“When the Seine overflows” Thursday March 9, 2023 in France 5 (Video)

The Concorde, the Hôtel de Ville, or the Louvre Museum were flooded … A hundred-year flood of the Seine, equal to or greater than that which occurred in 1910, is a very dangerous hypothesis that could have a very strong effect on Paris and Ile-de-France in Next years. Today, dozens of scientists are working on this great danger, exacerbated by global warming: understanding the mechanism of floods, measuring and predicting their spread with great accuracy, analyzing the role of groundwater, protecting metros or major museums, imagining a city able to withstand …

In the laboratories, researchers study water mechanisms on giant models and develop computer models of floods capable of measuring and predicting their spread. In the sky, IGN’s planes are working on maps that project the extent of flooding to the nearest metre. If over the years Paris strengthens its protection measures, the capital will be more fragile than it was a century ago, with underground infrastructures extending over seven levels. Engineers imagine different scenarios for the design of surface protection that will preserve the overflow networks of the Seine, which flood the metro … or the Louvre. But water can also rise from the basement: geologists are trying to understand how groundwater threatens the bowels of Paris. As for the architects and urban planners, they envision a flexible Paris, capable of letting water flow harmlessly.

Using realistic special effects to tell the story of this horrific flood, this documentary shows what Paris would be like underwater, revealing what researchers and engineers are developing to protect us from. This documentary is also the story of Madeleine, a Parisian who is very attached to her cat…
