Calculation parameters were defined to obtain the experimental semivariograms of the survey grid both globally and for the test slab (Table 8). The anisotropy of the study area was analyzed considering different azimuth values in the xy-plane and in vertical direction (the z-axis). “Lag separa...
In the vertical direction, the 2.5 cm “lag separation” defined for the 𝑞𝑑qd values produces a virtually continuous experimental semivariogram that facilitates fitting the theoretical model for the full survey grid and each test slab. A Different spherical models are found to fit all the exp...
