TESTIMONIALS

IVAR DAEMEN
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.”

MARK LEE
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.”

CRAIG VOGT
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.”

Can surface turbidity plume generation near a Trailing Suction Hopper Dredger be predicted?
A surface plume from overflow can stay suspended for long periods and distances, resulting in negative environmental impact through increased turbidity and sedimentation.

Monitoring of settling and consolidation of mud after water injection dredging in the Calandkanaal
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.
Interview: Panama Canal’s deputy administrator Ilya Espino de Marotta
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.
