      abstract     = {Riparian zones as the transition zone between terrestrial
                      and aquatic ecosystems play an important role in C and N
                      cycling and greenhouse gas (GHG) emissions. As such, they
                      may help to mitigate climate change but could also
                      accelerate it, depending on the particular processes
                      affected by changes in the hydrologic regime. Hydrological
                      observations indicated frequent shallow groundwater in the
                      riparian zone, especially near the stream and during the wet
                      winter and spring seasons with consequently frequent
                      occurrence of soil water saturation. The redox potential was
                      mainly governed by the soil water regime: under water
                      saturation conditions, the redox potential of the soil
                      decreased and returned to the oxic state after soil
                      drainage. We found that soil temperature and soil water
                      content were the main drivers of the variations in CO2
                      fluxes, with highest CO2 emission during summer and the
                      lowest emissions in the winter period (162.2–5.4 mg
                      CO2–C m−2 h−1). The annual average daily N2O emission
                      rate was low (2.3 μg N2O-N m−2 h−1), with the highest
                      average daily N2O emission in March as a result of low
                      temperature and partial soil saturation after heavy
                      precipitation events (37.5 μg N2O-N m−2 h−1). Our study
                      showed that continuous measurement of redox potential, soil
                      temperature, and soil water content can improve the
                      understanding of GHG emissions in riparian zones.},
