Description :
Measurements of surface velocity, ice deformation and proglacial stream discharge were made at Haut Glacier d'Arolla to determine diurnal patterns of variation in each. The aim of this paper is to develop a better understanding of high frequency hydrological and dynamic processes by determining whether relationships between hydrology, internal ice deformation and glacier surface motion can be distinguished at diurnal timescales. Such processes may play a critical role in the development of three-dimensional patterns of temperate glacier flow when integrated over longer timescales.
