The studies developed in a physical model to obtain the flow rate through submerged radial gates are described. The experimental results are used to calibrate and verify a numerical model for computing the water discharge; the numerical model is based on dimensional analysis and the theory of incomplete similarity; the numerical model is useful for calculating the laws of discharge of radial gates, for both free and submerged discharge. First, the physical model of a control structure is described; there are two piles and three radial gates; downstream from the radial gates there are three parallel culverts, with rectangular cross section; after, the process to obtain the law of discharge of the culverts is explained, for the case in which the radial gates are fully open; this law of discharge is adjusted using the experimental measurements. Subsequently, the calculation of the curves of the radial gates with submerged discharge is explain; two recent numerical models that are applicable for free or submerged discharge conditions are presented. The numerical model that best match the experimental results is calibrated and verified.
