Collected data form the basis for developing predictive models for assessing the effect of Mean Sea-Level variations.

The National Tsunami Early Warning Centre (NTEWC) of the Indian National Centre for Ocean Information Service (INCOIS), Hyderabad, recently installed a Sea-level Tide Gauge at Machilipatnam old port area to study real -time sea data.

The NTEWC is a premiere Tsunami Warning Centre of the Ministry of Earth Sciences, Government of India. Machilipatnam is one of the 14 coastal locations in India which were identified by the INCOIS to study the daily changes in the sea water level, wind speed and other Tsunami related data.

“We recently installed the Sea-level Tide Gauge at Gilakaladindi on the premises of the Survey of India’s weather monitoring station. We receive data on changes in the water level and tidal waves of the Bay of Bengal everyday. It is a real-time observation technology that tracks changes in the sea”, National Tsunami Early Warning Centre In-Charge T. Srinivas told The Hindu. He added that 31 gauges were installed across the country.

The other locations from where the sea data was being monitored are Chennai, Ennore, Haldia, Kandla, Karwar, Krishnapatnam, Marmagao, Nagapatnam, Paradeep, Port Blair, Vadinar and Visakhapatnam.

According to Ministry of Earth Sciences, the data collected from the sea-level gauges form the basis for developing predictive models for assessing the effect of Mean Sea Level variations and storm surges on the coast. Every day, the NTEWC receives data from seismic stations of the Indian Metrological Department and stations of the Wadia Institute of Himalayan Geology apart from the sea-level gauges for prediction of the storms and Tsunami.

ISRO Gauge

Indian Space Research Organisation (ISRO) in collaboration with Machilipatnam-based DMS SVH College of Engineering had installed a Cellular Based Microwave Radar Gauge near Gilakaladindi Harbour in 2012. The gauge records and disseminates data on tidal waves and turbulence inside the Bay of Bengal.
