There are many options for slope monitoring ranging from the several short-term, inexpensive solutions to more costly and long term programs. The inaccessible setting of many unsteady slopes has resulted in the need for the development of systems that can be remotely accessed and provided fast and efficient warnings in case of a failure. With the advancements in technology, it is now possible to employ slope monitoring economically and accurately.
Slope monitoring techniques requires selecting some definite parameters and observing changes in them over a period of time. The most important parameters that are normally taken into consideration are displacement and ground water levels. Slope dislocation is characterized by the direction, rate, magnitude and depth of failure planes. Conventional slope monitoring employed the usage of either a single method or a combination of several methods.
