Geomorphic response to the lateglacial–holocene transition in high alpine regions (Sanetsch pass, Swiss alps)

Several palaeoclimatic archives have documented the pronounced climatic and environmental change associated with the Lateglacial–Holocene transition in the European Alps. However, the geomorphic response to this major environmental transition has only been punctually investigated. In this study, we propose a detailed reconstruction of post‐Last Glacial Maximum palaeoenvironmental...

Turbinage des eaux usées du Haut-Plateau de Crans-Montana

Musolla, Marie ; Münch-Alligné, Cécile (Dir.)

Mémoire de bachelor : Haute Ecole d'Ingénierie, 2019.

Le présent projet a pour but d’étudier la faisabilité et la rentabilité d’une centrale de turbinage sur le réseau des eaux usées du Haut-Plateau de Crans-Montana. Après avoir étudié l’état de l’art dans le domaine du turbinage des eaux usées et listé les installations existantes dans le monde avec les solutions technologiques installées, le potentiel hydraulique de ce...

The impact of climate change and glacier mass loss on the hydrology in the Mont-Blanc massif

The Mont-Blanc massif, being iconic with its large glaciers and peaks of over 4,000 m, will experience a sharp increase in summer temperatures during the twenty-first century. By 2100, the impact of climate change on the cryosphere and hydrosphere in the Alps is expected to lead to a decrease in annual river discharge. In this work, we modelled the twenty-first century evolution of runoff in...

Estimating glacier-bed overdeepenings as possible sites of future lakes in the de-glaciating Mont Blanc massif (Western European Alps)

Magnin, F. ; Haeberli, W. ; Linsbauer, Andreas ; Deline, P. ; Ravanel, L.

In: Geomorphology, 2020, vol. 350, p. 106913

De-glaciating high mountain areas result in new landscapes of bedrock and debris where permafrost can degrade, persist or even newly form in cases, and of new lakes in glacier bed overdeepenings (GBOs) becoming ice-free. These landscapes with new lakes in close neighborhood to over-steepened and perennially frozen slopes are prone to chain reaction processes (e.g. rock-ice avalanches into...

Little ice age glacier history of the central and western alps from pictorial documents

Zumbühl, Heinz J. ; Nussbaumer, Samuel U.

In: Cuadernos de Investigación Geográfica, 2018, vol. 44, no. 1, p. 115–136

The Lower Grindelwald Glacier (Bernese Oberland, Switzerland) consists of two parts, the Ischmeer in the east (disconnected) and the Bernese Fiescher Glacier in the west. During the Little Ice Age (LIA), the glacier terminated either in the area of the “Schopffelsen” (landmark rock terraces) or advanced at least six times (ten times if we include early findings) even further down into the...
