Hydrological Yearbooks
The Yearbook project involves the digitisation of all data published in the Hydrological Yearbooks since 1921 in order to create a national database.
The project is still ongoing and is due to be completed by the end of the year. An archive in PDF format with scanned images of all the yearbooks (252,548 pages) has been created as an intermediate product.
Each Hydrological Yearbook contains data for a given year and for the area of competence of the Departmental Office of the National Hydrographic Service, responsible for editing and publishing the data concerned.
The Hydrological Yearbooks from 1950 onwards and for most of the previous years are divided into two parts: Part I: thermometry and pluviometry;Part II: rainfall, hydrometry, hydrological capacities and budgets, groundwater levels, sediment load, surveys, ideological studies and exceptional events, tide measurement, marigraphy.
The inquiry process involves selecting the Compartment referred to by the Yearbook that the user wishes to view, followed by Part I or II of the Hydrological Yearbook containing the data to be viewed.
After selecting the Hydrological Yearbook the user can click on the thumbnail image of the page requested in order to view it in pdf format.
