Annual Meeting 2016: I-STORM marks decade of knowledge sharing! 

Annual 2016 1

Storm Surge Barrier (SSB) professionals from the UK, Italy, USA, Belgium, Holland and Russia were amongst the 150 delegates at I-STORM’s 2016 Annual Meeting at the Eastern Scheldt Barrier in the Netherlands in October. The event provided an opportunity for colleagues to share their knowledge, be inspired and improve the performance of SSBs.



This year’s event marked the 30th anniversary of Eastern Scheldt and a decade of the I-STORM network. Delegates heard about the latest operations and developments at SSBs from around the world, and participated workshops ranging from: Sea Level Rise; Risk Based Asset Management; Peer Review; Knowledge Management and more, each designed to facilitate the sharing of expertise and assist future improvements.


Willy Dekker, Director of Network Management at the Rijkswaterstaat and I-STORM Strategic Board Chair said:  ‘I’m proud that the I-STORM network has grown in professionalism whilst remaining so open and hospitable. I’m confident that we’ve built a solid governance in which Core, Barrier and Associate Members can play their role in sharing their specialist knowledge on operating, managing and maintaining Storm Surge Barriers.


I saw many new initiatives between members, who shared interest and inspiration for further cooperation. I very much encourage this and hope you do whatever is needed to stimulate that kind of cooperation. ‘
