“…In contrast, the radon concentration from the sediment matrix could increase with depth within the hyporheic zone (Gilfedder et al, 2019;Peel et al, 2022). We sampled from the upper first 20 cm of the river et al (2019), radon concentrations of the sediment matrix in this study were slightly higher than groundwater samples of BS1 and BS2 of similar concentration (Table 2).…”

“…In contrast, the radon concentration from the sediment matrix could increase with depth within the hyporheic zone (Gilfedder et al, 2019; Peel et al, 2022). We sampled from the upper first 20 cm of the river bed, while Gilfedder et al (2019) used radon concentrations from samples taken at 1 m depth.…”

“…In previous studies, the geological or hydrogeological conditions were considered a key factor determining the spatial variability of LGD (Peel et al, 2022; Sun et al, 2022). The groundwater around Tangxun Lake correspond to various types with a complex distribution, which may be an important factor for the spatial variability of LGD (Figure 1d).…”

“…The study site at the outlet of the upper Emme valley, a 194 km 2 alluvial headwater catchment in the Swiss Pre‐Alps (Figure 1a), has already served for multiple hydrogeological studies and is equipped with an extensive monitoring network (Figura et al., 2011, 2013; Käser & Hunkeler, 2015; Kropf et al., 2014; Lapin et al., 2014; Moeck et al., 2022; Peel et al., 2022; Popp et al., 2021; Schilling, Gerber, et al., 2017; Tang et al., 2018). GW is abstracted on a floodplain from 8 wells located 150–250 m away from the Emme river (Figure 1a).…”
