Aprovechamiento del río Carcarañá-Tercero como vía fluvial navegable. parte II

DISEÑO HIDRÁULICO DE PRESAS DE NAVEGACIÓN

Abstract

Planning, design and detailed engineering of a navigation dam (as part of a comprehensive project of a river transport pathway) jointly comprise a complex and multidisciplinary set of several fields of engineering. Such waterworks are composed typically of a group of structures that work together in order to ensure level requirements in the sections between dams, allow the passage of ships through the uneven water levels generated by the dams and allow controlled runoff. They can likewise be considered for other purposes such as irrigation, water supply and hydroelectric power generation. This paper focuses on the hydraulic and geometric preliminary design of the main components of the navigation dams that have been proposed in the prefeasibility study for the use of the Carcarañá River as a navigable waterway. We present the hydraulic configuration considered for the navigation, the distribution of navigation dams and the preliminary design of the spillway, the gates and the energy-dissipating devices. Advances in the preliminary design of structures were kept accordingly to the overall context of the prefeasibility study of the project. The results achieved made possible the quantification of the magnitude order of the minimum volume needed by the infrastructure for this type of work, setting a framework rigorously necessary to proceed with a subsequent draft level approach.
