Log in to TNSMART for real-time flood alerts

TN SMART (Tamil Nadu System for Multi-Hazard Potential Impact Assessment and Emergency Response Tracking), a web-based system to strengthen preparedness, response, and mitigation measures for multiple hazards such as Flood, Cyclone and  Tsunami, Lightning, etc, was launched by Tamil Nadu on October 26, 2018.

One of the significant aspects of the system is the fact that it is aligned with priority areas set forth in Global Frameworks (the Sendai Framework, World MeteorologicalOrganization’s Global Framework for Climate Services and SustainableDevelopment Goals) as well as Tamil Nadu State Disaster Management PerspectivePlan 2018-2030.

TN-SMART also has a mobile application which can give access to observed rainfall data for all available rainfall stations, weather forecast and likely flooding in identified vulnerable areas. This application sends alerts to field-level functionaries and tracks the action taken by them on the same. Citizens too can send distress messages to the system, which are then forwarded to concerned officers for action. This mobile application has a unique alarm system that can send an alarm, even if mobiles are in silent mode. The alarm stops ringing only after the alert has been viewed. 

A diasggregated database of such calls (location of user, type of emergency, etc.), legacy data on vulnerable areas, vulnerable communities, disaster damage and crticical infrastructure such as hospitals, relief centres, etc. aids policymaking.

TN-SMART also uses data analytics to arrive at different thresholds, which, in turn, are used for arriving at specific advisories.

The system thus caters to policymakers, operational users as well as the communities. It helps policymakers prioritise Disaster Risk Reduction, operational users understand risk patterns, identify risk locations, vulnerable populations and plan the deployment of response teams and materials. The system empowers communities by helping them avoid risk by preemptive evacuation thus improving resilience.

It provides for an annual performance audit based on which improvements will be made in the system so that constant improvement are made. TN-SMART is a 360 degree solution for tracking, monitoring, evaluating and clocking progress on all aspects of disaster risk reduction.
