The Streamflow Prediction Tool for Bangladesh provides 10-day forecasts for 21 specific locations on the river systems in Bangladesh. The Flood Forecasting and Warning Center (FFWC) uses the forecast data generated at these points for information on the flood situation and as inputs into their in-house flood forecasting model.
The Streamflow Prediction Tool provides predicted estimates by using runoff predictions from the European Center for Medium Range Weather Forecasts (ECMWF) routed through the Routing Application for Parallel Computation of Discharge (RAPID) model. The connection between the predicted and hind-casted runoffs is generated using different proprietary and open-source GIS tools.
The SERVIR Hindu Kush Himalaya (SERVIR-HKH) Initiative at ICIMOD worked with Brigham Young University to develop a custom Streamflow Prediction Tool for Bangladesh. The tool is built on Tethys, an open-source framework for developing web-based applications for Earth observation. The FFWC provided the 21 border locations and is using observational data from select locations to validate forecasts.
The web application displays the boundary locations provided by the FFWC along the Bangladesh border on a map. The graph above displays 10-day streamflow forecasts for a particular location and reflects the mean flow, the upper and lower standard deviation ranges, and the upper and lower outer ranges.
