Practical Experience with the Modified Philip–Dunne Infiltrometer Test

June 2023 | Rob Sowby, Dan Jones, and Kayson Shurtz

The modified Philip–Dunne (MPD) infiltrometer test has been promoted as an efficient option for field measurement if hydraulic conductivity, particularly in rain gardens and other green stormwater infrastructure. However, the literature misses some details on its performance in practice. Based on our experiences building our own equipment, executing the test in various field conditions, and determining hydraulic conductivity for the purposes of engineering design, we describe some limitations for other users to consider and improve upon.
