FLUVIAL EMBANKMENTS IMAGING

Kinematic survey: no more single investigations

We search and identify any discontinuity that may cause embankment’s failures such as permeable granular sediments, animal dens and piping phenomena.

Adastra Engineering conducts kinematic surveys that allow the embankment to be continuously mapped, for tens or hundreds of kilometers, with productivity that can exceed 20 km per day.

The adopted technologies ensure the survey of the entire embankment body (unlike coring and CPT that are limited to the single investigated point), at significantly lower costs.

The company has a specific experience in the study of embankments, having to its credit some hundreds of kilometers of banks already investigated on behalf of various Public Administrations.

  • Identification of galleries created by animals
  • Cost reduction
  • Three-dimensional reconstruction of anomalies

MODULAR SURVEY TECHNIQUES

A tested survey protocol has been applied on hundreds of kilometers of embankments already detected. It provides three phases of the study using cutting-edge technologies.

  • The embankments are entirely detected with the IDS Stream X wheeled georadar (able to mount up to 40 antennas) which allows a very high three-dimensional resolution of the subsoil. It is particularly effective in identifying tunnels dug by animals.
  • It follows the survey on the entire stretch investigated with the Dualem 642s electromagnetic system which allows identification of textural discontinuities or granular deposit nuclei present in the embankment down to 10 meters deep.
  • Finally, the targeted use of three-dimensional geoelectric survey systems in presence of anomalies ensure the identification of the internal discontinuities of the banks.
  • The use of geodetic GPS and Total Station allows a centimetric geo-referencing of the geophysical surveys and very accurate reconstructions of the embankment’s morphologies.

ASSISTANCE DURING PLANNING

Our company employs technical personnel and a network of consultants from research institutions and universities with a long and consolidated experience in the field of geophysics and hydraulic engineering.

We are therefore able to effectively assist the Clients in all stages of testing, the ordinary and the extraordinary maintenance of the embankments.
