CCTV inspections using robot cameras reduces flood risk

New data mapping to monitor blockages and help reduce flooding in the Yorkshire area has been effective, according to the Environment Agency (EA).

The works in Pocklington involve CCTV inspections using robot like cameras to explore a culvert system to help identify blockages. The information gathered by the EA was then used to remove 315 tonnes of gravel, silt and rubble, helping to reduce the risk of flooding in the town.

In 2007, 50 properties in the area flooded after heavy rainfall, causing more than £2m worth of damage.

EA officer Emma Townend said that the work has helped provide a clearer picture of flood risk, and modelling of the town has shown the benefits of the work to reduce flood risk.

She said: "As well as looking at the direct result of our gravel removal work we have used the information to update the flood map for Pocklington on our website.

"We hope this will raise awareness amongst the public, local authorities and emergency services on the areas of land that could be affected by flooding. Over 100 properties are at risk of flooding in the town, so we'd encourage residents to log onto the website."

In addition, a telemetry station has been installed to monitor the level of the beck and a new trash screen fitted to prevent the storm overflow culvert from becoming blocked.

The data will also be used to set up a new flood warning service which provides advanced warnings if there is a risk of flooding.
