The population of London is around seven million; the infrastructure to support this makes London one of the most intensively investigated areas in the UK, where countless boreholes have been drilled for ground investigation and water supplies.
The Thames Gateway Development Zone consists of a 40-mile stretch of land along the River Thames from central London to the Thames Estuary. It is the focus for the biggest development programme in the UK for over 50 years (200 000 new homes will be built).
Subterranean construction work in the London area continues to reveal the presence of 'anomalous' ground conditions. These occurrences can prove costly if not predicted by initial site surveys.
To address these issues the British Geological Survey has established a trans-disciplinary project that works closely with external collaborators to develop a dynamic geoenvironmental model for the London area, within which these 'anomalies' can be explained.
Traditionally the London Basin has been considered to be 'relatively simple' synclinal basin. However, there is a growing body of evidence from recent site investigations suggesting that the structure of the basin is more complex.
The variability of the Lambeth Group, can give rise to difficult ground conditions for civil engineering works. Scientist at BGS are developing 3D property models to understand the detailed distribution of the Groups component units.
This tool has been developed to assist the planning community in the assessment of the potential risk to ground and surface waters from contaminants mobilised as a consequence of development.
Engineering works carried out in central London have unearthed drift-filled hollow features which exhibit curious characteristics. BGS is undertaking a project to look at the occurrence and genesis of these geological features in central London.
To gain full value from the 3D geological model in the urban environment, attribution of the model with engineering geological and hydrological data is necessary.
Areas where Holocene deposits are showing negligible subsidence at the present time may start to subside again under the weight of future flood water and sediment, or rehydration of sediments under flood water.
SuDS are drainage solutions that provide an alternative to the direct channelling of surface water through networks of pipes and sewers to nearby watercourses. What issues need to be considered? What information can BGS provide?
Humans have had such an impact on the environment that scientists are debating whether we have entered a new geological time Epoch — The Anthropocene.
