 IVING NATURAL DISASTERS – A paradigm shift in the design of hydraulic in
 frastructures\n\nThe world is changing\, not only its climate! Most recent
  studies agree that the future will experience more frequent and severe ha
 zards\, including natural and man-induced floods\, droughts\, extreme stor
 ms\, dam-break waves and tsunamis. In Switzerland\, a report from the Fede
 ral Council showed that increasing temperatures will be responsible for mo
 re violent and unpredictable storms\, harmful not only to people\, but als
 o to critical infrastructure and energy production. In addition\, a warmer
  climate will favour the melting of mountain glaciers\, generating supplem
 entary resources for the achievement of the Energy Strategy 2050. These wi
 ll be associated with an increasing risk of impulse waves in alpine lakes 
 and dam reservoirs\, with potential damages to both people and the environ
 ment.\n\nSuch catastrophic events can no longer be considered too rare to 
 be relevant and actions must be undertaken to guarantee safety\, mitigate 
 damage and reduce reconstruction costs. In parallel\, today’s race towar
 d a more sustainable exploitation of resources challenges the classical hy
 draulic design\, requiring a paradigm shift toward a multi-hazard approach
  with transdisciplinary nature-based solutions. Thus\, the issue of resili
 ence of water infrastructure is of primordial importance\, and mitigation 
 measures should be promptly identified and implemented. In this context\, 
 this seminar initially focuses on the repercussions of highly unsteady flo
 ws on infrastructure. More specifically\, the effect of structural opening
 s on the hydrodynamic load is addressed both experimentally and numericall
 y. Results showed that a more comprehensive understanding of these phenome
 na and their driving mechanism is essential to develop innovative solution
 s to improve design guidelines. Secondly\, this seminar presents additiona
 l challenges associated with extreme floods\, including air-entrainment\, 
 the effect of driftwood accumulation and associated structural loading. Th
 is reveals that a combination of innovative research\, quality education a
 nd interdisciplinary collaborations is the only approach to successfully o
 vercome the challenges that current and future infrastructures are facing.
