Spatial Analysis of Urban Areas Flooded by Torrential Rains: Study of Flooding Occurrences in the Urban Area of Feira de Santana - Softcover

Inhaltsangabe

This work arises from a point of interest of a socio-economic and cultural nature initiated through extension research carried out at the State University of Feira de Santana (UEFS), a Brazilian public institution of higher education based in the city of Feira de Santana, located in the agreste region of Bahia. A spatial analysis of the areas affected by extreme hydrological events in the city of Feira de Santana (BA) was carried out by spatialising rainfall data from weather station 83221 (INMET/UEFS) from 2016 to 2017 and associating it with the distribution of flooding events provided by the Civil Defence of Feira de Santana. The spatial analysis of events revealed the existence of more vulnerable areas in the urban space, with chronic problems. In this way, the integration of an information system has made it possible to establish a hierarchy in decision-making in relation to the city's most critical drainage points, helping the Civil Defence and City Hall to act.
