The Concept of Accuracy Analysis of the Vertical Displacements Gained from the Hydrostatic Levelling Systems' Measurements.

Nowadays, hydrostatic levelling is a widely used method for the vertical displacements' determinations of objects such as bridges, viaducts, wharfs, tunnels, high buildings, historical buildings, special engineering objects (e.g., synchrotron), sports and entertainment halls.

Estimation and Prediction of Vertical Deformations of Random Surfaces, Applying the Total Least Squares Collocation Method.

This paper proposes a method for determining the vertical deformations treated as random fields. It is assumed that the monitored surfaces are subject not only to deterministic deformations, but also to random fluctuations. Furthermore, the existence of random noise coming from surface's vibrations is also assumed.
