The Hydram Laboratory fixed some 20 years ago
its priorities in terms of water research. In the aim of studying
and modelling the hydrological processes, the Haute-Mentue basin
has been chosen as the experimental catchment of the laboratory.
This catchment forms the upper part of the Mentue basin which
is monitored by the Swiss National Hydrological and Geological
Service. The characteristics below concern only the Haute-Mentue
Research catchment history
1975: The Swiss National Hydrological and Geological
Service installed the Dommartin flow gage.
1987: 4 new rain gages have been installed
at Chardonney, Villars-Tiercelin, Froideville and Chalet de
1988: The catchment is under the responsability
of the Hydrology and Land Improvement Laboratory; Several flow
gages are operational: Corbassière, Corbamont, Alloux,
Orsoud, GrandBois 1 et 2.
1992-1993: The measurement setup has been completed
with new flow gages: Bois-Vuacoz, Ruzillon and Esserts and a
meteorological station at Chalet de Villars.
1992-2004: Different other temporary equipement
has been installed (piezometers, TDR, rainfall simulator, 3D
electrical resistivity tomography) in the frame of several PhD
researches (see Instruments).
The Haute-Mentue experimental catchment is
located in the west part of Switzerland, 15 km north of Lausanne,
in the canton of Vaud. This catchment belongs to the Swiss Plateau,
which lies between the Jura (at west) and the Alps mountains
