The year of 1914 had been a difficult one for the British Expeditionary Force, the war that had started in August had not been over by the expected time of Christmas. Additionally many of its original members had become casualties and replacements were difficult to find. 1915 did not go much better, the BEF was still a minor player with only a relatively small number of divisions compared to the many in the French Army. The culmination of several attacks by the BEF in 1915 was the attack in the Loos sector in September where in a mining area north of Arras, the largest British offensive of the war thus far took place. Forced into an offensive in an area which as one senior commander put it was on 'most unfavorable ground', the BEF suffered heavy casualties and little material gain. Probably for these reasons the 1915 battles have been largely ignored and there has been a dearth of decent publications on Loos. Helion and Co Ltd are therefore pleased to announce the publication of a major new work Most Unfavourable Ground. The Battle of Loos 1915 by Niall Cherry. Most Unfavourable Ground offers a detailed look at the planning, execution and aftermath of the fighting. As well as using official records and reports, numerous personal stories have been woven into the account. The author's grandfather was present at Loos as a Chemical Corporal with the Royal Engineers gas units and this major new work reflects the author's passion for the subject. Key sales points: A major new work on an oft-neglected and overlooked offensive launched by the British forces in 1915, Draws on a large number of personal accounts in addition to official sources to provide a rich and detailed account, Includes much information about overlooked aspects of the Battle, including the British use of gas, and medical facilities, Features a large number of rare photographs, a comprehensive selection of maps and an extensive number of statistical tables.

Geotechnical Risk and Safety V contains contributions presented at the 5th International Symposium on Geotechnical Safety and Risk (5th ISGSR, Rotterdam, 13-16 October 2015) which was organized under the auspices of the Geotechnical Safety Network (GEOSNet) and the following technical committees of the of the International Society of Soil Mechanics and Geotechnical Engineering (ISSGME): • TC304 Engineering Practice of Risk Assessment & Management • TC205 Safety and Serviceability in Geotechnical Design • TC212 Deep Foundations • TC302 Forensic Geotechnical Engineering Geotechnical Risk and Safety V covers seven themes: 1. Geotechnical Risk Management and Risk Communication 2. Variability in Ground Conditions and Site Investigation 3. Reliability and Risk Analysis of Geotechnical Structures 4. Limit-state design in Geotechnical Engineering 5. Assessment and Management of Natural Hazards 6. Contractual and Legal Issues of Foundation and (Under)Ground Works 7. Case Studies, Monitoring and Observational Method The 5th ISGSR is the continuation of a series of symposiums and workshops on geotechnical risk and reliability, starting with LSD2000 (Melbourne, Australia), IWS2002 (Tokyo and Kamakura, Japan), LSD2003 (Cambridge, USA), Georisk2004 (Bangalore, India), Taipei2006 (Taipei, Taiwan), the 1st ISGSR (Shanghai, China, 2007), the 2nd ISGSR (Gifu, Japan, 2009), the 3rd ISGSR (Munich, Germany, 2011) and the 4th ISGSR (Hong Kong, 2013).

Craig’s Soil Mechanics continues to evolve and remain the definitive text for civil engineering students worldwide. It covers fundamental soil mechanics and its application in applied geotechnical engineering from A to Z and at the right depth for an undergraduate civil engineer, with sufficient extension material for supporting MSc level courses, and with practical examples and digital tools to make it a useful reference work for practising engineers. This new edition now includes: Restructured chapters on foundations and earthworks, the latter including new material on working platforms and collapse of underground cavities (sinkhole formation). New mobilised-stress-based deformation methods that can straightforwardly be used with both linear and non-linear soil stiffness models and field measurements of shear wave velocity, for serviceability limit state design. Extended sets of correlations for making sensible first estimates of soil parameters, adding deformation-based parameters for broader coverage than the Eighth Edition. Extended section on robust statistical selection of characteristic soil parameters. Greater use of consolidation theory throughout in determining whether actions, processes and laboratory/in-situ tests are drained or undrained. Extended chapter on in-situ testing, adding the Flat Dilatometer Test (DMT), and interpretation of consolidation parameters from CPTU and DMT testing. An updated section on pile load testing. Additional worked examples and end-of-chapter problems covering new material, with fully worked solutions for lecturers. The electronic resources on the book’s companion website are developed further, with the addition of two new spreadsheet numerical analysis tools and improvement of existing tools from the Eighth Edition. Using these, readers can take real soil test data, interpret its mechanical properties and apply these to a range of common geotechnical design problems at ultimate and serviceability limiting states.
