Potential of the LASH model for water resources management in data-scarce basins: a case study of the Fragata River basin, southern Brazil

Abstract: The objective of this study was to evaluate, based on a data-scarce basin in southern Brazil, the potential of the Lavras Simulation of Hydrology (LASH) model for estimating daily streamflows, annual streamflow indicators and the flow-duration curve. It was also used to simulate the different runoff components and their consistency with the basin physiographical characteristics. The statistical measures indicated that LASH can be considered suitable according to widely used classifications and when compared wi… Show more

“…LASH is a deterministic and semi-conceptual rainfall-runoff model developed by researchers from the Federal University of Lavras in partnership with the Purdue University (USA) and currently with the participation of researchers from the Federal University of Pelotas. This hydrological model has been successfully applied in several watersheds (BESKOW et al, 2011;VIOLA et al, 2013;BESKOW et al, 2013;VIOLA et al, 2014;BESKOW et al, 2016b;CALDEIRA et al, 2019).…”

“…Neste sentido, destaca-se o conceito de equifinalidade, que é a existência de vários conjuntos de valores de parâmetros que proporcionam resultados satisfatórios e bastante semelhantes entre si, sendo impossível distinguir a melhor combinação (BEVEN, 2004). A equifinalidade, segundo Her e Chaubey (2015), vem sendo, nas últimas três décadas, bastante discutida na literatura associada à modelagem hidrológica (SOROOSHIAN; GUPTA, 1983;BINLEY, 1992;GAN;BIFTU, 1996;FREER, 2001;VRUGT;BEVEN, 2018 Daggupati et al (2015), pode ser realizada, basicamente, por tentativa e erro (calibração manual) ou por métodos automáticos.…”

“…Neste sentido, destaca-se a técnica de regionalização hidrológica, a qual permite transpor informações de bacias hidrográficas monitoradas para o local de interesse, dentro de uma região hidrologicamente homogênea, não monitorado ou com série histórica de curto período de tempo (BESKOW et al, 2016a). Esta técnica atende demandas como estimativa de vazão média de longo termo, vazão máxima anual, vazões de referência da curva de permanência, etc., no entanto, apresenta dificuldades e limitações, principalmente associadas à necessidade de se ter uma região hidrologicamente homogênea e à inviabilidade de transposição da cronologia de ocorrência dos dados monitorados, isto é, de fornecer informações em uma escala temporal mais detalhada.…”

“…Ideally, peak stream flows are estimated from historical series originated from the hydrological monitoring in the outlet of interest. However, Beskow et al (2016a) point out that the unsatisfactory density of gauging stations operating in developing countries (e.g Brazil), associated with short time-series available, especially in small and medium-sized basins, hamper the analysis, thus leading to the use of indirect methods to estimate hydrologic variables. In this context, hydrological regionalization can be applied on gauged sites, in order to add information to the existing series, as well transfer them to ungauged locations for the sake of meeting the data demands (BESKOW et al, 2016b).…”
