Estudio del sistema de drenaje para la vía Molleturo -Tres Marías- La Iberia, en la provincia del Azuay

Abstract

Considering that the inadequate evacuation of the rainwater flowing over the road could generate damage to its structure, was undertaken a study of the drainage system for the road Molleturo - TresMarías - La Iberia (28.2 km. long, located in the Azuay Province). The analysis and design of the different elements that constitute such drainage system were substantiated in two aspects: (1) A hydrological evaluation of the project area, based on the historical reports from nearby rainfall stations, and (2) A hydraulic evaluation to determine the dimensions that guarantee the proper evacuation of the water flow. The calculations are based on the methodologies of Manning, American Rational and the Soil Conservation Service [SCS], supported by the available computational tools. In the end, the consistency of the results obtained within the standards and the established design parameters, such as the flow carried by the sewers and gutters, the scour depth and the height available for the gauge (obtained with the hydrological modeling of the corresponding channel), guarantee an economical implementation cost beside the efficient execution of this project.
