Cascading continental-scale floods across Europe in 1342–1343 - Nature
Tracing cascading continental-scale medieval megafloods across Europe indicates that current flood management is unprepared for such sequences, highlighting the urgent need for proactive flood risk management strategies that account for unusual series of extreme flood events.
