The question of model conditions (i.e., saturation procedure and temporal dewatering of soil model, as well as existence of a geotextile on the top of seabed model and existence of pore-pressure transducers itself in seabed sediments) in large-scale modelling is discussed with respect to the quality of measured pore-pressure values. The meaning of locally unsaturated zones within the seabed model, due to an improper installation procedure or man-made mistake during the testing period, are illustrated by some example computations, based on 2-D finite-element model, the results of which are presented in terms of the momentaneous pore-pressure distribution with depth, induced by surface harmonic waves passing over the seabed.
