In the past decade, there have been noteworthy advances in case law with respect to adverse physical conditions as well as the development and use of digital ground models that have become more widespread. This article looks at the development and changes in risk profiles that may result due to these two developments.
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.
Multicopters, unmanned aerial surveyors, can fly and take pictures in difficult-to-reach or potentially dangerous areas, improving the speed and safety of acquiring data.
Removing sediments with high dioxin concentrations requires extra care, with modern surveying and tracking techniques from beginning to end, from dredging to a high-tech dewatering process to the final disposal.
