摘要
Groundwater is a dynamic, finite, and vulnerable but resilient natural resource to be protected in an environmentally sustainable manner. Groundwater systems require a comprehensive understanding of climatology, geology, morphotectonics, hydrogeology, hydrogeochemistry, hydrodynamics, isotope hydrology, hydrogeomorhology, rock and soil hydrogeotechnics, and surface hydrology. Groundwater conceptual models (ground model, hydrogeological conceptual model, and numerical model)—from site investigations to regional watersheds and or global hydrological systems—based on earth systems make a major contribution to the sustainability and management of water resources. The thematic issue on “sustainability and water resources-includes a wide variety of unique contributions in environmental hydrogeology and water-related research and practice.
