Bio-Engineering Sediment Management And Removal of Turbidity Technologies: BESMART Technologies

At Deltares in the Netherlands, a research team is developing a portfolio of technologies dedicated to the management of the finest and most challenging fraction of soft sediments. These technologies may unambiguously be called nature based because they make use of natural processes to enhance dewatering and strengthening, induce flocculation and the settling of fines, and protect the muddy bed from erosion.

The Smartsediment tool: a QGIS plug-in for evaluating ecosystems services

Managing sediments, especially from dredging, is important for the management of estuaries and coastal areas. When implemented in the right way, a sediment management strategy can be qualified as a nature-based solution as it uses the physical processes of erosion and sedimentation to create added value. There is a need for an evaluation of sediment strategies and the habitats that are created for a wider range of objectives than only biodiversity and nature conservation. The concept of ecosystem services provides this broader framework.

Interview: Stéphanie Groen, Director of Coastal & Climate Change in Asia for Aurecon in Singapore

Stéphanie Groen works as the Director of Coastal & Climate Change, Asia for Aurecon. Based in Singapore, she was appointed to the position at the beginning of 2020. Previously, Stéphanie was involved in marine and environmental projects for more than 15 years with DHI and her education is in civil engineering and business administration. IADC also knows Stéphanie as the winner of the Young Author Award in 2007. More recently, she was appointed as a committee member to the prestigious FIDIC Sustainable Development Committee. We were interested to hear more from Stéphanie – her views on sustainability, the collaboration with the dredging industry through FIDIC and what her new role can mean for sustainable water infrastructure projects.

Land reclamation: The potential for subsurface freshwater storage

At present too little use is made of the opportunities that the design and construction of land reclamation offer for the underground storage and recovery of fresh water. The managed aquifer recharge systems in the coastal dunes of the Netherlands are a good example of successful subsurface water storage. And it is to be expected that the sandy deposits of land reclamations could serve a similar purpose. This in turn will contribute to a sustainable development of land reclamations.
