The Chinese National Committee of IAHS is glad to provide the national report from 1999 to 2002 on hydrological science to the members of IUGG. The main developments in hydrological science contributed by Chinese scientists in the past four years are included in this report. It involves the following aspects: hydrological cycle and surface water, groundwater, land erosion, snow and ice, water quality, water resources system, application of RS in the management of hydrology and water resources, soil-vegetation-atmosphere system in hydrological process, and application of isotope technique in the management and assessment of hydrology and water resources etc.
