Monitoring
Monitoring of ground movements, groundwater levels and pore water pressures was necessary for long-term monitoring to establish any impending instability.
Each site was instrumented with specially designed GEO- XW100 Long Wire Rotary Wire Extensometers, high-volume Rain Gauges and SGP-3400 Strain Gauge piezometers for observation wells and piezometers. In addition, several In-Place Inclinometers with up to 20 sensors were also installed in high risk locations complimented by and manual monitoring with Portable Inclinometers in other locations.
All instruments are individually equipped with radio enabled CR Series dataloggers and each site has a GSM connected Radio Gateway to provide remote data gathering and processing. The Gateways have the capacity to analyse the incoming local instrument data and trigger local alarm posts by SMS as well as sending alarm messages to specific key personnel.
Data from all 5 sites is gathered by a dedicated central server at the NBRO offices in Colombo using the GSM network and is presented using the standalone data visualisation presentation package. This provides visual alarm status overviews together with the details of data from each instrument. It also has the capacity to activate the alarm post on each site and send notifications.
