IAEG 2026 Course #5: Multi-Hazard Modelling, from Theory to Tools

This course, endorsed by the European Federation of Geologists (EFG), will be organised as part of the 2026 Congress of the International Association for Engineering Geology and the Environment (IAEG 2026). The IAEG 2026 will take place in Delft (The Netherlands​​​​​​​​​​​​​​​​​​) from 30 October to 6 November 2026.

The listed IAEG workshops on the EFG calendar are scheduled, but additional workshops may be added and/or the existing ones may be slightly modified.

Dr Irene Manzella, Head of the Centre for Disaster Resilience and Associate Professor in Geotechnical Engineering for natural hazard risk management, Faculty of Geo-Information Science and Earth Observation (ITC), University of Twente, Enschede, The Netherlands

Dr Olga Mavrouli, Assistant Professor, Dept. of Civil Engineering, University of West Attica, Greece.

OVERVIEW:

Understanding and managing complex natural hazards requires robust theoretical frameworks and practical tools that can simulate the dynamics and interactions of multiple hazard types. This workshop offers participants an integrated view of advanced modelling approaches for multi-hazard scenarios, with a focus on practical applications for risk assessment and planning.

TARGET AUDIENCE:

Engineering geologists, geological engineers, civil engineers, and geotechnical professionals.

LEARNING OBJECTIVES:

The workshop will begin with Prof. Shiva Pudasaini, who will present the theoretical foundations of three-phase flow modelling, a powerful framework that underpins the simulation of complex mass flows such as debris flows, rockfalls, and tsunamis. This theoretical insight lays the groundwork for understanding how physical processes are represented and coupled in multi-hazard models.

Building on this foundation, the workshop will feature demonstrations of software tools designed for hazard simulation and rapid scenario analysis. These include:

• Debris flow, tsunami, and rockfall modelling tools, showcasing how theoretical models are translated into operational simulations.
• FastHazard tools, presented by Bastian van den Bout, including FastFlood and FastSlide—user-friendly, rapid modelling tools designed for efficient assessment of flood and landslide hazards in multi-hazard environments.

EXPECTED OUTCOMES:

Participants will gain a comprehensive understanding of both the scientific principles and practical capabilities of modern multi-hazard modelling, bridging the gap between research and real-world application.

TEACHING STYLE:

Lectures, demos, hands-on exercises.

EQUIPMENT REQUIRED:

Laptop with charging cable.
