VeylonDear members of EWG Dams and Earthquakes,
Dear colleagues,

As Chairman of the European Working Group, I am pleased to invite you to the 7th EWG meeting, which this time takes the form of an international symposium. The three previous symposia, held in Saint-Malo (France), Rome (Italy) and Lisbon (Portugal), were great successes on the scientific, technical and human aspects. They brought the research and engineering communities closer together, and contributed to a better understanding of seismic risk and the emergence of safer seismic design methods and practices. While the work of the EWG has been able to continue in a remote form, this symposium will be the first post-COVID event to bring us together in the true sense of the word.

I would like to express my sincere gratitude to the Greek Committee on Large Dams for agreeing to organize this symposium in this magnificent city of Athens. I would also like to highlight the work of the Scientific Committee, which has developed the symposium program around the following themes:


  •  Earthquake hazard parameters (e.g., ground motion, surface fault movements) for dam safety evaluation
  •  Measurement of seismic and post-seismic response of concrete and embankment/tailings dams
  •  Experimental behavior and modeling of dam materials under cyclic loading
  •  Seismic performance of concrete dams and their impacted area. Case histories, analysis & validation, design
  •  Seismic performance of embankment/tailings dams and their impacted area. Case histories, analysis & validation, design
  •  Earthquake safety evaluation of safety-critical dam elements (e.g. spillways, low-level outlets)

More than ever, hydraulic structures are critical infrastructures for our societies. It is our duty to do our utmost to ensure the safety of our fellow citizens in the face of the threat of natural hazards. This symposium gives us a unique opportunity to bring our community together to share our experience and practices in the field of earthquake engineering applied to dams. I am convinced that this symposium will provide all those present with the opportunity for fruitful scientific and technical discussions that will contribute to the advancement of European dam engineering.

I look forward to seeing many of you in Athens in September 2024.

Please accept my warmest and most sincere greetings.

Guillaume Veylon


DDakoulasear colleagues,

On behalf of the Greek Committee on Large Dams, it is our utmost pleasure to extend a warm invitation to you for the forthcoming International Symposium on Dams and Earthquakes, to be held in Athens, from September 12th to 13th, 2024. The symposium stands as a significant opportunity to convene a diverse array of international experts in dam design and earthquake engineering. Our aim is to foster a dynamic exchange of innovative ideas, experiences, and research findings, all geared towards advancing the seismic safety of dams worldwide.

Located in the heart of Greece, Athens prides on its rich history and culture spanning over 5000 years. From its iconic archaeological sites to its world-renowned museums and vibrant art galleries, Athens offers an unparalleled blend of ancient grandeur and contemporary charm. We are confident that your time here will be enriched by exploring its myriad attractions alongside friends and colleagues.

We trust that the International Symposium will prove to be an intellectually stimulating and rewarding experience, complemented by the enriching backdrop of Athens' cultural tapestry.

We eagerly anticipate your participation and look forward to extending our heartfelt welcome to you in Athens.

Warm regards,

92e Réunion Annuelle de la CIGB et Symposium International sur les "Barrages pour les populations, l'eau, l'environnement et le développement".


New Delhi, Inde

! Nouvelle date ! 27 Sept. - 3 Octobre, 2024



Chers collègues et amis de la CIGB,


Je suis ravi d'adresser, au nom de la Commission Internationale des Grands Barrages (CIGB), une invitation sincère à nos 106 estimés comités nationaux.


C'est avec grand plaisir que nous vous invitons à envoyer des délégués et des personnes accompagnantes à la très attendue 92e Réunion Annuelle de la CIGB, prévue dans la vibrante capitale de l'Inde, New Delhi, du 27 Sept. au 3 Octobre 2024.


New Delhi offre une occasion captivante de s'immerger dans la riche culture, le patrimoine et l'hospitalité chaleureuse du pays. En tant que centre d'idées et d'innovation, la ville constitue le cadre idéal pour cet événement, qui rassemble des experts et des professionnels du monde entier. De plus, le mois d'octobre en Inde offre des conditions météorologiques idéales, ce qui laisse présager une expérience agréable et inoubliable. Le diligent Comité national indien (INCOLD) accueillera la 92e Réunion Annuelle et le symposium international de la CIGB, offrant un programme exceptionnel dans un cadre captivant.


S'appuyant sur les succès des précédents rassemblements organisés par la CIGB, notamment les congrès de 1951 et 1979, ainsi que la réunion annuelle de 1998, nous prévoyons avec enthousiasme une 92e Réunion Annuelle et un Symposium International remarquables et inoubliables pour la CIGB 2024.


Le thème du symposium international CIGB 2024 est "Des barrages pour les gens, l'eau, l'environnement et le développement", soulignant le rôle essentiel des barrages dans le développement durable et la protection de l'environnement. L'événement proposera un large éventail de sessions techniques, de conférences plénières et de débats d'experts, offrant ainsi une excellente plateforme aux participants pour partager leurs expériences, leurs points de vue et leurs meilleures pratiques, tout en favorisant l'apprentissage mutuel.


Parallèlement au programme technique, il y aura de nombreuses possibilités de réseautage et de rencontres, notamment des événements culturels, des visites techniques et des activités sociales, qui vous permettront de vous immerger dans la culture locale et de faire l'expérience de l'hospitalité chaleureuse du pays d'accueil. L'Inde occupe une place de choix en tant que membre de longue date de la CIGB, avec un palmarès impressionnant de plus de 5 264 barrages, dont environ 437 sont actuellement en cours de construction. Le pays est un leader mondial dans le développement d'infrastructures hydrauliques vitales, à l'origine de projets importants tels que les barrages de Bhakhra, Koldam, Tehri, Bichom et Subansiri Lower, ainsi que les projets d'amélioration de la remise en état des barrages soutenus par la Banque mondiale. Ces projets modernes d'infrastructures hydrauliques, soutenus par INCOLD, ont contribué de manière substantielle à la croissance durable des secteurs de l'agriculture, de l'approvisionnement en eau et de l'électricité en Inde, répondant ainsi efficacement aux demandes croissantes d'une nation dynamique.


Avec la plus grande confiance, nous vous assurons que la Réunion Annuelle 2024 sera un succès retentissant. Nous vous encourageons à marquer vos calendriers et à nous rejoindre à New Delhi, en Inde, en octobre 2024. Je me réjouis de votre présence à cet événement prestigieux.





Michel Lino

President de la CIGB
