Análisis del riesgo de inundaciones en seis barrios del sur de Quito y planificación de estrategias para la reducción de la vulnerabilidad, cantón Quito 2022- 2023

Abstract

Quito is a city prone to flooding, due to different factors such as the poor state of the sewerage networks, the city is topographically located in a mountainous area with steep slopes, on the other hand, there is also the mountainous part that eventually drain the water towards the lower part causing high rainfall, deteriorated infrastructure, population density and climate change. Many structures in southern Quito have been built on soils with high water tables, steep slopes on the foothills of the hillsides, and settlements without permits, causing high flood risks. The purpose of this investigation is to make a guidance document for the following neighborhoods: San Bartolo, Chimbacalle, La Magdalena, Solanda, La Mena y La Ferroviaria, about the consequences of flooding, so that in the future they can reduce the risk of this natural disaster by a certain percentage, since it does not depend only on the population, it also depends on local authorities and urban planning. The aim is to encourage a change that generates good habits with respect to the care of sewers, a good characterization of domestic waste in homes, construction in neighborhoods that are close to hillsides or rivers, prevent deforestation and finally the most important thing that is directly related to the reduction of environmental pollution. The data were collected through statistical analysis and interpreted in maps elaborated in ArcGIS software.
