Delve into this issue’s articles about muddled sediments, an eco-tie-in, Scheldt saver and a lake reviver.
Popular instruments in the field, optical backscatter instruments (OBS) are used to measure suspended sediments. But optical backscatter monitoring presents challenges in mixed sediment environments. The sensitivity of OBS measurements in relation to grain size and the applicability of OBS measurements in mixed sediment environments is analysed.
To connect Scandinavia with Germany, the world’s longest immersed tunnel will be built. The Fehmarnbelt will close a major gap in the European transport network while fostering the development of new nature and recreational landscapes. The infrastructure will close a major gap in the European transport network, reduce the risk of shipping collisions, energy consumption and create a new region in Europe, while also fostering the development of new nature and recreational landscapes by Working with Nature concepts.
IADC speaks with Patrick Meire – Chair of the Biology Department at University of Antwerp – who is dedicated to understanding the delicate and intertwined estuarine ecosystem of the Scheldt estuary and turning research into action to combat threats from human activities and sea level rise.
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 with what has long been considered undesirable dredged material. The archipelago situated within the Markermeer enables processes which revitalise the natural ecology.
