Abstract : Three models were used to study portions of the -velocity reached within the Rio Puerto Neuvo basin. A 1:35-scale model of the Puerto Nuevo Channel was tested to determine the flow conditions in the transitions and curves in the supercritical channel, at the junctions with the Guaracanal Channel and Buena Vista Diversion Channel, at the bridges, and in the reach of channel where the flow transitions from supercritical to subcritical flow. Tests were conducted on a 1:25-scale model of the Josefina Channel to determine the flow conditions at the junction with the Dona Ana Channel and where the flow transitions from supercritical to subcritical flow. A 1:35-scale model fo the Margarita Channel was also studied to determine the flow conditions in the vicinity of the De Giego Expressway Bridge and where the flow transitions from supercritical to subcritical flow.
