Launched in 1972 by the IADC, Terra et Aqua is a quarterly publication which aims to disseminate knowledge accrued by global dredging professionals as well as solutions to issues facing the industry.
ABOUT TERRA ET AQUA
Articles investigate and explain the latest innovations relevant to emerging and established professionals immersed in the dredging industry and its related sectors.
RESOURCE TO THE DREDGING COMMUNITY
Supported by the IADC, Terra et Aqua represents IADC's commitment to the highest standards of professional conduct in the dredging industry.
WRITTEN BY EXPERTS
Ground-breaking developments within the dredging industry are discussed by professionals, specialists and researchers engaged in the industry’s activities. With expertise from all over the world, authors are encouraged to submit articles for publication in Terra et Aqua.
Staff Director Engineering and Estimating (Van Oord)
“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.”
HR Wallingford Limited
“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.”
A surface plume from overflow can stay suspended for long periods and distances, resulting in negative environmental impact through increased turbidity and sedimentation. Generation of a surface turbidity plume from the overflow of a Trailing Suction Hopper Dredger is investigated by a process-based, detailed Computational Fluid Dynamics model.
As regular maintenance and relocation of sediment deposits are highly expensive, Port authorities seek more efficient solutions for reducing the costs and CO2 emissions of maintenance dredging. One solution, water injection dredging (WID), is carried out for maintaining the sediment deposits which predominantly consist of clay and silt. WID has been proven to be a cheaper solution by leaving the sediment in place, eliminating substantial costs for relocation of the dredged sediment.
Armed with degrees in both Marine Engineering and Engineering Economics as well as 35 years – and counting – of experience at the Panama Canal Authority, Ilya Espino de Marotta has blasted through the glass ceiling wearing a pink hard hat. Amongst the diverse roles she has under her belt, ranging from Marine Engineer in the shipyard to Vice President for Transit Business, Ilya has notably led the Canal’s expansion as head engineer and now oversees operations from the second highest position at the authority.
Soft mud: field performance related to lab experiments, modelling and analysis of time-dependent processes affecting consolidation
Self-weight consolidation plays a major role in the creation of land using mud, the ripening of mud layers and, also, in the storage of contaminated mud and slurries in ponds.
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.
