Hydraulic conductivity test kit

09.01

The standard Hydraulic conductivity test set is suitable for measurements to a depth of 6.6 feet (2 meter). The Hooghoudt variant goes up to 16.4 feet (5 meter). The complete set can be transported in the field in a strong carrying bag.

  • Infiltration and soil permeability research
  • Ideal tool to determine drain spacings
  • Perfect for K-values below groundwater table
  • Perforated casing can be extended

Description

Method

When measuring hydraulic conductivity of soil, the auger hole method according to Hooghoudt can be applied for direct measurement in the field. With this method, the permeability of soil can be determined relatively fast and with a limited number of instruments.

The principle of this method is quite simple: a hole is bored in the ground to a certain depth below the groundwater level. After some time, the hole will fill with water up to said water level. This water is consequently bailed out. The time it takes for a new water level to establish itself is recorded. Using formulas and/or nomograms, this speed with which the water rises can be translated into the average permeability factor of the various soil layers.

The depth of the bore hole is dependent upon the groundwater level and the thickness and the permeability of the successive layers in the ground profile.

Product variants

The standard set (09.01.SA) is suitable for measurements to a depth of 6.6 feet (2 meter). For measurements to a depth of 16.4 feet (5 meter) there is the Hydraulic conductivity test kit, Hooghoudt set (09.01.SB). This set includes the same items as the standard set; however, the 1-meter-long filter has been replaced by an extendable filter with a total length up to 16.4 feet (5 meter) (also including extension rods for the auger).
