The determination of the rates of discharge in natural and artificial channels is a hydrometric parameter of utmost importance. However, the complexity of the measurement requires hydraulics to use the techniques of weirs. The type of spillway, its shape and size is a problem, since such a system must provide a permanent flow and a negligible error in the flow calculation. This article presents an experimental study a flow over a weir with a triangular profile. It consists in determining a constant coefficient of discharge in specific areas of headvariations and flows.
