Porchet method equation
WebInfiltration tests are carried out to estimate K fs in natural soils, where constant head well permeameter method and tension infiltrometer method show similar results, whereas … WebIt was determined that the saturated Porchet method is more difficult and time-consuming than the ordinary Porchet method. Therefore, a relationship between these two tests has been developed in the study area [similar to the equation that was presented by Sepaskhah and Rezaee (1998)] and estimation of K s from ordinary Porchet method can then be …
