Bangladesh announces nationwide use of SERVIR satellite-based flood forecasting and warning system

A press release from NASA: Bangladesh officials have announced plans to expand a satellite-based flood forecasting and warning system developed by SERVIR to aid an area where floodwaters inundate from 1/3 to 2/3 of the country annually, killing hundreds of people and affecting millions. The system, which relies on river level data provided by the Jason-2 satellite, last year provided the longest lead time for flood warnings ever produced in Bangladesh.

SERVIR is a joint development initiative of NASA and USAID, working in partnership with leading regional organizations around the globe to help developing countries use information provided by Earth Observing satellites and geospatial technologies for managing climate risks and land use. SERVIR and the International Centre for Integrated Mountain Development based in Kathmandu, Nepal, developed the Jason-2 based flood forecasting and warning solution.

"Forecasters have the dream to extend lead time for flood warnings," said Amirul Hossain, executive engineer for the Bangladesh Water Development Board. "By using Jason-2 near real-time data, we made a real step forward in the flood forecasting system in Bangladesh."

About 80 million people depend on the BWDB Flood Forecasting and Warning Center flood warnings. This organization has progressively built and expanded its flood forecasting system. However, without data from Jason-2, warnings were issued just three to five days in advance of flooding. During the 2014 monsoon season, the FFWC used the new Jason-2 solution experimentally and was able to forecast flooding eight days in advance at nine locations of the Ganges and Brahmaputra River Basins in the north, northwest, and central part of the country.

..."We hope this is the beginning of a new journey, a new era for further development of the flood early warning system using space data or space technology,” said Hossain. “In the coming year, with support provided by the NASA SERVIR team, we would like to expand the system to many other locations where possible, to enable more people to benefit from this system by receiving more extended lead time for flood forecasts."...
