Abordagem integrada para mitigação de alagamentos em Palmas-TO: estado da arte, árvore decisória e aplicativo de monitoramento

Abstract

This study investigates integrated strategies for flood mitigation in urban areas of Palmas, Tocantins, considering the impacts of unplanned growth and soil impermeabilization on the efficiency of drainage systems. The research is based on a systematic literature review conducted using the Parsifal platform, covering studies published between 2010 and 2024, which mapped the state of the art in both conventional and non-conventional urban drainage solutions, including stormwater galleries, detention basins, infiltration gardens, permeable pavements, green roofs, and digital monitoring tools. From this synthesis, a decision tree was developed to prioritize mitigation measures according to the typology of the affected area, the existing infrastructure, and the severity of the flood, thus supporting decision-making processes at different intervention scales. Additionally, the “Alagou” mobile application was developed using the Flutter framework and Dart language, enabling participatory flood reporting through georeferenced data and real-time images, fostering integration between citizens and management agencies. The results highlight that combining structural and non-structural approaches with mobile technologies and decision- support methodologies enhances stormwater management efficiency and strengthens urban resilience against extreme events, providing technical insights for sustainable planning and adaptive drainage policies.
