Last summer’s intense heatwave ended with thunderstorms and flash flooding. During summer 2022, intense heatwaves saw much of Europe reach record-breaking temperatures (the UK hit 40°C for the first time). Severe droughts led to dry ground, reservoirs running empty and hosepipe bans, and there was an obvious need for rain to recharge depleted water stocks. However, when the heatwaves finally ended, the UK (and other parts of Europe) were subjected to another form of extreme weather: thunderstorms and flash flooding.
And in May 2023, heavy rain – again following months of drought – led to extensive flooding across north-east Italy. Causing over 20 rivers to burst their banks and triggering hundreds of landslides, the flooding displaced around 40,000 people.
While they’re often localised, periods of intense rainfall can be very costly, especially when a prolonged spell of hot, dry weather precedes them.
Twinn has conducted extensive research into flood modelling. And while modelling is, of course, essential to identifying risk, it’s worth remembering the following:
