE-ANALYSIS OF THE FLOOD EVENTS IN LOCATIONS (INCLUDING URBAN SETTINGS) WHERE LIDAR FLOODPLAIN DATA AND GAGED RAINFALL AND RIVER FLOW DATA ARE AVAILABLE; AND (2) INTEGRATE THE MODEL EVENT RE-ANALYSIS AND THE SATELLITE FLOOD DATA TO DEMONSTRATE THE UNIQUENESS OF THESE AVAILABLE MULTI-TEMPORAL AND MULTI-RESOLUTION IMAGERY IN COMBINATION WITH THE MODEL. TO DATE, THERE ARE NO DATA AND MODELS TO SUCH A LEVEL OF ABUNDANCE FOR ANOTHER FLOOD EVENT THAT COULD BE STUDIED INSTEAD. THIS IS INDEED A NOVEL AND UNIQUE OPPORTUNITY AND WE SHOULD TAKE ADVANTAGE OF THE STILL ONGOING FLOOD DISASTER TO DEMONSTRATE THE FULL POTENTIAL OF SUCH DATA FOR LOCAL AND STATE DECISION-MAKING AND DISASTER RESPONSE IN A TIMELY MANNER. THERE IS NO DOUBT THAT THE SUCCESS OF THIS CASE STUDY WILL HIGHLIGHT THE VALUE OF RAPID EO FLOOD IMAGE ACQUISITION, PROCESSING AND DELIVERY AND INTEGRATION WITH DETAILED FLOOD MODELING TO NASAS APPLIED SCIENCE AND DISASTER PROGRAMS. IN ORDER TO WORK ON THIS PROJECT IN A MOST EFFICIENT AND TIMELY MANNER, WE WILL ASK FOR A SMALL AMOUNT OF FUNDING FOR ONE YEAR ONLY FROM THE RAPID RESPONSE PROGRAM IN ORDER TO COMPLETE THE TWO OBJECTIVES LISTED ABOVE. OUR TEAM COMPRISES COLLABORATORS THAT WILL PROVIDE DATA AND EXPERT GUIDANCE IN-KIND. IN ADDITION, WE WILL LEVERAGE ON OUR EXISTING NASA AIST PROJECT (14-AIST14-0074) THAT LOOKS AT GLOBAL FLOOD RISK FROM ADVANCED MODELING AND REMOTE SENSING IN COLLABORATION WITH GOOGLE EARTH ENGINE.
