A hydrologist's guide to open science

Open, accessible, reusable, and reproducible hydrologic research can have a significant positive impact on the scientific community and broader society. While more individuals and organizations within the hydrology community are embracing open science practices, technical (e.g., limited coding experience), resource (e.g., open access fees), and social (e.g., fear of weaknesses being exposed or ideas being scooped) challenges remain. Furthermore, there are a growing number of constantly evolving open science tools, resources, and initiatives that can be overwhelming. These challenges and the ever-evolving nature of the open science landscape may seem insurmountable for hydrologists interested in pursuing open science. Therefore, we propose the general Open Hydrology Principles to guide individual and community progress toward open science for research and education and the Open Hydrology Practical Guide to improve the accessibility of currently available tools and approaches. We aim to inform and empower hydrologists as they transition to open, accessible, reusable, and reproducible research. We discuss the benefits as well as common open science challenges and how hydrologists can overcome them. The Open Hydrology Principles and Open Hydrology Practical Guide reflect our knowledge of the current state of open hydrology; we recognize that recommendations and suggestions will evolve and expand with emerging open science infrastructures, workflows, and research experiences. Therefore, we encourage hydrologists all over the globe to join in and help advance open science by contributing to the living version of this document and by sharing open hydrology resources in the community-supported repository (https://open-hydrology.github.io, last access: 1 February 2022).

Automated summary

Open, accessible, reusable, and reproducible hydrologic research has significant positive impact. Challenges such as limited coding experience and fear of weaknesses being exposed hinder the adoption of open science practices in the hydrology community. To address these challenges, the Open Hydrology Principles and Open Hydrology Practical Guide are proposed to guide individual and community progress. Hydrologists are encouraged to contribute to the living document and share resources in the community-supported repository.
