Dear Researchers,
I am finding standards for in-situ hydraulic conductivity test. As I know that there are two field tests, namely, single ring and double ring test.
I am wondering if you could tell me other methods/ standards?
Thank you very much for your consideration,
Kindly regards,
Nguyen Trung Kien
Dear Kien Nguyen,
The following information may help you.
In Situ Hydraulic Conductivity Tests:
(1) The Boutwell permeameter; (2) constant‐head borehole permeameters, e.g., the Guelph permeameter; (3) porous probes, e.g., the BAT device; (4) open, single‐ring infiltrometers; (5) open, double‐ring infiltrometers; (6) closed, single‐ring infiltrometers, (7) sealed, double‐ring infiltrometers; (8) the air‐entry permeameter; and (9) lysimeter pans

In addition, you can evaluate in-situ permeability from the following tests:
- Piezocone Penetration (CPTu).
- Soakaway test in the test pit
All the best.
There are some in-situ permeability tests of soil, small and large-scale field tests. among in-situ tests; single ring and double ring test methods are suitable for surface soil (almost Kv in small scale), and Lefranc and Pumping tests methods are suitable for deep soil (Kh and Kv). for more information, see the following link
