Bathymetry would be performed by mean of singlebeam or multibeam echosounder.
The parameter to evaluate the quality of bathymetric survey is the reliability and accuracy obtained (up to 5x5cm by mean multibeam).
Hydrographic surveys for all the marine purposes like dredging, marine construction, seabed habitats monitoring, beaches nourishing, etc, pier and breakwaters inspection..
