For the annual report on the behavior of the dams, which the owners/managers/operators of these infrastructures, have to present to the corresponding organizations or hydrographic confederations, it is necessary to carry out a high-precision topographic control of dams and their associated infrastructure.

For more than 5 years, Topofor has been in charge of controlling the topographic networks of Naturgy dams in Spain, a total of 22 facilities. In these facilities, different types of controls, high-quality leveling, precision, collimations, triangulations and radiations.

Some of the dam control networks have been controlled for more than 40 years old, other networks being more recent, in which Topofor has participated in its design. This is a periodic job, in which the dam facilities are visited to perform topographic measurements, and generate the corresponding reports, in which the behavior of the prey over time is collected through comparisons in data tables and graphs. The generated report is incorporated, as an annex, to the structural safety report of the dams.
