2D-3D BATHYMETRIC SURVEYS

Tecnologiepm performs bathymetric sea and river surveys, with particular reference to three-dimensional bathymetric surveys of the seabed: these surveys are fundamental both for the integration and new positioning of anti-erosion barriers and for fluvial port modelling.

We operate with an integrated and certified instrumental system positioned on a boat: this modus operandi guarantees certainty of the layout information, which is acquired – thanks to an ‘EMU’ – even in rough sea or water basin conditions. We guarantee our customers the possibility of direct verification of the water bed itself with the aid of a team of specialised divers and using a hyperbaric bell.

Our continuous investment in the analysis and development of new survey technologies and methodologies, over two years ago led us to undertake research into modelling of water beds characterised by the presence of overlying fluids. Tecnologiepm has thus been equipped with a double-multi beam system complete with related GPS data: NMEA data are correlated with the relevant information of the return signal. In this way, a modelling of the water bed under examination is constructed: georeferenced quotas are defined which are useful for: monitoring of erosion factors; management of fluvial-lacustrine and marine sites; bathymetric support for reclamation of sea – river – lake sites; and modelling of water flows in the study of hydroelectric plants.

The high reliability of the data and information collected – and the related low costs – are Tecnologiepm’s strong point: a streamlined structure where its surveys – always in compliance with the necessary safety procedures – are competitive compared with those entrusted to ships with complex instrumental diagnostics, also thanks to the standards of access with the boat that cannot be achieved by excessively large vessels.

The following are the main sectors of application identified:

  • Monitoring of coastal marine erosion
  • Fluvial modelling
  • Lacustrine modelling
  • 3D survey for environmental reclamation
  • 3D riverbed modelling for hydroelectric plants
