Abstract. The Modified Fluid Loss test (MFL) was developed to measure hydraulic conductivity using the filter press method. Based upon modification of conventional filtration models, the average hydraulic conductivity of a bentonite filter cake can be obtained from the filtrate-time relationship and the water content of the filter cake. At higher effective stresses …
