Screens declogging system of the Golo torrent water intake (France)

Verification of a declogging system at scale 1

Client: Office d’Equipement Hydraulique de Corse - Model scale: 1:1

Context

In order to check the operation of the declogging system of the Golo torrent future water intake, the Office of Hydraulic Equipement of Corsica has commissioned ARTELIA with a full-scale model study of the planned device for the screens cleaning.

Aims of the physical model

The aims of the physical model are:
  • Characterisation of the declogging effect obtained by the counter-current system;
  • Identification and tests of the device adaptations (position, operating discharge and pressure).

Description of the physical model

The physical model represents:

  • One screen of the screens plan;
  • Channel portion in front of the screen to reproduce actual velocity conditions (previously determined by 3D numerical model);
  • Declogging system : submerged water cannon.
