Hydraulic structures are and will be a vital part of the infrastructure for human beings as they provide safe irrigation and water supply, protection against natural hazards, energy generation, and many other highly needed services. Given the current global challenges including water scarcity, abundance in the form of floods, need for clean and affordable energy and environmental issues related to watercourses as biodiversity hotspots, hydraulic structures will remain very relevant in the future. This symposium aims to bring together experts working in the specialized field of hydraulic structures design from fundamental and applied research and practice. It will provide a forum for presentation and discussion of recent advances in knowledge as well as future needs.
