Dear Colleagues and Friends of IAEG,

It is a great pleasure to host the IAEG 2026 Congress in Delft, the Netherlands, in the first half of November 2026. The congress themed Engineering Geology in a Rapidly Changing World will focus on cutting-edge research on the fundamentals of engineering geology, showcase best practices in the domain and demonstrate the pivotal role of engineering geology in a world struggling with unprecedented challenges.

We will cover a comprehensive set of engineering geology topics, with two over-arching themes: sustainable global development and mitigation of and adaptation to climate change. The congress will be held at the Aula of Delft University of Technology in the Netherlands.

We are looking forward to your participation in IAEG 2026 and to the collective efforts that will shape the future of engineering geology.
