To kick off the conference, Professor Ziegler addressed the different forms of action of water in the soil in his lecture entitled "When the soil starts to swim - considerations on hydraulic failure". In his entertaining lecture, he dealt with the topics of shrinkage and swelling, uplift, erosion and soil liquefaction as well as hydraulic heave.
