Análisis comparativo de los aliviaderos de ladera superficial con evacuación frontal y cerrado con pozo vertical, en los sistemas hidráulicos fluviales de carga pequeña y media

Abstract

The purpose of this project is the comparative analysis of two types of spillways from a regulation reservoir: open margin spillway with frontal evacuation and closed spillway with vertical well, in fluvial hydraulic systems for small and medium loads. Through the elaboration of algorithms through Excel software, performing a dimensioning of the works that are part of each one of the spillways, for flows of gradual or uniform variation; The results obtained were compared, based on the variation of the flow and the load, which are the parameters that have a fundamental impact on the design. It was found that the unit flow constitutes a parameter of fundamental incidence not only in the constructive characteristics of the spillways of the types of surplus spillways but also in their cost; In effect, the increase in the unit flow determines the decrease in the geometric dimensions of the input weir, but not in the dissipation structure, giving rise to the need to carry out a technical-economic analysis to identify the optimal alternative. Within this conceptual framework, the best of the two proposed alternatives for the surplus spillway will be the one selected because of the technical-economic analysis.
