Comparison of three measurement methods of saturated hydraulic condutivity

After pointing out the importance of the saturated hydraulic conductivity (k s ) measurements and the di culties and uncertainties that are present, and after recalling salient aspects of three well-known measurement methods of this parameter (i.e. constant-head tension infiltrometer (TI) method, constant-head pressure infiltrom5 eter (PI) method and soil core (SC) estimates method), the results of an investigation on data which were obtained during a measurement campaign on an area of 800m 2 , on a sandy loam hillslope, located in Southern Italy, were carried out again here. Three sets of values of ks , obtained with these measurement methods, were analyzed statistically, verifying that the log-normal distribution describes these better than the normal 10
