    Guwahati now has an Automated Early Warning System to predict Urban Flood

    With its launch on Thursday, Guwahati became the third city in the country to have a flood warning system

    GUWAHATI: Assam’s capital city of Guwahati has now equipped with a Flood Early Warning System (FEWS) to predict urban floods. The city has been reeling under waterlogging and urban flood during the monsoon season.

    The Energy and Resources Institute (TERI), in collaboration with India Meteorological Department (IMD) and National Disaster Management Authority (NDMA), has developed a fully automated web-based Flood Early Warning System (FEWS) to predict urban floods in the city.

    With its launch on Thursday, Guwahati became the third city in the country to have a flood warning system. Only Chennai and Mumbai have the system so far.

    Using IMD’s weather research forecast (WRF) model, the system was developed at 10-meter spatial resolution with inbuilt urban drainage to predict flood at street-level accuracy three days in advance.

    TERI said that flood level and flood hotspots areas can be visualised over Google Maps which would help in identifying flooded areas, preparedness and management of related issues such as traffic disruption, providing relief and recovery and stormwater management.

    It added that the tool uses the weather forecasting data from IMD and simulates the floods that any forecasted heavy rainfall event can bring over the city region. The tool will also send out alerts to the concerned agencies if the rainfall or flood level crosses its threshold.

    The Assam Disaster Management Authority (ASDMA), Guwahati Municipal Corporation and North-East Space Application Centre were also involved in developing the system.
