💧Discover the Highlights from the Webinar on Application of the Lattice-Boltzmann Method in Hydraulics https://www.iahr.org/index/detail/2501

The latest IAHR Water Monograph Webinar took place on 2 June 2026 with over 300 participants. Moderated by Damien Violeau (Électricité de France) and presented by the monograph’s author Jos Derksen (University of Aberdeen), the webinar focused on the “Application of the Lattice-Boltzmann Method in Hydraulics”.

The lattice-Boltzmann (LB) method is a way of performing simulations of fluid flow and related transport processes. In this webinar, Professor Derksen provided an in-depth explanation of the Lattice-Boltzmann Method, a computational approach that discretises fluid flow into lattice points with discrete velocities and collision operators.

If you missed it, the highlights are now published and the webinar recordings are available to watch on demand.

💧How can cities move from proven water solutions to implementation at scale?

The Madrid Water & Cities Workshop brought together city representatives, utilities, researchers, public institutions and private-sector partners to identify the conditions needed to build more resilient, circular and intelligent urban water systems.

The discussions highlighted four connected priority areas:

• Digital Water & Decision Intelligence
• Climate Adaptation & Extreme Events
• Water Reuse & Circular Cities
• Ageing Infrastructure & Asset Management

A central message emerged: authorities are key to scaling technical solutions. Realising better water outcomes requires technical solutions and knowledge to be supported by effective governance, sustained political commitment and financing, defined responsibilities, long-term planning and adequate institutional capacity.

Madrid opened the dialogue. The next phase will broaden it by engaging more cities, authorities, utilities, companies and researchers on the Road to Bari 2027.
