Contaminated Dredged Material: Building Material of the Future? An Investigation into Building Mound
The Dutch Department of Water Management (Rijkswaterstaat) is developing an innovative concept: building mounds (terpen) of dredged material. Terpenor mounds were common in Holland centuries ago: man-made mounds a few metres high that were placed as a protection against the sea.
An innovative environmental clamshell bucket and mobile dredge cell can generate less turbidity than a traditional silt curtain.
Dredging stiff clay is notoriously difficult. A newly patented system using high pressure waterjets in the hopper dredger's draghead has solved several operational problems. For his description of this innovative technique, the author was presented with a 2002 IADC Award at the PIANC Conference in Sydney, Australia.
Large investments in technology and equipment have transformed dredging into an innovative and dynamic industry.
Even during severe storms this innovative dredging system continues its work undisturbed on the seafloor.
An innovative system of collecting tolls has financed the privatisation of maintenance dredging on the River Plate and in the harbour of Buenos Aires.
