Groundwater flooding in England costs £530M, says ESI

摘要

The hidden economic cost of groundwater flooding in England amounts to £530M year, a new study by ESI Consulting has revealed. The company has completed national mapping and developed preliminary economic analysis on the risk of groundwater flooding to property and infrastructure. This, combined with other flood risks has now created the first "Flooding from All Sources" dataset using advanced modelling techniques on a 5m grid. Drawing on available Environment Agency (EA), Ordnance Survey, and British Geological Survey data and the GeoSmart national groundwater flood risk maps, ESI is discussing with Defra how these 'flood risk from all sources' maps may be made available for public use.
