Metodologia de análise de pontos de alagamentos em áreas urbanas com o uso de geotecnologias: o Caso da cidade de Santarém (Pa)

Abstract

The evolutionary moment that our society lives today is characterized by a very dynamic and fast technological evolution, which several authors characterize as the technical informational scientific medium. Following this dynamic, urban sprawl also emerges as a serious problem, while geotechnologies also follow this dynamic and speed, emerging as a great tool capable of assisting in decisionmaking and territorial urban planning. In this context, the present work aims to make a small sample of how geotechnology tools, with emphasis on GIS (Geographic Information System), are able to assist in the analysis of problems such as urban flooding in the city of Santarém - PA. It was used as altimetric base of the city, the TOPODATA project MDE, together with the shapefiles of streets, neighborhood boundaries and finally, the flooding points, thus creating a thematic map. In this sense, it was made an analysis of the topography of the urban area with the flooding points, thus making a spatialization of the problem and an investigation of the possible causes seeking to take into account the peculiarities of each situation. At the end of the work it was concluded that the use of geotechnologies is of fundamental importance for urban planning and that they should be much more used by public management in the city of Santarém.
