Resilient Cities | Flooding: Exploring Early Warning Systems | Ep#2 | AXA Research Fund


Current predictions are global average sea level rise will double by 2100.
(GLOBAL SEA LEVEL RISE IS EXPECTED TO DOUBLE BY 2100) But that’s only half of the story, inland cities are equally under threat of extreme weather events. inland cities are equally under threat of extreme weather events.
(INLAND CITIES ARE EQUALLY UNDER THREAT) For example in 2016, flooding in Paris and its region cost more than 1 billion euros. For example in 2016, flooding in Paris and its region cost more than 1 billion euros.
(IN 2016 FLOODING IN PARIS AND ITS REGION COST MORE THAN €1 BILLION) We are experiencing flood claims all over the world. It induces a lot of damage with thousands of people affected.
(DAMAGE TO INFRASTRUCTURE: HOSPITALS, TRANSPORT, SCHOOLS, BUSINESSES, HOMES) Historically many cities have been built either on coasts or rivers, just because they needed to be supplied with goods. It is very important for us to improve our knowledge about floods, to provide better information to our clients, to improve the resilience of cities we are insuring. My AXA Research Fund project is about better forecasting of floods and flooding. We develop models and then those models are the core of early warning systems.
(DEVELOPING MODELS FOR FLOOD EARLY WARNING SYSTEMS) We get the data from the river gauges, based on the river gauges data we calibrate the model and the model will allow us to simulate the flood wave.
(DATA ENABLES SIMULATION AND PREDICTION OF FLOOD WAVES) So we can provide an early warning if we first calibrate the model based on stream flow data and observed data.
(STREAM FLOW DATA. OBSERVED DATA) If you provide warning, the damage from the flood will be as small as possible. If we get your early warning system for people, for cities, for businesses, what do you think are the actions they can take? Cities can build more walls around metro entrances. People can just move all their valuables upstairs. If their car is parked along the river, they can move their car. If I am a farmer and my livestock is on low ground, I can move it. But all that I cannot do it within a few minutes. Early warning systems provide what is the most valuable thing: it provides time.
(UNDERSTANDING FLOODING) it provides time.
(PLANNING FOR GROWTH) it provides time.
