Abstract

The use of spillways, such as Parshall and WSC flumes, are widely used for fluid flow measurement, as in Water and Sewage Treatment Plants, measurement of runoff for agricultural purposes. Thus, it has been used in scientific works in which it is necessary to obtain the flow rate, due to measurement accuracy, ease of construction and operation. Therefore, the objective was to dimension and build flumes like Parshall and WSC, and adjust a mathematical model to estimate the drained flow depending on the height of the depth water in these flumes. The experiment was carried out in the Federal University of Grande Dourados in Hydraulics Laboratory, where flow values for flumes were measured by the volumetric method. The data were subjected to the normality test and regression adjustment for potential function. With the results, a good adjustment of the calibration equation was verified, obtaining high values of determination coefficients for the flumes, WSC (R2 = 0.98) and Parshall (R2 = 0.99), the minimum and maximum flows observed were, respectively, 0.039 and 2.23 m3 h-1 for WSC and 0.11 m3 h-1 e 4.44 m3 h-1 for Parshall, meeting the specifications for use in experimental plots with typical weather of the South region of Mato Grosso do Sul State.
