The need for monitoring slope movements increases with the increasing
need for new areas to inhabit and new land management requirements.
Rock-slope monitoring implies the use of a database, but also the
use of other tools to facilitate the analysis of movements. The experience
and the philosophy of monitoring the top of the Randa rockfall scar
which is sliding down into the valley near Randa village in Switzerland
are presented. The database includes data correction tools, display
facilities and information about benchmarks. Tools for analysing
the movement acceleration and spatial changes and forecasting movement
are also presented. Using the database and its tools it was possible
to discriminate errors from critical slope movement. This demonstrates
the efficiency of these tools in monitoring the Randa scar.
