Abstract

Glacier motion, retreat, and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that lead to changes in ice mass balance in High Mountain Asia (HMA). We present the first application of the Subglacial Hydrology And Kinetic, Transient Interactions (SHAKTI) model on an alpine glacier. Shishper Glacier, our study site, is a mountain glacier in northern Pakistan that exhibits concurrent surges and GLOFs which endanger local communities and infrastructure. Without coupling to...  more
