Abstract
Open-channel flows are characterized for having a free surface open to the atmosphere, having a great number of practical applications in engineering. The characterization of the flow in an open-channel depends on a variety of factors, such as: the fluid, flow area, flow rate, flow depth, bed slope and the surface roughness of the channel material. This paper is based on the experimental study of a tests section in a hydraulic open-channel with a rectangular cross-section operated with water as the work fluid. The aforementioned parameters are extensively analyzed via experimental tests. In general, it was observed that the flow was practically turbulent and supercritical during the testing period. The water level was reduced by half as the channel slope was increasing. The average for the Manning and the Chézy coefficients were, respectively, 0.00784 e 59.1.
