Os objetivos do presente trabalho consistiram em testar um modelo denominado HYCYMODEL para realizar o estudo do processo chuva-vazão da bacia do Rio das Pedras, região de Guarapuava, Estado do Paraná, Brasil, e obter índices de evapotranspiração relativa (ETr/ETp), a partir das estimativas da evapotranspiração potencial (ETp) com o método de Thornthwaite e evapotranspiração real (ETr) obtidas com o HYCYMODEL, na referida bacia. Os ajustes entre as vazões observadas e estimadas com o HYCYMODEL foram considerados bons quando contrastados com os valores apresentados por outros autores, porém a estimativa da evapotranspiração real (ETr) e, conseqüentemente do balanço hídrico pelo modelo, não foi considerada adequada no presente trabalho. Palavras-chave: HYCYMODEL, processos chuva-vazão, índice de evapotranspiração. ABSTRACT. Study of the rainfall-runoff process in Rio das Pedras watershed, Guarapuava, State of Paraná, with the HYCYMODEL model. The aim of the present work was to characterize the rainfall-runoff process in Rio das Pedras watershed, located in Guarapuava, state of Paraná, Brazil, applying the HYCYMODEL, and get relative evapotranspiration indexes (ETr/ETp), based on the estimations of potential evapotranspiration (ETp), using Thornthwaite method and the real evapotranspiration (ETr) with the application of the HYCYMODEL, in the above mentioned watershed. The adjustments between the observed and estimated runoffs with the HYCYMODEL were considered optimum when compared to the values presented by other authors. However, the valuation of ETr and consequently of the water balance by the model was not considered adequate in this work.
This paper presents the Internet of Smart Grid Things (IoSGT) architecture, which is understood as an ecosystem of cutting-edge technologies that work together to enable advanced SG applications, which run at core/edge cloud datacenter premises connecting an underlying IoT networking infrastructure. The IoT-to-Edge-to-Cloud continuum paradigm that the IoSGT architecture yields aim to accelerate a plethora of Smart Grid (SG) new generation systems, which will advance current facilities at unprecedented levels. We materialized the proposed architecture in the form of a prototype atop a testbed entailing real-world technologies to lay high-accurate experiments assessments. The IoT-to-Edge-to-Cloud continuum of the IoSGT testbed extends from edge datacenter facilities running at the Federal University of Pará (UFPA), and the Federal University of Rio Grande do Norte (UFRN) premises, interconnected by RNP. An IoT-based off-the-shelf Smart Meter has been built by our group to provide a low-cost IoSGT Advanced Metering Infrastructure (AMI) use case. In addition to presenting the IoSGT architecture, our work includes prototyping and exercise on the testbed.
