Geometry, bed topography and drainage system structure of the Haut Glacier d'Arolla, Switzerland
As part of an integrated study of the hydrology, meltwater quality and dynamics of the Haut Glacier d'Arolla, the glacier's drainage network structure was determined from patterns of dye recovery in 342 injection experiments conducted from 47
Temporal switching between englacial and subgacial drainage pathways: dye tracer evidence from the Haut Glacier d'Arolla, Switzerland
34 dye tracing experiments conducted from a moulin, located 1.5 km from the snout of the Haut Glacier d'Arolla, during the summer of 1989-1991 reveal 2 distinct drainage paths between the moulin and the glacier snout.
Recherches effectuées sur 6 moraines médianes de glaciers près d'Arolla, Valais, Suisse. Elles sont toutes nourries par la moraine interne, les matériaux provenant de sources supraglaciaires dans la zone d'accumulation des glaciers. La formation de
ces moraines est étudiée. Quatre types de moraines (distingués d'après la nature de leurs matériaux et le détail de leur morphologie) sont identifiés dans le secteur d'Arolla et peuvent servir de base pour une classification des moraines médianes.
An analysis of short-term albedo variations at Haut Glacier d'Arolla, Switzerland
An analysis of ten-minute albedo variations, recorded on Haut Glacier d'Arolla, over an 11 day period in the 1999 ablation season is presented. Most of the short-term (
Channel change in relation to meltwater flooding, Bas Glacier d'Arolla, Switzerland
Meltwater flooding in the valley train of the Bas Glacier d'Arolla, (1986 and 1987) produced significant changes in channel form. The general channel response involved switching from a single thread, low sinuosity stream to a wider channel
Seasonal changes in the morphology of the subglacial drainage system, Haut Glacier d'Arolla, Switzerland
Dye tracing techniques were used to investigate the glacier-wide pattern of change in the englacial/subglacial drainage system of Haut Glacier d'Arolla during the ablation seasons of 1990 and 1991. In both years, the tracer injection programme began
Basal sediment evacuation by subglacial meltwater : suspended sediment transport form Haut Glacier d'Arolla, Switzerland
Proglacial suspended sediment transport was monitored at Haut Glacier d'Arolla, during the 1998 melt season to investigate the mechanisms of basal sediment evacuation by subglacial meltwater. The AA. use regression analyses to rigorously constrain
Genèse des moraines médianes: étude des cas du Kaskawulsh Glacier (Yukon) et de Tsidjiore Nouve (Arolla, Suisse). Les bandes de débris semblent provenir d'une ingestion par les crevasses et d'une restitution à la base du glacier, d'après les

Mesures de géométrie hydraulique d'un chenal supra-glaciaire pérenne sur la surface du glacier d'Arolla dans le Val d'Hérens. Les données indiquent une similitude morphologique avec les ajustements hydrauliques caractéristiques des rivières
Diurnal fluctuations in glacier ice deformation : Haut Glacier d'Arolla, Switzerland
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
This paper explores patterns within and between climatological and hydrological time series from an alpine glacier basin. Time series recorded in the basin of the Haut Glacier d'Arolla over the 1989 ablation season are subdivided into five
This work investigates the interplay between fluids and metamorphic recrystallisation in the Austroalpine Dent Blanche Nappe (Western Alps, Italy). This nappe consists of the Arolla and Valpelline Units, respectively dominated by metagranitoids
With the purpose of improving the ice physics underpinning time-dependent glacier flowline models, 3 independent approaches for solving longitudinal stresses in glaciers are discussed and verified by application to Haut Glacier d'Arolla
The development of medial moraine on the Glacier de Tsidjiore Nouve is related to numerous englacial debris layers of limited dimensions, which are exposed at the glacier surface below the Pigne d'Arolla ice fall. The morphology of the debris layers
