While the discipline reflects on ways of dealing with this challenge, we recommend that, in the interim, multiauthored research papers should include a statement of attribution of contributions, specifying who of the author list contributed in designing the research, conducting the research, writing the text, editing the text, and funding the research. Most hydrology journals have therefore adopted a policy of open data and open models (e.g., Data Citation Synthesis Group 2014) to allow peers-at least in principle-to repeat any published study. Open data/model policies will certainly need particular attention in the near future and will likely require a change in the thinking of researchers and data collection agencies. A comparison among six leading hydrology journals over the period from 1996 to 2016, published as an editorial in Water Resources Research (WRR; Clark and Hanson 2017), concludes that the journal impact factor in a given year does not have much predictive power for journal-level productivity.
