Our laboratory studies about transfer of water and energy between the land surface and the lower atmosphere. It involves the measurement, analysis and modelling of atmospheric and land surface processes tied to the hydrologic cycle. These analyses often serve as the bases for the design of flood-control and water-usage structures, primarily dams and reservoirs. Furthermore, our laboratory carries out studies on rainfall probabilities, the space and time distribution of rainfall and evaporation, the recurrence interval of major storms, snow melt and runoff. Water movement in soil is also a very popular research area of our laboratory.
