Hydrographic Survey in Foz do Rio Douro

The Hydrographic Brigade began a hydrographic survey at the mouth of the Douro River, which is part of the responsibilities of the Hydrographic Institute in support of the Navy's operational activity. The objective of the survey is to verify the batimetric evolution in relation to the survey carried out in 2015, in order to assess the conditions of entry for Navy ships to practice entry into the Douro River
