The hydrological cycles and material transports involving the effects of climate changes and human impacts on the earth surface, an important aspect of environmental science and human life, has not yet been fully depicted. New recent observations performed in regional scales have revealed changes on the earth surface systems that should be more deeply investigated by a multidisciplinary approach in multiple spatiotemporal scales as providing important base for developing sustainable and well-being society. Our research group investigates these issues on near-surface environments including atmosphere, watershed, aquifers, and costal environments on regional to global scale, using various physicochemical parameters, isotopes, simulation tools, AI approaches and big data. Effects of natural disasters on earth systems including floods, earthquakes and volcanic eruptions are also major concerns of this research unit.
