    “The term “landslide” describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these.” (USGS, 2004).

    A change in the stability of a slope can be caused by a number of factors, acting together or alone, natural (groundwater pressure, toe erosion, earthquake, etc...) or occurring with human activities (blasting, excavations, constructions, etc...)

    Instrumentation in landslides usually monitors not only the body of the landslide, but also the buildings in the area, the protective structures, the weather parameters and, if needed, seismic parameters.

    LANDSLIDE TYPES

    • Rotational landslide

    • Translational landslide

    • Lateral slide

    • Rockfall

    • Topple

    • Debris flow

    AIMS

    • Landslide early warning system (EWS)

    • Monitoring of buildings in or nearby landslide areas

    • Railway and road safety

    • Monitoring performance of protective structures

    OMNIALOGDATA ACQUISITION SYSTEM

    The OMNIAlog system is designed to be versatile and flexible. By adding modular components to OMNIAlog datalogger, the systems can be configured to handle the simplest or the most complex projects.A single logger, housed in a cabinet with multiplexer expansion boards and a communications interface, can manage a large number of sensors. The systems are easily adapted for different applications by using external multiplexer boxes. Such distributed systems can be connected in a daisy chain or star configuration. Recorded data can be downloaded to a USB memory stick or pushed to remote ftp servers. Alerts can be sent by SMS or email, and graphs and reports can be generated on web pages for access anywhere.

    The WMS is a software platform designed and developed by Field Srl to validate, process, convert, manage, and automatically display data and graphs from geotechnical, structural, dynamic, meteorological and environmental monitoring systems.OMNIAlog and miniOMNIAlog dataloggers, equipped with any communication inteface, send data to a remote server. The server then validates the data, removing spikes and anomalous readings, and processes the readings, converting them to engineering units, and finally adding them to its SQL database. The readings are then made available in the form of charts or tables through the “Galemys” application. The entire process is automated so that current data is available 24 hours a day, 7 days a week.If a reading value exceeds a preset alarm threshold, the WMS can send an alarm notification via SMS or e-mail to the mobile phones of registered users.
