Metodología para Evaluación de Drenajes Urbanos en Vías Urbanas de Ciudades hasta 300000 habitantes, 2020

Abstract

The investigation involves the drainage problems that end in the flooding of the urban roads of the city, for this reason a methodological proposal is developed for the evaluation of urban drainage in urban roads of cities up to 300,000 inhabitants, in order to reduce the risk to floods. The importance of the research is based on the theoretical limitation and the little knowledge available on studies for evaluations of urban drainage related to road flooding. Where the problem we pose is How to Evaluate urban drainage to prevent flooding in urban roads? For this, we set ourselves the objective of evaluating urban drainage, through a methodology that assesses its state to avoid flooding in urban roads of cities with up to 300,000 inhabitants. Thus, data and criteria for urban drainage and flooding in urban roads were obtained through bibliographic research and investigative background, such as risk assessment through the analysis of vulnerability, threat and exposure, which are divided by physical, economic, environmental components., social, in addition to meteorological, hydrological, human factors, land use and evaluation of the drainage system. The information collected was data from the public company applying documentary analysis directed towards maintenance work, proposals and projects carried out by public officials and background in investigative work related to the dangers of flooding in certain areas of the city. Once the necessary data on the urban drainage of the city of Machala were collected, where the case study was the area delimited by the streets Circunvalación Norte, Guayas, Marcel Laniado and 10 de Agosto, results were obtained that allowed knowing the current state of operation. of the urban drainage system where a vulnerability value of 0.7/1, threat 0.6/1 and exposure of 0.75/1 were found, giving a total rating of 2.05/3, which indicates that urban drainage has a high risk to floods and improvements should be implemented in most of the indicators evaluated in the research work.
