Engineering Geology and Geomorphology of Glaciated and Periglaciated Terrains

10th November 2018 8:33am by

We attended a fascinating talk last night at the University of Plymouth by Professor Jim Griffiths, the editor of the recent Engineering Geology Special Publication 28: Engineering Geology and Geomorphology of Glaciated and Periglaciated Terrains.

As most of the engineering we do is in the near surface deposits and almost all of the near surface deposits in the UK have been directly or indirectly affected by glacial and/ or periglacial processes, understanding these processes is essential to ensure provide appropriate engineering solutions and avoid potential catastrophes within them.

This publication presents the latest thoughts and best practice when working in former glaciated and periglaciated environments. This will be a very well-read publication in our office!

The photograph shows a glacial erratic rock, estimated to weigh more than 130 tonnes, found 9m below ground after being unearthed during construction excavations in Everett, Washington, USA. This illustrates how important it is to understand the (geomorphological/ glacial) process, to understand the product (ground conditions); if the ground model were not correct and if the process were not understood, it would be easy to misinterpret 2m-3m of coring into this boulder as bedrock!
