Mapping water quality with drones: test case in Texel

Winning co-author Liesbeth De Keukelaere the Young Author Award, an article about the pilot test case organised at the Prins Hendrik Zanddijk project in Texel, The Netherlands, demonstrating drone technology for water quality monitoring.

Sustainable management of the beneficial use of sediments: a case studies review

CEDA’s Working Group on Beneficial Use aims to inspire sediment stakeholders and practitioners by describing the importance of sediments in the context of sustainable development and sharing a curated selection of case studies.

New article: The Mud Motor

12 September 2019 - The Mud Motor. A beneficial use of dredged sediment to enhance salt marsh development.  An innovative approach to beneficially re-use dredged sediment to enhance salt marsh development was tested by a ‘Mud Motor’. A Mud Motor is a dredged sediment disposal method in which a semi-continuous source of mud in a shallow tidal channel allows natural processes to disperse sediment to nearby mudfl

Can a preliminary model describe CSD spillage due to centrifugal advection?
Can a preliminary model describe CSD spillage due to centrifugal advection?

Depending on its size and installed power, a Cutter Suction Dredger is capable of cutting a wide range of soil types. Although precise and relatively efficient, a CSD can spill significantly. The authors propose a preliminary model which describes spillage due to centrifugal advection.

Can a lake’s ecology be restored with unwanted sediment?
Can a lake’s ecology be restored with unwanted sediment?

In collaboration with the Natuurmonumenten (the Dutch Society for the Preservation of Nature), Boskalis constructed the Marker Wadden. The archipelago situated within the Markermeer enables processes which revitalise the natural ecology.

How navigable are fluid mud layers?

Safe navigation through ports and waterways is determined by the space available under a ship's keel, but a seabed of fluid mud can get in the way.

Is high quality sediment monitoring worth its weight in gold?
Is high quality sediment monitoring worth its weight in gold?

Dredging activities often result in the suspension of sediment into the water column in the vicinity of the activity. Sediment release to the aquatic environment and the effects of this release are often the prime environmental concern associated with dredging.
