Great Britain’s first national flood map has been launched to understand and plan for future risks

In partnership with flood modelling experts Ambiental Risk Analytics and gas network Wales & West Utilities, we have launched Great Britain’s first national flood map, which incorporates current and future predictive flood scenarios for the 2020s, 2050s and 2080s.

Delivered via a new Climate Change Adaptation Reporting service, it provides asset managers, infrastructure owners, landowners, their advisors and reporting organisations with the ability to understand future flood risks on existing assets and infrastructure, and create a plan to adapt in a phased, responsible and appropriate manner, removing the need to create manual estimations.

The Wales & West Utilities initiative

The Wales & West Utilities initiative developed into a collaborative innovation project with Landmark and Ambiental. Wales & West Utilities are the first utility in the UK to use the data as part of its UK Climate Change Adaptation Risk Assessment, Reporting and Investment requirements, as per the government’s Climate Change Adaptation Reporting guidelines.

The dataset incorporates the latest river flow, rainfall, sea-level rise and climate change predictions available, and allows the creation of unique, innovative new layers, providing insight into flood hazards and the resulting impacts on property, riverbanks, transport networks, and bridges.

Using the service, Wales & West Utilities can assess how flood risk and river erosion is predicted to vary locally and regionally at different time periods and under different emissions scenarios – and the impact that could have on the gas network where pipes may be exposed by the river bed and bank erosion.

This will allow the company which serves 7.5 million people across Wales and the southwest of England, to invest to protect the network earlier and at a lower cost. The programme to develop these mapping layers started during Wales & West Utilities’ response to Defra’s first round of Climate Change Adaptation reporting in 2011.

Oliver Lancaster, future of energy project manager for Wales & West Utilities, said: “Being able to analyse future flood scenarios is hugely beneficial for us, so we can determine the impact of climate change on our gas network and the services we deliver to our customers.”

Dr Justin Butler, CEO of Ambiental, said: “The potential for improved planning, risk mitigation and adaptation as a result of this launch is considerable. Today, hazards resulting from the weather play a fundamental part of many businesses, particularly for utilities companies who face risk to supply and transportation from droughts and floods.

“In a changing climate, however, existing systems and practices may not be adequate and it is important to take action using the intelligence that can be relied upon to make informed decisions.”
