| Sumario: | A Risk Map is a cartographic representation that allows visualizing the distribution of certain disaster risks in a specific territory, in this case, flood caused by recurrent rainfall. In the present paper a Flood Risk Map was made for the Mar del Plata city’s north sector. Several water and sanitation projects are being developed for Mar del Plata by Obras Sanitarias Sociedad de Estado (OSSE). This Flood Risk Map is coupled with the company’s Geographic Information System to provide detailed risk data for the city’s different sectors. This will be used to manage and plan future projects. This paper shows the Flood Risk Map project’s first stage, which aims to map the entire city and locate high-risk sectors in order to prevent potential conflicts with the company’s infrastructure and possible consequences on the local population. The Sustainable Development Goals of the 2030 Agenda were also taken into account. Using the open source software QGIS, a multivariate analysis was carried out, following local, national and international organizations legal guidelines and recommendations. A Flood Risk Map was obtained for four sectors of the city’s north region, locating different risk areas which were analyzed and corroborated on site and with georeferenced historical photographs of various floods. Among the conclusions there are determined the next steps to be taken to achieve a Flood Risk Map of the entire Mar del Plata’s urban-grid and how to expand the project to the peri-urban sectors of the General Pueyrredon Partido. |
