Field Saturated Hydraulic Conductivity

Automated measurement - Simplified data analysis


Get more out of every field visit.

Saturated hydraulic conductivity is a pain to measure in the field. And the field measurement is only the beginning. When you get back to the office, you need to convert the raw data into hydraulic conductivity and infiltration rates.

We think you should spend less time on complex measurement processes and more time being productive. That’s why we automated almost everything in the new SATURO.

Set it up, and leave.

The SATURO Infiltrometer does almost everything for you. It’s fully automated and doesn’t require post-processing of data. Install the ring, connect the hoses, and push “start”.  It’s that simple.

The infiltrometer automatically measures infiltration rates, and the control unit calculates saturated hydraulic conductivity (Kfs) on the fly. That means if you need a value right away, it’s there. If you want to dig deeper, you can always download the raw data.

One person can do everything.

Unlike double ring systems, the SATURO is designed for one person to carry and set up. And, you can run multiple instruments simultaneously, allowing you to maximize the efficiency of your time in the field.

Eliminate guessing.

Water flows through soil in three dimensions. In the early days, it was difficult to solve three-dimensional equations. Infiltrometers were created to try and force water to flow in one dimension and required the use of estimated parameters to get reasonable hydraulic conductivity values.

Thanks to some mathematical magic, single ring measurements are now possible, making the whole process simpler and more efficient. The best part is, you don’t have to rely on any dubious assumptions. 

A simple, precise solution.

The SATURO combines automation and simplified data analysis together in one system. It even computes infiltration rates and saturated hydraulic conductivity on the fly. The SATURO makes life a little easier for those who need a faster, more accurate way to measure Kfs in the field.

The range of Kfs values that can be effectively measured by the DualHead Infiltrometer are limited by the minimum and maximum infiltration rates specified above. These depend not only on Kfs, but also on the pressure heads applied to the water during infiltration and to the 3-dimensional flow characteristics of the soil, so the measurement range of Kfs cannot be specified explicitly. The DualHead Infiltrometer will generally be able to make measurements on poorly to moderately structured soils as coarse as medium sand, but the maximum infiltration rate can be exceeded by soils with excessive structure and especially by soils with significant macropore flow.
