Unexpected flooding

The impact of extreme weather events

Flooding is traditionally perceived as a river overtopping its banks with devastating consequences for the surrounding urban environment. Recent extreme rainfall in Scotland, Greece and the US have exhibited that surface water flooding can overwhelm subsurface drainage and sewer networks, leading to catastrophic impacts on our communities. 

In this webinar, we discuss how extreme rainfall can affect urban developments and demonstrate how Flood Modeller can be used to quickly and easily assess flood risk caused by potential flash flooding. 

We also show how surcharging drainage systems can be represented to provide an integrated hydraulic model and help assess flood risk more accurately.
