“…The SWAT model, developed by the USDA Agriculture Research Service, is designed to model hydrology at the scale of a watershed [36]. The SWAT model is structured on fundamental components of action, such as: Climate, hydrology, sediment, nutrients and management [51][52][53] and can be used to predict the variation in these components by change in land use and climate. SWAT follows a defined operating sequence; (1) data preparation, (2) discretization of sub-basins and definition of HRUs, (3) sensitivity analysis, (4) parameter calibration and (5) validation.…”

“…Based on previous studies, 20 hydrologic parameters were considered ( Table 5). These parameters were described according to their existence among the main flow rate variable calibration parameters [51]. SUFI-2 begins with wide ranges of meaningful parameters that capture most of the observed data within the 95PPU and then iteratively decreases the uncertainty of the parameters [69].…”

The change in both streamflow and baseflow in urban catchments has received significant attention in recent decades as a result of their drastic variability. In this research, effects of climate variation and dynamics of land use are measured separately and in combination with streamflow and baseflow in the Little Eagle Creek (LEC) watershed (Indianapolis, Indiana). These effects are examined using land-use maps, statistical tests, and hydrological modeling. Transition matrix analysis was used to investigate the change in land use between 1992 and 2011. Temporal trends and changes in meteorological data were evaluated from 1980–2017 using the Mann–Kendall test. Changes in streamflow and baseflow were assessed using the Soil and Water Assessment Tool (SWAT) hydrological model using multiple scenarios that varied in land use and climate change. Evaluation of the model outputs showed streamflow and baseflow in LEC are well represented using SWAT. During 1992–2011, roughly 30% of the watershed experienced change, typically cultivated agricultural areas became urbanized. Baseflow is significantly affected by the observed urbanization; however, the combination of land and climate variability has a larger effect on the baseflow in LEC. Generally, the variability in the baseflow and streamflow appears to be heavily driven by the response to climate change in comparison to variability due to altered land use. The results reported herein expand the current understanding of variation in hydrological components, and provide useful information for management planning regarding water resources, as well as water and soil conservation in urban watersheds in Indiana and beyond.

“…In addition, they also pointed out that substantial baseflow is essential to maintain sound stream ecosystems in the LEC watershed. In their attempt to minimize the runoff impact of urbanization in the LEC, Tang et al [41] [29,44,45,46] and can be used to predict the variation in these components by change in land use and climate.…”

The change in both streamflow and baseflow in urban catchments has received significant attention in the latest decades as a result of their drastic variability. In this research, effects of climate variation and dynamics of land use are measured separately and in combination on streamflow and baseflow in the Little Eagle Creek (LEC) watershed (Indianapolis, Indiana). These effects are examined using land use maps, statistical tests, and hydrological modeling. Transition matrix analysis was used to investigate the change in land use between 1992 and 2011. Temporal trends and changes in meteorological data were evaluated from 1980-2017 using the Mann-Kendall test. Changes in streamflow and baseflow were assessed using the Soil and Water Assessment Tool (SWAT) hydrological model using multiple scenarios that varied in land use and climate change. Evaluation of the model outputs showed streamflow and baseflow in LEC are well represented using SWAT; however, comparing the calibration and validation period showed SWAT performs better for the calibration. During 1992-2011, roughly 30% of the watershed experienced change, typically cultivated agricultural areas became urbanized. Baseflow is significantly affected by the observed urbanization; however, the combination of land and climate variability has a larger effect on the baseflow in LEC. Generally, the variability in the baseflow and streamflow appears to be heavily driven by the response to climate change in comparison to variability due to altered land use. The results reported herein expand the current understanding of variation in hydrological components, and provides useful information for management planning regarding water resources, as well as water and soil conservation in urban watersheds in Indiana and beyond.

“…The results of the calibration step (2006 until 2009) and validation (2010 until 2015) of the monthly streamflow (m 3 /s) for each one of the analyzed gauging stations can be seen in Figure 5. It is noticeable that both in the calibration period and in the validation one, the SWAT model exhibit a great adjustment, according to the classification written by Almeida et al (2018). In which the model is considered great if 0.75 < NS < 1.00, |PBIAS| < 10 and 0.75 < R 2 < 1.00.…”

RESUMO Este trabalho teve como objetivo avaliar os impactos das alterações do uso e cobertura do solo na bacia do rio Paraíba do Sul utilizando o modelo SWAT. Foram avaliados dois cenários de uso e cobertura do solo, um referente ao ano de 1986 e outro ao ano de 2015. Os resultados mostraram que o modelo SWAT se ajustou muito bem a bacia, após a calibração e validação. Além disso, observou-se que no cenário de 2015 a vazão de longo período, foi inferior em grande parte da área de estudo, com destaque para as sub-bacias no trecho do rio Paraibuna. Notou-se que as alterações no comportamento da curva de permanência foram mais representativas nas estações do rio Paraibuna e do rio Preto. Que na primeira, devido a diminuição da área de floresta, as condições de seca e de vazões mínimas foram intensificadas. Já na segunda, a disponibilidade hídrica melhorou no cenário de 2015, devido ao aumento da área de floresta. Por fim, os resultados aqui apresentados juntamente com o modelo SWAT calibrado podem servir de auxílio aos gestores de recursos hídricos atuantes na bacia do rio Paraíba do Sul e para futuros trabalhos que visem avaliar, também, os impactos das mudanças climáticas sobre a vazão.
