Dam Safety Monitoring, NSW, Australia

During spring in Canada, snow melt runoff can cause rivers to swell and inundate rail bridges and culverts. The remoteness of most of Canada rail network means zero cellular coverage making it previously difficult to monitor.  EWS Iridium Devices were paired with hydrostatic level sensors to provide river monitoring and flood warning systems for remote rail bridges and culverts in Alberta, Canada. 

Four large TSF's in Australia's Northern Territory and Northern Queensland area retrofitted 1000's of vibrating wire piezometer sensors with EWS' Iridium VWT devices to replace the unreliable radio datalogger networks previously installed. The upgrade provided the TSF's with the easy to install devices which transmit individually over the Iridium Satellite network, removing the risk of single point failure. The increased reliability and visibility of critical geotechnical data relating to the TSF assists the mine in meeting its GISTM obligations.
