  Experimental equipment
  • At Col du Lac Blanc there are two types of experiment taking place as part of SATSIE. The first involves the use of a large (0.5 metres cubed) rheometer for studying the behaviour of snow that is subjected to shear.

  • In addition, a chute will be used to obtain measurements of the stresses, flow depth, density and velocity gradient of flowing snow. The intention is to produce laws that relate the stresses to the velocity gradients and snow flux to the flow depth and angle of the chute. The chute was installed in March 2001. It consists of a hopper (5 metres cubed volume) from which the snow is transported to a 10 m long chute at a constant rate using an Archimedes screw.
