      abstract     = {Subsurface and land surface processes (e.g. groundwater
                      flow, evapotranspiration) of the hydrological cycle are
                      connected via complex feedback mechanisms, which are
                      difficult to analyze and quantify. In this study, the
                      dual-boundary forcing concept that reveals space–time
                      coherence between groundwater dynamics and land surface
                      processes is evaluated. The underlying hypothesis is that a
                      simplified representation of groundwater dynamics may alter
                      the variability of land surface processes, which may
                      eventually affect the prognostic capability of a numerical
                      model. A coupled subsurface–land surface model ParFlow.CLM
                      is applied over the Rur catchment, Germany, and the mass and
                      energy fluxes of the coupled water and energy cycles are
                      simulated over three consecutive years considering three
                      different lower boundary conditions (dynamic, constant, and
                      free-drainage) based on groundwater dynamics to substantiate
                      the aforementioned hypothesis. Continuous wavelet transform
                      technique is applied to analyze scale-dependent variability
                      of the simulated mass and energy fluxes. The results show
                      clear differences in temporal variability of latent heat
                      flux simulated by the model configurations with different
                      lower boundary conditions at monthly to multi-month time
                      scales (~32–91 days) especially under soil moisture
                      limited conditions. The results also suggest that temporal
                      variability of latent heat flux is affected at even smaller
                      time scales (~1–3 days) if a simple gravity drainage
                      lower boundary condition is considered in the coupled model.
                      This study demonstrates the importance of a physically
                      consistent representation of groundwater dynamics in a
                      numerical model, which may be important to consider in local
                      weather prediction models and water resources assessments,
                      e.g. drought prediction},
