Other Abstract

Supraglacial drainage system is one of the most important parts of glacial drainage systems, which impacts glacier surface ablation processes through transfer and drainage of surface meltwater. The existence of supraglacial drainage system also significantly impacts glacier flow and dynamics. Most of the conventional glacier hydrologic models suggest that surface meltwater can efficiently drain from glaciers and thus ignore the ability of supraglacial drainage system to retain meltwater. However, the impact of this retention, which leads to large uncertainties in glacier runoff prediction, could not be ignored. Therefore, it is crucial to improve the understanding in supraglacial drainage systems. The formation of supraglacial drainage system is controlled by glacier size,physical characteristics and ablation zone distribution. There is a seasonal development process of supraglacial drainage system from subsurface flow to slush flow and then to open channel flow. This dynamic supraglacial drainage system can route glacial surface meltwater into moulins, ice crevasses or supraglacial lakes through supraglacial networks with variable efficiencies and delays over space and time. In this paper, an attempt is tried to review the current supraglacial drainage system studies,and to discuss the evolution,distribution and constitution of supraglacial drainage system in sequence and their roles in meltwater transfer and drainage. In particular, hydrodynamics of supraglacial networks are discussed in detail to illustrate the pattern, efficiency and meltwater partition of supraglacial drainage system.
