This week in our series of ‘Flood for thought’ we’re going to be covering flash flooding. We hope to help you to gain a greater understanding of what flash flooding is, how to avoid it and how to tell if you’re at risk.
‘Speed’ is the key word that comes to mind when I think about flash flooding. Rainfall is heavy, floods happen fast and water levels rise quickly. Devastation can happen in moments.
Flash floods are extremely unpredictable and by far the most dangerous type of flood that can happen. Flash floods occur when excessive water fills a dry creek or river bed or any active creeks and river beds. These floods come with little to no warnings whatsoever and are difficult to deal with, as drains aren’t able to cope with the amount of water. The sheer speed at which the water flows in flash floods is strong enough to move objects like cars, trees and large rocks. NEVER try to drive through a flash flood.
The east coast of England was the most recent area to be affected by flash flooding – residents described roads as ‘like a river’ with 3 foot of standing water in some parts of the area from just one night of rain.
Are you at risk of a flash flood? Densely populated areas are at high risk of flash floods. Buildings, roads, driveways and in general most man made areas increase the amount of runoff because rainwater can’t be absorbed into the ground, which in turn increases the likelihood of flash flooding.
People who live in areas near rivers are highly likely to be victims of flash flooding – Rivers already provide a platform for water to have an immediate impact. The water cannot be absorbed or go anywhere, so any river hit by heavy rainfall will begin to rise rapidly. Levee’s protect embankments and rivers from high water overflowing but are known to fail.
As I’ve mentioned a few times, flooding is very unpredictable and is therefore hard to avoid or prepare for, especially flash flooding. It can happen literally overnight. We always say that flooding is unpredictable and it can happen to anyone, anytime and anywhere.
