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.
A review of survey and monitoring techniques as well as specialised environmental systems are realised in an "ideal" vessel.
