Dataset of observed streamflow and calculated base flow, groundwater runoff and groundwater discharge of the Zhizdra River, Russia (1958–2016)

This dataset accompanies the paper, titled “A physically based model of a two-pass digital filter for groundwater runoff separation from streamflow time series”, submitted to Water Resources Research. The dataset includes the daily river runoff of the Zhizdra River, Russia, during 1958–2016. Using this dataset, we validate the proposed two-pass digital filter model to separate groundwater runoff from streamflow. This dataset also includes the calculated base flow, groundwater runoff and groundwater discharge to the Zhizdra River, Russia, during 1958–2016.
