“…This catchment is completely urbanized and has recurrent flood events, including flash floods. The population density is high and therefore it has high risks of people displacement, injuries, and economic losses (Simas, 2017). Additionally, this catchment is well monitored, with rainfall, stream flow, and stage data monitored each 10 min for 10 years by SAISP system (Barros et al, 2016;SAISP, 2023).…”

Abstract. Megacities in developing countries are commonly affected by flooding events. The use of flood models can contribute to an evidence-based decision-making process. For a good representation, these models require physical data for catchment parameterization, and observed data for calibration and validation, which is often scarce. In this study, we analysed the performance results of physically-based (HEC-RAS, CADDIES) and AI-based (LSTM) flood models for two case studies: the Narmada basin in India and the Aricanduva catchment in Brazil. The models were evaluated for accuracy, interpretability, running time, and complexity.

“…The city of São Paulo is a typical location with recurrent flooding problems (Escobar-Silva et al, 2023), for example, in the urban basin of the Aricanduva River, where challenges are frequent and severe, including disruptions in mobility, property damage, loss of lives, injuries, property devaluation, loss of working and leisure hours, health problems, and mental stress (Santos and Haddad, 2014;Haddad and Teixeira, 2015;Simas, 2017).…”

Green roof infrastructure outperforms grey technology in flood mitigation in São Paulo’s urbanized region

São Paulo City, Brazil, a densely urbanized area in a tropical climate region, is facing increasing challenges from flooding. However, a promising solution has emerged in the form of Nature-Based Solutions (NBS) infrastructure, surpassing traditional grey technology in flood mitigation. This article examines the effectiveness of green roofs in reducing flood risks and highlights their superiority over conventional approaches. We analyzed the direct impacts of surface permeabilization in public areas (sidewalks, streets, and squares) and private areas (urban lots, subdivisions) on runoff volume and peak flow in the Aricanduva River basin in São Paulo city. We used a thoroughly validated hydrological model to compare the interference in the land use of the watershed between a green infrastructure type called Green Roof (GR) and a gray technology called Permeable Pavement (PP), in terms of hydrological efficiency in mitigating floods. The flow and water level simulations for varying areas with GR or PP covered a wide range, allowing for situations above or below the canal overflow level, which provided a good distinction of the impact of boundary conditions. Overall, we observed a positive hydrological response, with a reduction in peak flow and runoff volume proportional to the increase in permeable area, and consequently, proportional to the increase in GR or PP surface within the contributing area. As the main contribution, the hydrological performance calculated with the variation of GR was remarkably superior to the variation of PP in terms of requiring a smaller coverage area with interference to prevent overflow or achieve equivalent efficiency. It is worth noting that the substitution of approximately 24% of the gray roof area with GR prevented canal overflow, which is notably lower than the required substitution of approximately 40% for PP interference. We reinforce the relevance of green roofs as an option to mitigate intense hydrological effects in urban areas and, more importantly, paves the way for other NBS with the same hydrological principles and environmental co-benefits to work individually or in combination.

Eles indicam que apenas com a correlação de diferentes componentes físicos e sociais do espaço é viável identificar possíveis áreas de risco(Simas;Rodrigues;Sant'anna Neto, 2017, por sua vez, realizam uma pesquisa na microbacia do igarapé do Quarenta, na Zona Sul da cidade de Manaus-AM.

O presente artigo realiza o estado do conhecimento de temáticas ambientais de uma revista de Geografia, o Boletim Paulista de Geografia (BPG). O objetivo é investigar a abordagem das temáticas ambientais para análise geográfica nos artigos do BPG entre os anos de 2001 e 2021. Realiza-se um breve histórico da importância do BPG em relação ao incentivo do ensino e pesquisa em Geografia. Parte-se de uma pesquisa de abordagem qualitativa: o estado de conhecimento. O corpus de análise é constituído a partir de uma de suas linhas de publicação do BPG: “Geografia Física e Biológica”. Adotam-se os procedimentos da análise de conteúdo de Bardin (1977). Nesse levantamento, foram selecionados 35 artigos que estabelecem o corpus de análise. Inicialmente, correlacionam-se essas publicações às instituições, autores e escala de análise dessas publicações. A partir do quadro dessas pesquisas, observam-se seis eixos temáticos: a) dinâmicas do ambiente; b) planejamento e preservação ambiental; c) impactos ambientais; d) componentes físicos do espaço e suas relações; e) conceitos ambientais; e f) recursos ambientais. Com base nos resultados desse exame, pondera-se sobre as contribuições das temáticas ambientais para formação de professores e bacharéis de Geografia. Sobre isso, verifica-se a composição de um pensamento geográfico que considera conceitos geográficos (espaço, escala e tempo), o axioma geográfico da relação entre a sociedade e natureza e a mobilização de metodologias e da linguagem cartográfica.
