GESTÃO DE ÁGUAS URBANAS: SOLUÇÕES PARA AS INUNDAÇÕES NO SETOR JARDIM AMÉRICA EM GOIÂNIA, COM FOCO NA REGIÃO DA RUA C-107

Abstract

Rapid urbanization in Goiânia, particularly in the Jardim América neighborhood, has led to significant soil impermeabilization, causing frequent flooding and compromising stormwater management. This study aimed to analyze stormwater runoff on Rua C-107, identifying the causes of flooding and proposing effective solutions. Using field surveys and drainage system analysis, which included catch basins of the hat and grill types, it was found that 92.53% of the area is impervious, contributing a runoff of 1.96 m³/s. The catch basins showed a high obstruction rate (42.22%), negatively impacting system efficiency. The total capacity of the devices was calculated at 2.05 m³/s, which exceeded the contribution runoff but was insufficient to handle intense rainfall.Results indicate that obstruction and poor conditions of the catch basins compromise runoff, while those in better condition demonstrated higher efficiency. The analyses reveal the need for interventions to improve the microdrainage system and reduce flood impacts. This work highlights the importance of urban planning that considers the hydrological cycle, aiming to implement absorption and retention solutions for stormwater to mitigate flooding issues and ensure public safety.
