Launched in 1972, Terra et Aqua is a quarterly journal that aims to disseminate knowledge accrued by global dredging professionals as well as solutions to issues facing the industry. This year marks 50 years of the publication and, in place of the spring and summers issues, we’re celebrating with a special anniversary edition in May.

“The Terra et Aqua is one of the few magazines in our field of work that provide truly in depth articles on a variety of subjects, often based on scientific studies, and very relevant for dredging professionals.”

“Real insights, whether it’s technical, policy or people……whether you have 5 minutes or 50 minutes, it’s always worth picking up.”
Ocean & Coastal Environmental Consulting (Craig Vogt Inc)
“The new Terra et Aqua Journal is “spot-on”. The Journal is easy to navigate and continues to bring forth pertinent articles enlightening us of technical details on dredging projects as well as informing us on policy-related areas, such as the recent Journal that presented sustainability principles for marine infrastructure.”
Frank Verhoeven, President of IADC, shares his thoughts on todays’ issues related to the dredging industry and introduces the articles in this issue of Terra et Aqua.
Green solutions in ports, waterways and coastal projects have increasingly become available thanks to many years of research and pioneering efforts in practice. These sustainable and/or nature-based solutions have shown to be good alternatives for classic solutions, but application is far from mainstream yet. One of the major hurdles is the lack of access of private capital to finance these kinds of solutions despite the strong interest of capital markets in green infrastructure opportunities. Identifying the hurdles and paving a way forward to overcome these hurdles could therefore help to increase the uptake of those green solutions.
A fixed and direct transport connection between Scandinavia and Central Europe has been an enduring vision for many decades. This vision is about to be realised with the construction of the Fehmarnbelt Fixed Link, an 18-kilometre-long immersed tunnel between Rødbyhavn in Denmark and Puttgarden in Germany. When it opens in 2029, the tunnel will be the longest immersed tunnel in the world combining a dual railway and motorway connection. This article provides insight into the improved dredging equipment used and the methodology specially adapted and further developed to the project’s requirements.
Marine dredged sand and gravel make an important contribution to regional supplies of building materials used in England. Marine aggregate dredging however, is known to result in effects to the receiving environment which, if not properly controlled, could cause adverse impacts to a wide range of receptors. As the marine area around England gets busier, competition for space comes with regulatory challenges and an integrated marine management approach that uses a robust planning system is required. This article discusses the regulation of aggregate dredging in England and provides an overview of the sector’s importance in providing primary aggregate.
DEME is very proud that its retractable ladder, specifically designed for hydraulic track excavators, won the prestigious IADC Safety Award 2022, and especially because the design of this invaluable piece of safety equipment is now being shared with other IADC members.
A RICH HISTORY
Published continuously since 1972, Terra et Aqua has benchmarked innovative solutions and provided dredging professionals, engineers and project managers with the most important industry information.
