Ambiental releases UKFloodMap4™

Posted: Monday 8th December 2014

Ambiental Technical Solutions Limited, the global leader in flood modelling and prediction, is releasing its fourth generation UK flood dataset on Monday, November 10th.

Covering 100% of the UK, with a full range of return periods, and incorporating the most up-to-date river flow and rainfall data, UKFloodMap4™ provides the most detailed flood maps currently available for the UK, greatly improving the way insurers assess flood risk at a building level. Responding to a need expressed by insurers, it also includes enhanced approaches for resolving off-floodplain risks.

Built using Flowroute-i™, Ambiental’s world-class flood modelling software, UKFloodMap4™ equips insurers with accurate, detailed and easy-to-understand flood information for all major sources of flooding: river, tidal, and surface water (pluvial), as well as reservoir and groundwater. It includes depth and velocity information at the individual property level, enabling more accurate and competitive technical pricing and loss accumulation estimation.

Dr. Justin Butler, MD of Ambiental, commented: “Flood risk in the UK has been increasing significantly, and recent research suggests this trend is likely to continue. The launch of UKFloodMap4, ahead of next year’s implementation of FloodRE, the new flood re-insurance scheme, is very timely. This new, fully updated dataset, will enable insurers to get a much more complete and accurate view of flood risk in the UK. Flooding cost the country over £1bn last year alone.

Feedback from our clients in the insurance market has shown that existing flood data products often fail to pick up significant volumes of ‘off floodplain’ risks, reducing our clients’ ability to price accurately so we decided to enhance the granularity and comprehensiveness of our UKFloodMap4 to address this need.

There is no single definitive flood risk data source used throughout the UK insurance industry, with individual companies often having different views of this growing risk. However, by deploying this dataset throughout the organisation, as well as to MGAs and brokers in a highly cost-effective manner – either stand-alone or in conjunction with other flood datasets – can greatly improve insurers’ risk selection/ management, understanding, and hence pricing, of uncertainty”.

David Martin, Ambiental’s Technical Director, observes: “Wehave included around30% more riversthan in competing products and have completely re-modelledthe entire UK landmass – involving over 1 Million hydraulic models! We have alsoused the latest and best available ‘LiDAR’ topographical data,together with the most current hydrological and river flow data from the UK’s leading flood research centre – the Centre for Ecology & Hydrology (CEH). We have scaled up our international flood mapping and modelling operations in recent years, enabling us to develop and distribute high-precision flood maps for almost any country in the world.”

In our pre-release testing and validation, UKFloodMap4™ has validated extremely well against recent UK flood events as can be seen from the image below. Here Ambiental’s UKFloodMap4™ flood outline (in blue) shows an excellent correlation to the 7th July 2012 flood event in Yealmpton, Devon (red outline).

UKFloodMap4™ is 100% compatible with 3rd party underwriting platforms (including LexisNexis® and SpatialKey) and GIS set-ups.
