Short summary

We investigate the impacts of anthropogenic water regulation on riverine DOC transport by the developed model. The results suggested that DOC transport in most rivers was mainly influenced by reservoir interception and surface water withdrawal. The impact of human water regulation on riverine DOC exports grew year by year. In general, this study developed an effective scheme to simulate DOC exports from terrestrial to aquatic systems, which is important for estimating global carbon budgets.
