Progress in study of glacier hydrological model

The evaluation of the effects of glacier meltwater to Arid Area/regional water resources management,sea-level rising and glaciers natural disaster prevention are very important in the wake of global warming.This paper reviews the processes in glacier hydrological model in term of runoff generation model and runoff concentration rmdel,analyaes the runoff generation mode from two rmst widely ablation model (the meteorological factors statistical rmdel and the energy balance model),and enlarges on the runoff concentration model from three sub-models:the surface routing sub-model,the englacial hydrology submodel and the sub-glacial hydrology sub-rmdel.It is shown that the ablation model has become mature relatively,whereas the runoff concentration model is still at the exploration stage.The last part of this paper suggests the further research on constructing the distributed glacier hydrological physical models which suit to different scale and styles of glaciers and contain glacier movement information.
