The Journal of Hydrology and Hydromechanics is an international, open-access journal for the basic disciplines of water sciences.The scope of hydrology is limited to biohydrology, catchment hydrology, and vadose zone hydrology, primarily of the temperate zone. Submitted papers should be original research papers that enhance the science in the above-mentioned parts of hydrology.The hydromechanics covers theoretical, experimental and computational hydraulics and fluid mechanics in various fields, two- and multiphase flows, including non-Newtonian flow, and new frontiers in hydraulics.The Journal publishes original research papers, case studies, and reviews that have been thoroughly peer reviewed. The submitted papers aimed at region-specific problems, should present and analyse past and/or future conditions and design solutions, or provide new knowledge or results compared to other previously published studies (comparative science). Novelty of the contribution should be clearly presented. The journal particularly welcomes research papers that deliver new insights into region-specific hydrological or hydrodynamic processes and responses to changing conditions.The authors are not subject to any publication fees.The Journal is published by the Institute of Hydrology of the Slovak Academy of Sciences, Bratislava, Slovak Republic. Volumes 1–40 of this journal were issued under the title Vodohospodársky časopis.
