Getting the most out of your constant head permeameter
If you've actually had to calculate how quickly drinking water moves through a trial of coarse-grained ground, you've probably invested some good time with a constant head permeameter . It's one of those foundational tools in geotechnical engineering that will seems simple on the surface but requires a bit of a "feel" to get right. Unlike several of the more high-tech, digital-everything sensors we see in labs today, this particular setup relies upon basic physics and a steady hand to give a person reliable data about hydraulic conductivity. ...
