Recent updates to the BGS websites.
The Geohazard notes provide information on how and why the hazard occurs, how it is measured, locations susceptible to the hazard and possible worst case scenarios.
The notes also give details on how the BGS and collaborating organisations respond to such hazards.
Groundwater levels in some regions of the UK are currently at record highs. This has resulted in ongoing groundwater flooding, particularly in the south and south-west of the UK.
This flooding is located on the Chalk outcrop and also on the floodplain gravels associated with the region’s major rivers.
Although groundwater levels, and the incidences of groundwater flooding, will decrease in the floodplain gravels once the rivers return to more normal flows, due to the nature of groundwater movement in the Chalk aquifer, groundwater flooding may persist in some areas for weeks or months ahead.
The winter of 2013&ndash 14 has seen record rainfall in the UK. December rainfall was 154 per cent of the average for the month across the country. This was followed by the wettest January on record for Southern England.
Infiltration of December rain filled up much of the available storage in the ground (soil, gravels, rocks) in many areas. Much of the subsequent rainfall therefore had nowhere to go except to run off the land, moving quickly to rivers and resulting in widespread fluvial flooding.

This whole area is underlain by chalk bedrock belonging to the Seaford Chalk Formation.
There are two possible causes of the hole: natural dissolution of the chalk or chalk mining. In some situations the two interact.
There is some evidence of local mining in this area and sinkholes are also common.More about the geology of the Sinkhole in the middle of the M2
Staff of the Natural History Museum, the Geological Society, and the British Geological Survey were all involved with Piltdown - from discovery to unmasking. Some have been implicated in the forgery itself.
Archivists at the Natural History Museum, the Geological Society and the British Geological Survey pooled their resources to create a web-based exhibition telling the story of Piltdown Man's discovery.
The Piltdown Timeline reveals the history of the forgery and the identity of individuals that have been accused of complicity or culpability in the affair.

A study involving Dr Jez Everest of BGS Scotland and the University of Dundee, has found evidence that suggests Scotland may have been home to a small glacier within the last 400 years - some 11 000 years less than previously thought.
It had long been understood that Britain s last glaciers melted around 11 500 years ago.
However, the combined BGS and Dundee University team has now established that a glacier was in place in the Cairngorms possibly as recently as the 18th century.

The EMD undertakes research into a variety of areas: the parameterisation of 3D geological models the development of numerical process modelling techniques including groundwater, debris flow, multiphase flow and coupled process modelling uncertainty analysis geostatistics and model and data integration, where we apply integrated models to the analysis of a range of environmental problems.

If the rain eases most rivers will return quite quickly to more normal flows, but in some areas the effect of the wet weather may linger as groundwater flooding.
Groundwater flooding occurs when high rainfall raises water levels in aquifers well above the normal range, to the point where water flows out onto the land surface or into cellars and basements, often causing sewers to back up
Because groundwater flows fairly slowly through the soil and rocks groundwater can continue to rise for weeks, or sometimes months, after a rainfall event.More about recent Groundwater flooding in the UK: January 2014
