“…This same behavior was identified by Costa et al (2014). These authors applied the regionalization methodology of duration curves for watersheds in the states of Minas Gerais and Ceará, recording a greater difficulty in obtaining good results in the case of intermittent rivers.…”

Despite the advances undertaken in recent years, modeling watershed’s hydrological responses remains a complex task, especially in data-scarce areas. In order to overcome this, new models with distinct representations of hydrological processes continue to be developed, incorporating spatial data and geoprocessing tools. In this article, the CAWM IV (Campus Agreste Watershed Model Version IV) model is presented. It is a conceptual model developed with the purpose of contributing mainly to the hydrological modeling of basins inserted in semi-arid regions. The article provides the layout of the mathematical model structure and a set of results obtained from the application of the model to basins with different characteristics. The main features of the model are the reduced number of parameters to calibrate and the incorporation of the basin physical characteristics in the calculation of several attributes, in order to facilitate the process of regionalization for other similar basins, particularly due to the absence of flow data. The CAWM IV model was applied to four basins located in the state of Pernambuco, in the Northeast region of Brazil. The model presented adequate behavior for 55 to 92% of the simulated events, depending on the criteria of performance indicators used in the analysis.

“…Finally, all qualified parameter sets would be further evaluated for prediction in ungauged catchments. At the early post‐PUB decade, there were some studies which applied this method (Costa, Fernandes, & Naghettini, 2014; Pinheiro & Naghettini, 2013; Shu & Ouarda, 2012; Westerberg et al, 2014). However, this research has been relatively rare in the post‐PUB decade since it is more complex and might be limited by the accuracy of meteorological data compared with direct regionalization of hydrological signatures (H. E. Beck et al, 2016).…”

Runoff prediction in ungauged and scarcely gauged catchments is a key research field in surface water hydrology. There have been numerous studies before and since the launch of the predictions in ungauged basins (PUB) initiative by the International Association of Hydrological Sciences in 2003. This study critically reviews and assesses the decadal progress in the regionalization of hydrological modeling, which is the major tool for PUB, from 2000 to 2019. This paper found that the journal publications have noticeably increased in terms of PUB in the past 7 years, and research countries have been expanded dramatically since 2013. The regionalization methods are grouped into three categories including similarity-based, regression-based, and hydrological signature-based. There are more detailed researches focusing on the interdisciplinary and profound improvement of each regionalization method. Namely, tremendous efforts have been made and lots of improvements have been carried out in the parameterization domain for the post-PUB period. However, there is still plenty of room to improve the prediction capability in data-sparse regions (e.g., further verification and proof of multi-modeling adaptation and uncertainties description). This paper also discusses possible research directions in the future, including PUB in a changing environment and better utilization of multi-source remote-sensing information.

“…For these it is verified that the models did not properly reproduce the recorded flows. This behavior was identified by Costa et al (2014) in the application of the regionalization method by synthetic permanence curve for Ceará basins with daily data. Probably this is due to the inadequacy of general models used in both cases (MODHAC and Rio Grande).…”

“…Several authors proposed the regionalization of flow permanence curves as the hydrological response or one of the "signatures" of the watershed (LIU;HAN 2010;PINHEIRO;NAGHETTINI, 2010;WESTERBERG et al, 2011;PRAFULLA;YILMAZ;GUPTA, 2012;COSTA et al, 2014). In this last article, the authors use the regionalization methodology of permanence curves for watersheds in two Brazilian regions.…”

RESUMO Este estudo analisa a regionalização de parâmetros de modelos hidrológicos em regiões semiáridas com escassez de dados, tendo como foco parte do semiárido brasileiro que envolve os Estados do Ceará, Rio Grande do Norte, Paraíba e Pernambuco. O modelo hidrológico adotado foi o MODHAC - Modelo Hidrológico Auto-Calibrável. Foram selecionadas 45 estações fluviométricas com um mínimo de oito anos consecutivos de dados consistidos a partir do ano 2000, além dos registros de anos anteriores. O principal critério para regionalização foi a proximidade entre as estações fluviométricas disponíveis, sendo também avaliada a escolha com base em propriedades físicas e climáticas para algumas estações. Foi feita análise de fatores que afetam a qualidade das séries de vazões, bem como da rede de monitoramento pluviométrico. A influência de reservatórios sobre esses dados e a desativação de muitas estações de monitoramento das precipitações foram os problemas mais frequentes. Considerando diferentes indicadores de desempenho, como o Coeficiente de Nash para a raiz quadrada das vazões satisfatório em 63% dos casos, de acordo com valores de referência apresentados na literatura, o procedimento teve razoável sucesso para quantificar as vazões mais elevadas e médias, porém não apresentou em geral bom ajuste das vazões mais baixas.
