Geotechnical laboratory testing of glacial deposits from Aldbrough, phase 2 boreholes

This report is a published product of an ongoing study by the British Geological Survey (BGS) of
the coastal change at Aldbrough on the Holderness coast, East Riding of Yorkshire, UK. The test
site at Aldbrough has been selected as one of the BGS Landslide Observatories because it is
representative of the high rates of coastal recession along this stretch of the east coast. The
Aldbrough Landslide Observatory is operated under the BGS ‘Slope Dynamics’ task within the
BGS’s ‘Landslide’ project of the ‘Shallow Geohazards and Risk’ team. As well as providing new
insights with respect to the volumetric rates of recession and the near surface processes, it is a
focus for the trialling of new surface and subsurface monitoring technologies. The establishment
of the Aldbrough observatory and the initial research findings are reported in a series of reports in
addition to this report. These are:

Whilst this report is focused on the geotechnical laboratory testing programme, it should be read
in conjunction with the reports listed above, which provide further details on drilling and
instrumentation and on survey and monitoring. A series of reports will follow presenting the
updated survey and monitoring reports, and their publication will be announced through the BGS
project web page. Readers of these reports will probably also be interested in the context for this
research, which can be found in:
