Abstract: The glaciers of the Hengduan Mountains play an important role in the hydrology processes of this region.In this study,the HBV Light model,which relies on a degree-day model to simulate glacier melting,was employed to simulate both glacier runoff and total runoff.The daily temperature and precipitation at the Hailuo Creek No.1 Glacier from 1952 to 2009 were obtained from daily meteorological observed data at the glacier and from six national meteorological stations near the Hailuo Creek Basin.The daily air temperature,precipitation,runoff depth,and monthly potential evaporation in 1995,1996,and 2002 were used to obtain a set of optimal parameters,and the annual total runoff and glacier runoff of the Hailuo Creek Glacier (1952-2009) were calculated using the HBV Light model.Results showed the average annual runoff in the Hailuo Creek Basin was 2,114 mm from 1952 to 2009,of which glacial melting accounted for about 1,078 mm.The river runoff in the Hailuo Creek catchment increased as a result of increased glacier runoff.Glacier runoff accounted for 51.1% of the Hailuo Creek stream flow in 1994 and increased to 72.6% in 2006.About 95% of the increased stream flow derived from the increased glacier runoff.
