Coast & flood defence
Dunes, levees and coastal defence: land and water in one picture, with profiles checked against the design.
The sector
Coastal defence and flood protection call for reliable figures: how much sand has been spread, how does the levee or dune profile compare with the design, and how does it change over time? One reference is the sand nourishment on Wangerooge (Germany).
How we help
We combine drone surveys (dune body, sand distribution, volume) with the BlueBoat USV (seabed) into one picture of land and water. We measure levee profiles with RTK on a pole and check them automatically against the design, with a sheet per profile on which low and high sections are coloured. That way you follow progress and receive as-built documentation in one report.
