O článku:
Soil hydraulic conductivity is a key parameter to predict water flow through the soil profile. We have developed
an automatic minidisk infiltrometer (AMI) to enable easy measurement of unsaturated hydraulic conductivity using
the tension infiltrometer method in the field. AMI senses the cumulative infiltration by recording change in buoyancy
force acting on a vertical solid bar fixed in the reservoir tube of the infiltrometer. Performance of the instrument was
tested in the laboratory and in two contrasting catchments at three sites with different land use. Hydraulic conductivities
determined using AMI were compared with earlier manually taken readings. The results of laboratory testing demonstrated
high accuracy and robustness of the AMI measurement. Field testing of AMI proved the suitability of the instrument
for use in the determination of sorptivity and near saturated hydraulic conductivity.
