Several years ago, CSSi started using permeameters and quickly discovered how useful and cost-effective they are for site assessments.
The field saturated hydraulic conductivity (Kfs) of soil is easily determined when using the permeameter. The stable rate of fall of water through the permeameter (in millimeters) when multiplied by the corresponding soil factor for the size of augered hole produces the Kfs value.
To make the translation of the data easier we calculated soil factors based on research by Mooers and Waller (1) that apply to CSSi permeameters and make the calculation of Kfs much easier.

Operating Instructions and Permeameter Log Sheets
Once you have purchased a permeameter, CSSi will email you a link that will allow you to print out the permeameter sheets and the permeameter summary form.
(In the past we include a CD with operation instructions and the appropriate log sheets)
CSSi sells two types of 3” augers that are made in Holland.
Regular soil auger: $169 + tax charged to your credit card, plus shipping collect.
Stoney soil auger: $199 + tax charged to your credit card, plus shipping collect.
Note: CSSi is looking for a larger diameter auger (4”), which would make it easier to use your hand to clean-out the bottom of the hole. If you have found such an auger, we would be pleased to hear about it.
When logging test pits, the coarse fraction should be separated from the sand/silt/clay fraction. This enables one to do a fairly quick and accurate assessment of the coarse fraction.
Screening greatly facilitates hand texturing, since small stones that interfere with casting and ribboning are not there.
Coarse fraction screen: $46.50 + tax charged to your credit card, plus shipping collect.
