Groundwater Lab

Pressure Cells for Drainage Experiments:

• 15 pressure cells for parallel drainage
• pressure steps up to 1 bar
• automatic data acquisition of the drained water volume of each pressure cell separatelyt

Flume for 2D seepage experiments, unsaturated:

• size: 80 cm x 50 cm x 10 cm, pipe leak: 40 cm above bottom
• segmented bottom for differenciated outflow measurement
• holes in regular raster (10 cm x 8 cm) for installation of mirco tensiometers

Flume for 2D experiments, saturated:

• size: 3,17 cm x 1,25 m x 0,25 m, one side: vertical seperated filter screens (GCW), other side: complete filter screen (general flow)
• front: glas front
• backside: high density of sampling points in the area of the ciculation flow

Columns for 1D-experiments:    

• 3 stainless steel + 1 glass column (d = 10,8 cm, L = 50,0 cm)
• sampling points in 4 different levels and several azimut angles
• connection to closed water system
