EVENT OPEN

A geological hazard (geohazard) is the consequence of an adverse combination of geological processes and ground conditions, sometimes precipitated by anthropogenic activity. The term implies that the event is unexpected and likely to cause significant loss or harm. 

To understand geohazards and mitigate their effects, expertise is required in the key areas of engineering geology, hydrogeology, geotechnical engineering, risk management, communication and planning, supported by appropriate specialist knowledge of subjects such as seismology and volcanology. There is a temptation for geoscientists involved in geohazards to get too focused on the 'science' and lose sight of the purpose of the work, which is to facilitate the effective management and mitigation of the consequences of geohazards within society.

The study and assessment of geohazards into the wider social context, helping the engineering geologist to better communicate the issues concerning geohazards in the UK to the client and the wider public.

Module Overview

Carbonate hazard: mining and dissolution

Carbonate rocks like limestone and chalk present a particular set of engineering geological challenges both to existing development and whenever new development is planned. The advent of national cavity databases assists with the preliminary checks of whether natural or mining cavities are recorded on site or in its vicinity, but it is usually essential to further understand ,in more detail, the site location in its wider geomorphological and historical context to truly assess the engineering risks. Many professional indemnity claims are frequently associated with a lack of due diligence of third party data, leading to incorrect assumptions and advice about sites and, in turn, risking unsafe development.

For natural cavities it is important to appreciate the range of types, depths and scales at which they can occur. The nature of the carbonate terrain and its geological and geomorphological development is important when creating a ground model for the site and using this to design and execute the ground investigation. The investigation needs to characterise the site sufficiently to provide safe engineering solutions. Similarly, knowledge of past regional factors (industries, styles, scales) that have led to the need for underground mining (often poorly or unrecorded and pre-dating published maps) requires appreciation in order to evaluate the potential for past mining at sites and how to develop safe site development strategies. 

The training session will concentrate upon (1) guidance for improved methodology for the assessment of sites underlain by carbonate terrains to check their geohazard potential, given that this appears to be a weakness for many geotechnical investigations, (2) consideration for investigation strategies and (3) review.
