Chamau

Site description

Chamau is located in a lowland broad river valley of the Reuss River. It is one of the three ETH research stations. Eddy covariance flux measurements were started at the end of 2005.

Landuse

Intensive management with six cuts per year (mainly for silage)

Soil & Geology

Cambisol
The area is located on tertiary molasse. The Reuss-valley is filled with postglacial retreating rubble («Rückzugsschottern»)of the Reuss glacier
