This laboratory has most of the standard instruments to characterise the hydraulic properties of about a hundred soil samples at the same time.
For the retention curve, the following equipment is available:
two sandboxes to characterise the retention curve of about 90 soil samples from pF 0 to pF 1.8.
six pressure plate extractors for the retention curve between pF 2 and 4.2.
a water potential analyser for high pF by psychrometry (WP4C).
a 10 cell HYPROP system (evaporation method) for 250 cm³ soil samples.
For the hydraulic conductivity curve:
a permeameter for the saturated hydraulic conductivity. (Closed system - 10 holders)
the HYPROP system.
Measurements performed in the laboratory are invoiced in order to be able to amortize the cost of the equipment. Here is a document describing the pricing in detail : Soil physical properties characterisation - Price List.pdf.
In addition, the laboratory has several instruments for in situ measurements: pressure & suction infiltrometers, TDR probes, tensiometers, etc. and equipment for soil sampling (Rings of 100, 250, 1000 cm³).
You can find here the available soil sampling material: Physique du sol - Equipements.xlsx.
It can be found at B.230 (De Serres building). For any information or request for use, please contact Arnaud Willems (or Sébastien François).
