Whereas fluvial flood risks have, in recent years, become better appreciated and understood, little is generally known about the risks posed by groundwater emergence. To better understand the risks of groundwater flooding, the Department for the Environment, Food and Rural Affairs (Defra) commissioned a scoping study to assess these risks. As part of the scoping study, provisional maps of areas vulnerable to groundwater emergence from consolidated aquifers were produced that reflect the groundwater conditions experienced in the exceptionally wet winter of 2000–2001. These maps, covering all consolidated aquifers of England, are presented as a provisional set of risk maps that, with further refinement, could be utilized in regional planning decisions and for flood risk management.
