How to publish in this journal


Hydrology (ISSN 2306-5338) is an international, multi/interdisciplinary open access and peer-reviewed journal that focuses on hydrological sciences. The journal encompasses all aspects of hydrology: groundwater, surface water, soil water, and atmospheric water, as well as snow and ice. Papers advancing the quantitative, qualitative, ecological, and managerial aspects of hydrology are welcome. Particularly welcome are those papers that discuss such aspects’ interrelationships. Research addressing issues in integrated water management, policy, and socio-hydrology are also invited. We encourage colleagues to submit their original theoretical, field, experimental, and numerical studies and literature reviews and especially look forward to multidisciplinary approaches and interdisciplinary topics, which cross the typical boundaries of our science. Themes encompassed in Hydrology include: Surface water hydrology, Groundwater hydrology, Vadose zone hydrology, Ecohydrology, Hydrochemistry, Hydroinformatics, Hydrometeorology, Isotope hydrology, Water management, Socio-hydrology, Water quality Join the conversation about this journal

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Total Documents

Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
