Resumen
- An experimental survey study was carried out on hydraulic models in tunnels working as full pipe on composite roughness; the experimental analysis was made with different friction coefficients (that belong to different materials) and compared with values calculated from a proposed theoretical formulation. The model was made for the diversion work of El Cajón hydroelectric project, these criteria also was applied to the Grijalva Tunnels under operation in Mexico and they are also being used for La Yesca hydroelectric project presently under construction
