Inclinometers are used to monitor subsurface movements and deformations. Typical applications include:

-Detecting zones of movement and establish whether movement is constant, accelerating, or responding to remedial measures.

-Checking that deformations are within design limits, that struts and anchors are performing as expected, and that adjacent buildings are not affected   by ground movements.

-Verifying stability of dams, dam abutments, and upstream slopes during and after impoundment.

-Monitoring settlement profiles of embankments, foundations, and other structures (horizontal inclinometer).
