I've worked on my Florence in Flood series since 2012. During that time, I've researched other 'great floods' on mainland Europe. I've recently started to look further into the history of Paris' 1910 flood.
In late January of 1910 the Seine rose eight meters above it's ordinary level, after weeks of heavy rainfall. The waters didn't overflow the river's banks within the city, but flooded Paris through tunnels, sewers, and drains.
