“…Indeed, the riparian zone is generally regarded to be of great importance for DOC export due to the accumulation of soil organic matter and the often high groundwater level (Grabs et al., 2012; Inamdar & Mitchell, 2007; Ledesma et al., 2015; Ledesma, Kothawala, et al., 2018; Mei et al., 2014; Musolff et al., 2018; Ploum et al., 2020; Strohmeier et al., 2013). Therefore, hydrological connectivity between the riparian zone and streams has important implications for DOC export (Birkel et al., 2017; Bishop et al., 2004; Blaurock et al., 2021; Broder et al., 2017; Werner et al., 2021). Hydrological connectivity and, therefore, runoff and solute response to precipitation are dependent on the antecedent hydrological conditions in a catchment as well as individual event characteristics (Blaurock et al., 2021; Detty & McGuire, 2010; McGuire & McDonnell, 2010; Penna et al., 2015).…”
