GUWAHATI, June 25 - As part of the nationwide programme to adopt modern technology to alert Railways regarding abnormal rise in water level of major rivers, the Northeast Frontier Railway (NFR) installed a system based on radar technology on the Saraighat bridge here recently.

The system will automatically and continuously monitor the water level in the Brahmaputra and send SMS to predetermined cell phones at regular intervals.

�This automated system is an improvement over manual mode of recording being adopted so far. Soon it will be integrated with the Railways� Track Management System. Similar systems will be installed in a total of 10 bridges within NFR very soon. Railwaymen looking after the system will get alerts as soon as the water level in the river crosses danger level, so that train services can be suitably regulated to obviate any danger,� said an official statement.

In this system, electro-magnetic waves generated in the instrument pass through the air and reaches water surface before coming back to the sensor. The distance between the instrument and water surface is calculated from the travel time of waves. �Thus, a very accurate and reliable level of water is found. From site, the data goes directly to the Master System through GPRS. Alert signals are automatically sent to cell phones and TMS through an Internet-based system,� said the statement.
