The forecasting system was designed by scientists at the National Center for Atmospheric Research (NCAR) and the Georgia Institute of Technology.\u003C\/p\u003E\n\u003Cp\u003EBangladesh is one of the most vulnerable regions on Earth to floods. Rising waters in recent days have left dozens of people dead and several million marooned or displaced, with the toll likely to mount.\n\u003C\/p\u003E\n\u003Cp\u003EThe 1- to 10-day forecasts are delivered directly, when possible, to more than 100,000 people living in floodplains of the Brahmaputra and Ganges rivers. They will be distributed more widely in coming years.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Our goal is that long-range flood forecasts, for the first time, will consistently reach many rural individuals in Bangladesh who are in jeopardy of losing their homes, businesses, and possibly their lives,\u0022 said NCAR scientist Thomas Hopson, who helped develop the forecasting system.\n\u003C\/p\u003E\n\u003Cp\u003EThe forecasting system predicted the current floods several days in advance, but volunteers on the ground cannot yet confirm the extent to which it helped people prepare for these floods.\n\u003C\/p\u003E\n\u003Cp\u003EThe system uses a combination of weather forecast models, satellite observations, river gauges, and new hydrologic modeling techniques. It is part of a larger initiative, known as Climate Forecast Applications in Bangladesh, to improve flood and precipitation warnings in the low-lying nation. Peter Webster, a professor in Georgia Tech\u0027s School of Earth and Atmospheric Sciences, is the principal investigator of the overall initiative.\n\u003C\/p\u003E\n\u003Cp\u003EHopson and Webster have provided forecasts to Bangladeshi agencies since 2003, but the forecasts often have not reached rural regions, where many residents lack radios and even electricity. This year, the Thailand-based nonprofit Asia Disaster Preparedness Center has established a network of governmental and nongovernmental organizations, as well as volunteers, to distribute the forecasts directly to people in five districts along the Brahmaputra and Ganges, including impoverished families living on islands known as river chars. The center\u0027s Ramasamy Selvaraju and A.R. Subbiah are overseeing the distribution efforts.\n\u003C\/p\u003E\n\u003Cp\u003EAdditional areas of Bangladesh will receive forecasts in coming years.\n\u003C\/p\u003E\n\u003Cp\u003EThe project, which has received funding from the National Science Foundation (NSF), is supported by the U.S. Agency for International Development and the relief agency CARE.\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EProtecting lives and income\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003EAlmost every other year in recent decades, the Brahmaputra and Ganges rivers have flooded for periods ranging from a few days to a month or more, often with devastating results for local residents. Farmers and fishers can easily lose a year\u0027s worth of income in a single flood.\n\u003C\/p\u003E\n\u003Cp\u003EResidents of the largely impoverished districts in the forecast area have said that advance notice of floods could help them ward off some of the worst impacts of rising waters. If they had sufficient warning, they could harvest at least a portion of their ripening crops, move some livestock to safety, encircle fish ponds with nets to prevent fish from escaping, and stock food and other supplies.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022The goal here is to help very local, grassroots economies,\u0022 Hopson explained. \u0022The forecasts also alert relief agencies to prepare to bring in drinking water, cholera tablets, and other essentials in case of a major flood.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe European Centre for Medium-Range Weather Forecasts provides data and weather forecasts, which are fed into hydrological models of the Ganges and Brahmaputra river basins. The system also incorporates estimates of precipitation from two satellite-based systems developed at the NASA Goddard Space Flight Center and NOAA Climate Prediction Center, along with discharge measurements of rivers in Bangladesh.\n\u003C\/p\u003E\n\u003Cp\u003EThe forecasting system emphasizes modeling and satellite data to compensate for a lack of river gauge data upstream of Bangladesh, as well as for a lack of radar data. It is updated daily with new model runs and measurements.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ELonger-range forecasts\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003EHopson, Webster, and Georgia Tech scientists Carlos Hoyos and Hai-Ru Chang have worked to create forecasts that go out more than 10 days, thereby giving residents additional time to prepare for floods. Over the next year or two, increasing numbers of Bangladeshis will begin to receive 20-day forecasts, followed by one- to six-month seasonal forecasts.\n\u003C\/p\u003E\n\u003Cp\u003EThe team will also study the feasibility of applying its forecasting technology and methods to other vulnerable countries, such as Cambodia and Vietnam.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We feel that the prediction modules we have developed for Bangladesh are templates for flood forecasting in developing nations with limited infrastructure and resources,\u0022 Webster said.\n\u003C\/p\u003E\n\u003Cp\u003EThe University Corporation for Atmospheric Research manages the National Center for Atmospheric Research under primary sponsorship by the National Science Foundation.

At the time, the forecasts were not fully integrated into Bangladeshi warning systems, and approximately 500 people in Bangladesh and India died in the floods. This summer, for the first time, the forecasts are being distributed directly to more than 100,000 people living in flood-prone areas along the Brahmaputra and  Ganges rivers.
