  text: A spatially distributed trace metal transport and transformation module was
    developed and implemented within the hydrological model TOPKAPI-ETH. The new module
    can be used to better understand, at high spatial and temporal resolution, the
    transport and reactions of trace metals as they move through a catchment from
    upland sources to downstream areas and water bodies. The newly developed module
    takes into consideration solid metal in multiple chemical phases with different
    reactivity and simulates their mutual transformation over time, which gives the
    possibility to analyze the fraction of different solid metal phases present in
    the river suspended sediment. The characteristics and potential of the model are
    demonstrated by simulating Zinc (Zn) and Cadmium (Cd) dynamics in a headwater
    catchment of the Xiang River in South China, which has been highly perturbed by
    mining activities. The developed module is shown to reasonably reproduce the observed
    dynamics of dissolved and total trace metals flux for 14 months at two monitoring
    stations. The distributed solute transport model was proved to be capable of explaining
    the reasons underlying the spatial variability of C-Q relationships that are driven
    by the combined effect of point and non-point pollution sources, as well as identifying
    the spatiotemporal hotspots of trace metal pollution. By means of synthetic numerical
    experiments, a limited impact of slow reactions on dissolved Cd transport from
    upland to river over short-temporal scales was demonstrated, while for longer
    scales, e.g. >5 years, this effect becomes more relevant, highlighting potential
    long-lasting sources of trace metal pollution and their impacts.
