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.
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.
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
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.
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.
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.
To manage costs and the long-term effects of dredging in highly dynamic estuarine areas, continued scientific research, modelling and analysis are indispensable.
