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.
