We use our 3D Multibeam system to carry out bathymetric surveys. Our specialised instrument uses a multibeam sonar and a sound velocity probe to map the basin and then provides images of the size, distance and shape of objects on the bottom to an accuracy of cm.

Sometimes, a river can ramify due to the large amount of sediment it carries and continue its journey between the many small islands it has formed. This is called river braiding.

Prior to the construction of the pedestrian bridge of the National Athletics Stadium, we carried out a riverbed survey on the affected section of the Ráckeve (Soroksár) Danube.

As part of the renovation project of the Chain Bridge, which started in 2021, we removed debris from the Danube riverbed.
