GeoSmart has joined forces with the Flood Forecasting Centre (FFC) to help provide an exploratory service to develop options for improved advance warning of groundwater flooding to the public and business community. In the trials, GeoSmart analyses hydrometry data to calculate and model rising groundwater levels. While the effects of surface water runoff from flooding into rivers due to heavy rainfall are more immediate and understood, groundwater flooding can occur up to 30 days after a surface flooding event, as the water takes time to percolate and move through the landscape, until it emerges in key risk areas. With nowhere to go, it can rise through floorboards, air bricks and into sewer systems. www.geosmartinfo.co.uk
