Hydrogeology Journal has acquired a large worldwide readership since its inception in 1992. The Journal's emphasis is to:/// Foster understanding of hydrogeology, a practical discipline aimed at bettering the human situation on earth,
/// Describe worldwide progress in hydrogeology,
/// And to provide an inexpensive and widely accessible forum for scientists, researchers, engineers, and practitioners in developing and industrialized countries alike.
A mainstream paper in Hydrogeology Journal integrates subsurface hydrology and geology with the other supporting disciplines (such as geochemistry, geophysics, geomorphology, geobiology, surface-water hydrology, tectonics, mathematics, numerical modeling, economics, and sociology) to explain phenomena observed in the field. Hydrogeology Journal publishes peer-reviewed papers in both theoretical and applied aspects of hydrogeologic science, including:
/// Theoretical and field studies ranging in scale from local areas and short time periods to regional or global problems and geologic time,
/// Techniques and innovative instrumentation in the laboratory and field (for example, hydrologic, geochemical, geophysical, and mathematical),
/// Water-resource and related mineral-resource evaluations,
/// Reports of observed hydrogeologic phenomena,
/// Overviews of hydrogeologic systems of interest in various regions,
/// State-of-the-art-reviews,
/// Philosophy of scientific methods in hydrogeology,
/// Interaction between populations and hydrogeologic systems,
/// Economics of hydrogeologic systems,
/// Ramifications of hydrogeology on both environmental protection and optimal employment of natural resources,
/// And the history of hydrogeology and biographies of eminent hydrogeologists.
