Environmental Dredging of a Chromium Contaminated Fjord
The sediments in Valdemarsviken fjord in Sweden were contaminated with chromium from the discharge of untreated wastewater from tannery operations decades ago. The contaminated sediments were dredged, dewatered, solidified and placed as a engineered fill in a nearshore area.
Long-Term Effects of Maintenance Dredging on Turbidity
Maintenance dredging is required in many estuaries worldwide to provide access to ports and inland waterways. A newly developed dredging module is able to capture the two fundamental processes necessary to model the long-term impacts of dredging on turbidity.

Building with Nature: Sustainable Protection of Mangrove Coasts
Building with Nature is an innovative approach that combines natural processes with innovative engineering methods to realise sustainable projects. Permeable dams are being utilised as part of a Building with Nature solution to help restore the eroding mangrove-mud coast of the Demak district in central Java, Indonesia.
Dredging Sound Levels, Numerical Modelling and Environmental Impact Assessment (EIA)
Underwater sound from anthropogenic sources and its potential adverse effects on the marine environment is a topic of much global interest. This article gives an overview of known sound source levels for various dredging equipment and activities and describes a method used to extrapolate source levels.
