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.
