Isro, Andhra University To Develop AI-Based Beach Safety System

VISAKHAPATNAM: India's coastal safety framework is set for a technological upgrade through Project Bharati, a joint initiative of the Space Applications Centre (SAC) of Isro (Indian Space Research Organisation) and Andhra University, to develop an AI-enabled rip current detection and warning system aimed at reducing drowning incidents along the country's beaches.

Dr S.V.V. Arun Kumar of SAC-Isro and Prof. C.V. Naidu of Andhra University's Department of Meteorology and Oceanography are leading the two-year ₹22 lakh project. Their initiative builds on years of research into rip currents along the Visakhapatnam coast, where such currents are frequently observed near drainage outlets and stream mouths.

Rip currents are powerful channels of water flowing away from the shore that can rapidly pull swimmers into deeper waters.

Researchers are developing software that combines satellite imagery, weather data, oceanographic information, and live video feeds to predict and detect rip currents in real time. Officials said nearly 60 per cent of the software development work has been completed.

A key component of the project is the proposed Next-Generation AI Lifeguard Alert System, a mobile safety unit equipped with 360-degree AI-enabled cameras, thermal imaging for night-time monitoring, and weather stations that record wind speed, temperature, humidity, and atmospheric pressure. The system will continuously analyse these inputs and classify beach zones as safe, caution, or danger areas.

Officials point out that rip currents can move at speeds of up to five metres per second and extend between 50 and 150 metres into the sea. As these currents are often difficult for beachgoers to identify, an early warning mechanism could significantly improve public safety.

Under the proposed system, detection of a rip current will trigger sirens, flashing lights and public announcements. Simultaneously, alerts will be sent through 4G and 5G networks to lifeguards, coastal security police personnel and control rooms. Real-time safety information will be displayed on electronic boards for visitors.

Each solar-powered beach safety mobile unit, mounted on a movable platform, is estimated to cost ₹2 lakh, enabling deployment at different beaches depending on seasonal conditions and risk levels.

Officials said the pilot project is expected to benefit agencies including the coastal security police, GVMC, tourism department and the beach management authorities.

If successful, the Isro-AU system would be expanded to beaches across the country.
