Studying the performance of LID devices on a laboratory scale has the advantage of flexible layouts, so that more factors can be tested. However, they do not always correspond to what happens on a real scale of application. This paper focuses on a comparative analysis between two bioretention experimental devices considering field and laboratory scales. Based on this comparison, our understanding can be enhanced to extrapolate the results. Flow rate and duration were used as the main equivalence parameters. However, these parameters were insufficient to ensure similarity in the results. We proposed to include control volume, an application rate and an equivalent net depth as new parameters. Further research should test the variation of these parameters.Keywords: SUDS; Stormwater control; Water retention; Pollutant removal.
RESUMOEstudos da performance em laboratório possuem a vantagem de layouts flexíveis, podendo testar mais fatores. No entanto, nem sempre correspondem ao que acontece na escala real de aplicação. Este estudo foca em uma análise comparativa entre dispositivos experimentais de bioretenção em escala de campo e em escala de laboratório. A partir dessa comparação, é possível avançar na compreensão para extrapolação dos resultados. Como principais parâmetros de equivalência, foram utilizados a taxa de fluxo e a duração. No entanto, observou-se que estes parâmetros foram insuficientes para garantia de similaridade nos resultados. Indicamos como novos parâmetros a serem incorporados o volume de controle, taxa de aplicação e altura equivalente útil. Novos estudos com a variação destes parâmetros devem ser feitos.
RESUMOshow that results are substantially affected by spatial resolution of data and the methodology for obtaining primary indicators. It was also observed that the method to obtain and classify spatial data is crucial to identify the relations between each sanitation component and the incidence of a specific disease, as well as their spatial extent. Within the area studied, most diagnosis are attributed to dengue, hepatitis and leptospirosis, especially dengue over the others. Results were mapped in the studied area by census tract.
Nature-based Solutions (NbS) are presented as an alternative and decentralized solutions with different application scales for problems addressed to urban expansion as water quality reduction and floods. The usage of control strategies and mathematical modeling techniques has shown promising results for optimizing hydraulic and water treatment processes. The Digital Twins (DT) as process integration technology are widely used in industry, and recently these technique usages in urban water systems are showing effective results in both management and planning. However, there is a lack of proper literature definition for DT applied to NbS, especially for stormwater and transboundary water security projects. Thus, this paper sought through a literature review to access the existing conceptual challenges and the DT definition as a framework, identify how the mathematical modeling reported in the literature can improve the DT development, and evaluate the potential benefits associated with the application of DT in NbS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
