mini disk infiltrometer
unsaturated hydraulic conductivity
- A low cost, portable infiltrometer for soil science researchers
- Accurately measure unsaturated hydraulic conductivity and infiltration rates on a range of soils
- Low volume of water makes the mini disk infiltrometer ideal for remote field sites
- Free Excel macro worksheet to assist with unsaturated hydraulic conductivity calculations
Water movement in soil is spatially variable. The Mini Disk Infiltrometer is a quick way to test unsaturated hydraulic conductivity and infiltration rates.
Small, and simple, the Mini Disk Infiltrometer is a true field instrument. It can be tossed into a backpack with a bottle of water. Adjustable suction and a porous stainless steel contact plate assure a reliable soil unsaturated hydraulic conductivity measurement.
Just fill the reservoir, set the suction, and start measuring infiltration. You don't have to pre-saturate the disk.
Enter the infiltration and elapsed time data in the included spreadsheet calculator to find unsaturated hydraulic conductivity.
Both scientists and technicians have used the Mini Disk Infiltrometer to design irrigation systems, demonstrate hydraulic conductivity, evaluate erosion hazard, and gauge the impact of forest fires. It's ideal for irrigation system design, classroom instruction, erosion hazard evaluation, burn severity studies, and many other applications.
