Ivan Vaní¿ek is Professor in Soil Mechanics and Foundation Engineering at the Czech Technical University in Prague. His research interests are tensile soil characteristics, tensile cracks, application of geosynthetics and environmental geotechnics, all with focus on the design and behaviour of earth structures. Consulting activities: about 500 cases local and abroad. He is chairman of the Czech Geotechnical Society, organizer of 13th European conference on Soil Mechanics and Geotechnical Engineering in Prague 2003, past vice-president of ISSMGE for Europe (2009-2013). Member of the ELGIP platform. He presented invited lectures in more than 40 countries. He is author and co-author of many textbooks, and monographies such as "Earth structures in Transport, Water and Environmental Engineering"; Sustainable construction, Micro-measuring and monitoring system for ageing underground infrastructures. Activities in CEN250/SC7, namely WG 1 - preparation of the second generation of EC 7 Geotechnical design.

Daniel Jirásko is lecturer at the Czech Technical University in Prague; consultant and designer. He has work experience in the UK for 1 year in a consulting company and half a year in Iraq as a supervisor and consultant for several dam projects. His research interests are in environmental geotechnics, earth structures and rock fall. He is a board member of the Czech Geotechnical Society and the Czech & Slovak chapter of ISSMGE, as well as a member of ELGIP (European large geotechnical institutes platform).

Martin Vaní¿ek is technical director, designer, and consultant. His research interests are in calculation models for Earth structures, mainly reinforced by geosynthetics and contaminant transport. He has work experience in Belgium for 1 year in a nuclear research centre and in the United Kingdom for 4 years in a consulting company. He is member of the Czech Geotechnical Society, Czech & Slovak chapter of ISSMGE, author and co-author of many papers and co-author of a monograph on "Earth Structures in Transport, Water and Environmental Engineering". He is a member of a project team preparing part of the second generation of Eurocode 7. On ISSMGE European conferences he had an active role during the last about 15 years.
