Bathymetric Survey

Bathymetric surveys are a type of hydrographic survey which map out the details of underwater terrain, illustrating the depth and land that lies beneath a body of water. Data can be collected for a variety of water bodies, including rivers, lakes and estuaries, and the data can be used to inform flood assessments and project developments.

Traditionally, Bathymetric surveys are conducted using an echo sounder attached to a survey boat. As the boat moves across the water, the echo sounder will generate electrical signals. These are then converted into soundwaves by an under-water transducer.
