  bibo_abstract:
  - The topography of a landscape regulates the spatial distribution of water and
    energy fluxes, which are main drivers of vegetation and soil carbon and nutrient
    dynamics. Despite the recognized role of topography in mediating such processes,
    quantifying and predicting the spatial distribution of carbon and nutrient fluxes
    and stocks in highly heterogeneous landscapes remains challenging. The main limitations
    stem from the prevalence of largely decoupled modeling approaches which fail to
    concurrently account for ecohydrological and biogeochemical processes as well
    as the lack of adequate frameworks describing the links among topography, water
    and energy balances, and soil biogeochemical dynamics. Here, we extend the capabilities
    of the mechanistic ecohydrological model Tethys-Chloris-Biogeochemistry (T&C-BG)
    by including a soil carbon and nutrient routing module in the distributed model
    version. The newly developed T&C-BG-2D model is validated against long-term hydrological
    and biogeochemical measurements from the Hafren catchment in Wales (UK) and the
    Erlenbach catchment in the Swiss pre-Alps. The model successfully captures carbon
    and nutrient concentrations and dynamics in these catchments, with relative differences
    between simulated and observed median values of between −4% and −0.3% for dissolved
    organic carbon, and between 1% and 20% for ammonia. A sensitivity analysis in
    the Erlenbach basin suggests that elevation explains over 80% of the observed
    spatial patterns, followed by topographic wetness index (12.6%), aspect (2.9%),
    and curvature (2.1%). These findings underscore topography's critical role in
    shaping water, carbon, and nutrient dynamics, which cannot be reflected in plot-scale
    simulations neglecting spatial interactions and topographic effects.@eng
