Hydrology and Earth System Sciences (HESS) is a not-for-profit international two-stage open-access journal for the publication of original research in hydrology. HESS encourages and supports fundamental and applied research that advances the understanding of hydrological systems, their role in providing water for ecosystems and society, and the role of the water cycle in the functioning of the Earth system. A multi-disciplinary approach is encouraged that broadens the hydrological perspective and the advancement of hydrological science through integration with other cognate sciences and cross-fertilization across disciplinary boundaries.
Journal metrics
HESS is indexed in the Web of Science, Scopus, Google Scholar, etc. We refrain from displaying the journal metrics prominently on the landing page since citation metrics used in isolation do not describe importance, impact, or quality of a journal. However, these metrics can be found on the journal metrics page.

Temporary unavailability of article and preprint PDFs due to technical issues
Since Tuesday, 5 May, 06:30 CET, we have been experiencing technical issues caused by high demand on our systems, which have significantly affected our journal libraries. To maintain platform stability and ensure continued access to critical services, all preprint and journal article PDFs were temporarily restricted, while HTML full-text content and XML files remained available. Since Thursday, 7 May, 08:30 CET, we have made the preprint PDFs available again; however, journal article PDFs remain restricted until the technical issues have been resolved. We apologize for the inconvenience and appreciate your patience as we work to restore full PDF access as quickly as possible. Thank you for your understanding.
