Resumen
This articleaims todescribe the methodology that allows us to represent the roughness in tunnels for its use in physical models. To this end, rough belts were placed along the entire length of the tunnel and separated at specific distances, which resulted in different values of roughness coefficients inside this structure. Currently, there already exist some methods of representing this phenomenon both in open and closed conduits, but thesemethodspresent some difficulties both in the flow behavior itself (due to the presence of some local phenomena)and in the transport of sediments within the ducts. Using these belts, these behaviors would be observed in a reduced physical model.For this reason, representingthe values of the coefficient of surface roughness in physical models using materials that facilitate the visualization of the flow and exact representation of the geometry of the structures motivatedusto investigate a method that allowsusto representthe roughness values for tunnels that work with flow under pressure and gravity
