What is the double ring infiltrometer test method?

The double ring infiltrometer test method was utilized to perform a total of four (4) infiltration tests on August 30, 2018 to evaluate near surface infiltration rates in order to estimate the amount of storm water runoff that can infiltrate into the onsite water quality treatment plan areas. The infiltration tests were

How do you measure infiltration rate?

Infiltration measurements Infiltration rate was measured using double-ring infiltrometers (Haise et al., 1956) and a drop-former type rainfall simulator (Roth et al., 1985 ). In the first case, readings were taken every 10 min, the water level subse- quently being returned to the 10-cm level.
