The webinar focused on the use of 3Di software for Integral Urban Modeling, particularly in hydrodynamic simulations relevant to urban planning and water management. Hosted by Jonas van Schrojenstein Lantman and featuring Rob van Zee, the session included an introduction to 3Di's capabilities and a demonstration on building urban models. Key applications discussed included flood risk management, drainage design, and climate adaptation strategies, with specific case studies from the Netherlands highlighting holistic approaches to urban water systems. The session emphasized the importance of considering entire urban areas, including rural inflows, to accurately model water flow and manage climate resilience.
