Applications of geophysical techniques to improve a groundwater conceptual model in an outcrop area of the Guarani Aquifer System, in Brazil

Understanding hydrological connectivity: an empirical study of river-aquifer interaction across Brazil

“…In fact, the outcrop region of the GAS in São Paulo, Brazil, concentrates much of the river-aquifer interaction studies in the country. For example, Batista et al (2018) indicating that most stretches of the river showed an influent condition, meaning the stream recharges the aquifer, stream discharge data suggested that the river analyzed would predominantly be a losing river, in line with previous works (Melo & Wendland, 2017;Coutinho et al, 2020). This highlights the importance of using more than one technique for these studies.…”

Experimental and representative watersheds as a training site of qualified professionals in water resources: a case study of Onça Creek Watershed (SP, Brazil)

“…OCW has a annual mean rainfall of approximately 1500 mm and a mean air temperature of 21.6 ºC (Cabrera et al, 2016). Considering the soil pedological classification, OCW is covered mainly by an ortic quartzarenic neosol, with sandy texture in the entire profile (Coutinho et al, 2020). Other types of soils are also founded at the OCW (Figure 3).…”

“…• the application of geophysical techniques, which helped to improve the watershed conceptual model, in terms of different hydraulic conductivity regions and boundary conditions (Coutinho et al, 2020).…”
