“…The heterogeneity is related to its physical characteristics, being well-karstified, with a high density of endo and exokarstic landforms and areas where a thick epikarst can be observed (Pereira et al, 2019). Moreover, Lucon et al (2020) and Assunção et al (2023) confirm in the area the concentrated recharge and rapid groundwater circulation. The presence and importance of this flow in the springs' hydrograph (which some authors add to rapid flow, considering them as a single flow) is well documented (Kiraly et al, 1995;Paiva & Cunha, 2020;Schwartz et al, 2013;Williams, 2008).…”

“…The groundwater is predominantly classified as calcium bicarbonate type. Some anomalies related to anthropogenic factors (such as nitrate and chloride) and geogenic factors (e.g., cadmium) have been observed, being attributed to agricultural and livestock activities as well as the composition of the geological framework, respectively (Lucon et al, 2020).…”

“…In arid to dry sub-humid regions, there are in fact a number of karst basins with few or no hydrological knowledge about flooding processes [1,47], which cannot be identified with search engine inquiries. This is, as an example, the case of the seasonally water deficient Rio Sao Miguel Catchment (South East Brazil) [94], a sub-basin of the Rio Sao Francisco Basin (as the Rio Verde Grande Catchment, previously mentioned in Section 4.4).…”

“…Também foi identificado que a água subterrânea da bacia hidrográfica do rio São Miguel, afluente do rio São Francisco, é derivada da recarga direta da precipitação local, durante o período chuvoso, bem como de áreas com recarga moderna, havendo interações diretas entre água subterrânea e superficial por meio do relevo cárstico, promovendo processos de recarga e descarga ao longo da bacia hidrográfica (LUCON 2018, LUCON et al 2020.…”
