O impacto da drenagem sustentável no controle de enchentes na cidade de Goiás - GO

Abstract

The city of Goiás, recognized as a UNESCO World Heritage Site, has faced constant problems related to flooding since its beginnings. These recurring events are directly linked to a combination of historical, geographical and urban factors. These include the inappropriate choice of the site where the city was originally established, the disorganized urban growth over the years that has made the situation even worse, and the morphology of the region marked by the presence of hills and mountains around the urban core, which favor the rapid flow of rainwater towards the river. These natural elements, coupled with the lack of adequate drainage infrastructure, make Goiás particularly susceptible to flooding. Throughout history, major floods have been recorded in 1782, 1839 and 2001. The latter, in particular, had a significant impact on both the social aspect and the city's historical heritage, highlighting the urgent need for effective interventions. Given this scenario, this research proposes an analysis of the feasibility of implementing a Sustainable Urban Drainage System (SUDS) as a possible solution to mitigate the impacts of flooding in Goiás. The aim is to assess how solutions based on sustainability can be adapted to the specific characteristics of the city, in order to preserve its historical and cultural value, while ensuring greater safety for the local population.
