ANALYSIS OF THE URBAN DRAINAGE SYSTEM OF THE NOVA REPÚBLICA NEIGHBORHOOD IN THE CITY OF SANTARÉM – PARÁ

Abstract

Carrying out a diagnosis of the urban drainage system is an essential basic tool for identifying the causes and proposing solutions for episodes of flooding, inundation and flooding. In Santarém-PA, during the rainy season, these episodes are frequent, especially in the Nova República neighborhood, which has serious urban drainage problems. In this study, the urban drainage system was investigated in order to identify the main causes of failures. For this, the points of flooding and runoff were mapped using a georeferencing tool and consultation of official documents and evaluation of microdrainage devices through on-site visits. Three critical flooding points were identified in the neighborhood, caused by the emergence of irregular occupations, lack of paving on the roads and consequent soil loading into the micro-drainage system, and improper disposal of solid waste that obstruct and compromise the functioning of the devices.
