#HydrolinkMagazine
Hydrolink is the primary magazine of the IAHR community and one of the highest-rated member benefits. It brings you the latest developments in the field of hydro-environment engineering and research through articles on projects, research, and new methods and tools of interest to the community. It also provides a platform for reporting on IAHR Conferences and news from our members, and offers a forum for exchanging information and spreading the word on topics and projects relevant to the community.
The online version of Hydrolink is open to non-members since 2021 as part of the efforts of the association to disseminate and share knowledge. In addition to the online version, IAHR members will continue to receive their full colour printed copy at their desks periodically as a membership benefit.
ISSN: 1388-3445
Publication Frequency: 4 issues per year.

Digital Transformation is one of the IAHR Thematic Priority Areas of the 2024-2027 Strategic Plan. To fully realise the promise of digitalising the water cycle, action must be taken across all levels. IAHR is committed to advancing digital transformation in the water sector, focusing on five key areas essential for a sustainable, data-driven future. Among these, Digital Twins stand out as a particularly powerful tool to enable more comprehensive and dynamic management of the water cycle.
Digital twins are virtual representations of physical systems or infrastructure facilities connected to their physical counterparts through sensors providing data on their condition and/or performance in real time, which allows optimising the management or the operational performance of these systems. The use of digital replicas of physical systems started in the aerospace and systems engineering fields in the 1960s, but the concept of a digital twin was not introduced until the early 2000s, while the term “digital twin” was coined in 2010.
As digital transformation is one of the priority areas of its strategy, IAHR will continue fostering opportunities for collaboration and knowledge sharing on digital twins, as well as on other key digital accelerators, including remote sensing, advanced modelling, sensors and the Internet of Things, and artificial intelligence and machine learning.
This issue of Hydrolink reflects that commitment, gathering insights and experiences from experts and practitioners around the world on the role and potential of digital twins in advancing water science and engineering.

About the Editor

Angelos Findikakis received his first degree in Civil Engineering in 1968 from the National Technical University of Athens, Greece. After working on water resources planning and development studies in Greece he came to Stanford for graduate studies in 1973. Since 1980 he has been working for Bechtel Corporation in San Francisco. Over the years he worked on a broad range of water studies in support of the permitting, design and construction of several industrial projects including civil infrastructure, power, mining, oil and gas, and waste storage facilities. As a Bechtel Fellow since 1998 he advises senior management on questions related to his expertise, participates in strategic planning, and helps disseminate new technical ideas and findings throughout the organization.
