Top-hydrographic survey on the Mondego River

A top-hydrographic survey was carried out on the Mondego River in Coimbra during the week 18-22 February to support the celebrations of the 2019 Navy Day.

The survey consisted of a survey with a simple acoustic beam system in which parallel wires were made to each other spaced 25 meters in order to raise the bottom of the river, i.e. to know the depths there.

This action was complemented with topography works on the margins.
