Stable isotope (δ18O, δ2H) signature of river runoff, groundwater and precipitation in three river basins in the center of East European Plain
Abstract. Empirical study of the isotopic features of river runoff were carried out at three hydrological posts in 3 different river basins: the Zakza river in the center of East European Plane (southwest of the Moscow), the Dubna river (north of the Moscow) and the Sosna river in the south of central region. Samples of river water, groundwater and precipitation for the October 2019–October 2021 were collected at weekly intervals. A significant supply of melted snow during spring freshet is the key factor influencing water regimes for these three river basins; varying degrees of anthropogenic flow regulation are also present. During the observation period, there were fundamentally two completely different conditions in terms of runoff formation. First, October 2019–October 2020, there was abnormal low spring freshet instead there was high rain flood in summer. In October 2020–October 2021 there was a normal intra-annual flow pattern with high spring freshet. The new data of stable isotope signature of river runoff component can help to study the response of a river runoff to changing climate conditions.

We are very grateful to the Reviewer for comments and suggestions. We have made some correction to ‘Abstract’ and ‘Introduction’ sections to show the importance, relevance and completeness of our data. Also, the manuscript was read and corrected by native English speaker. All minor remarks corrected.
In the attached pdf file we provide our replies in a point-by-point manner with the responses given in blue and the comments of Reviewer given in italic black.

Chizova et la present an extensive dataset of O and H stable isotope ratios in precipitation, ground and surface (river) waters from the East European Plains in Russia. This is most welcome for the wider stable isotope, hydrology and paleoclimate scientific communities as it would help expand the spatial and temporal coverage of existing datasets towards region that is poorly covered by such data. I suggest publication of the ms and associated data. A few minor comments and one major concern should be nevertheless addressed:
- The extremely low intercept of the Sosna LMWL suggest something is (potentially) wrong with the data. Checking it at the link provided by the authors (Pangaea) shows several months (1/3 of the data points) with very to extremely low d-excess values (as low as -32 ‰). The samples have been collected mostly in summer, but some are also from April and May. While sub-cloud evaporation could cause low d-excess, the values reported here are too low, hinting at post-deposition processes (e.g., improper handling of samples after collection) and/or problems during analysis (e.g., contamination with volatile organics, a problem that would affect samples analyzed using CRDS systems – as done by the authors – contrary to analyses performed using IRMS analyzers). Some of the precipitation samples collected at Zakza and Dubna also display low (negative) d-excess values, but within the “normal” range of samples affected by post-depositional evaporation. As groundwater and river samples do not show similarly extreme d-excess values, I believe the issue stems from improper handling of the samples collected at Sosna. Please check (and if samples are still available) re-run them on an IRMS. Else, a cautionary note should be inserted in the main text of the manuscript.
- To make full usage of the data, precipitation amount and air temperature data should be made available.
- A note on nomenclature. Please check the ms for improper usage of stable isotope jargon (e.g., “stable water isotopes” – water has no stable isotopes per se, only oxygen and hydrogen in water have etc)
- Sentence structure and grammar: please check (overall) the structure of sentences, to often these are very long so that by the end of a sentence the reader loses the information at the beginning

We thank Dr. Aurel Perşoiu for comments and suggestions. The text has been edited. Also, the manuscript was read and corrected by native English speaker. We added a new data on precipitation amount and air temperature, weighted by precipitation amount to our dataset, it could be access via https://doi.org/10.1594/PANGAEA.948718
