Zusammenfassung
The hyporheic zone and the streambed host a great part of the energy and material fluxes through
river ecosystems. However, the role of heterogeneities in the hyporheic zone in metabolism is not
clearly understood. This paper proposes a new way to approach the question by using a coupled
subsurface-flow and metabolism model for investigating the role of heterogeneities in the hyporheic
metabolism. Our results show that (i) our coupled model is feasible for investigating solute fluxes in
the hyporheic zone under heterogeneous set-ups, and (ii) the incorporation of heterogeneities seems
be of relevance for hyporheic metabolism estimations
