When is a hydrographic survey used?

To explore the seabed, determine the depth by means of acoustic waves properties. Further to find locations of rocks and sand bars for navigation channel opening and salvage operation.

Surveys are also used for designing projects like dams, bridges, reservoirs, ports, harbors, offshore wind farms, and exploring other submarine cable routes.

Which types of echo sounders are being used?

SBES or a Single Beam Echo Sounder:
