Modern earthworks, 12 May, ICE London. BGA meeting divided into three talks.
Alan Phear from Arup will discuss new railway earthworks for high speed railways - with particular reference to the Channel Tunnel Rail Link. He has been involved in the design and construction of earthworks for the 109km long twin track railway for seven years.
Jack Meldrum from Mott MacDonald looks at dam earthworks. The principal difference between earthworks for dams, compared to other structures, is water.There is the need for the structure both to retain water and for it to sustain exposure to water, both externally and internally.
He outlines the hazards involved.
John Ferguson from Balfour Beatty will discuss sustainable earthwork construction. He will look at how environmental legislation has had the greatest effect on modern earthworks, coupled with changes to modern design and build contracts and early contractor involvement.

The company is run by Angus Miller who started the firm in 1998, and since then has been exploring the 'Earth's story' through guided walks, short courses and lectures.
Miller completed a PhD at Durham University, studying earthquakes at the Hengill volcano in Iceland. This led to work with the British Geological Survey, where he spent two years at the Montserrat Volcano Observatory monitoring the eruption at the Soufriere Hills volcano.
One of the day trips goes up Arthur's Seat in Edinburgh. Walkers can explore the old sandstone quarry, layers of ash and lava, and the remains of the volcanic vent, while taking in views of the Scottish capital.
Alternatively, in June visitors might want to experience the north west Highlands for a week which takes in some of Scotland's finest geology. For prices and booking details visit www. geowalks. co. uk + choice of pictures, see below. Credit:

The 17th century, star-shaped fortress is Europe's largest peat moor and was constructed during the Eighty Years' War. Satellite is being considered as a decision-support tool for mapping, monitoring and measuring changes to the delicate ecosystem surrounding the fortress.
