在估计碎片覆盖的冰的融化量时，没有考虑到雨的热通量，尽管在尼泊尔喜马拉雅山的融化季节有很多雨。1996年7月15日至8月29日，利用蒸渗仪对尼泊尔喜马拉雅山利荣冰川（Lirung Glacier）的一个冰川融化季节的蒸发量进行了测量。观测结果表明，25%的总降雨量蒸发的碎片覆盖的冰川。尽管蒸发水占总降雨量的75%，但蒸发水的热通量对碎片下的冰融化所需的热量没有影响。
Heat flux with rain has not been taken into account in estimating melt amounts of debris-covered ice, although there was a lot of rain during the melting season in the Nepal Himalayas. Some of the rain falling on the debris-covered glacier will evaporate, and the rest will percolate through the debris layer and will supply heat to melt the ice beneath it. Evaporation amounts during a melting season from 15 July to 29 August in 1996 were measured using a lysimeter on a debris-covered area of Lirung Glacier, Nepal Himalayas. Observational results indicated that 25% of the total rainfall evaporated at that debris-covered glacier. The heat flux with percolated water has no effect on the heat needed to melt ice under the debris, although percolated water accounts for as much as 75% of the total rain amount.
