Scour survey

Due to the faster water flow around construction piers, deep scours can develop. They can threat the structure itself. Bathymetry surveys are therefore a must for assessing the dimensions and evolution of scour development and evaluate the associated risks.

For a proper understanding of scour development and evolution we recommend full swath coverage using multibeam or interferometric sonars. It provides good quality data, valuable in understanding bottom morphology and the necessary tools for the quantification of the eroded volume of sediments. Microbathymetry offers information regarding how much the structure is exposed by erosion processes.
