  rdf:value "Estructura sobre o a través de la cual se descarga un flujo desde un tanque. Si el caudal se controla mecánicamente con puertas, por ejemplo, se trata de un drenaje controlado. Si la geometría del desagüe constituye el único control, se le considera un desagüe no controlado."@es, "A structure over or through which flow is discharged from a reservoir. If the rate of flow is controlled by mechanical means, such as gates, it is considered a controlled spillway. If the geometry of the spillway is the only control, it is considered an uncontrolled spillway."@en ;
