| 摘要： | We have developed a generic prototype of a flood-forecasting model transferable to other locations around the Midwest to provide monitoring and forecasting flood potential at critical infrastructure points, such as bridges, where streamflow gauges are not available. A real-time web-based visualization platform to display the model predictions has been implemented. The platform will display the river network upstream from a point of interest and a time control slider that will allow exploring the evolution of flows everywhere in the network over the past several days, and about a week into the future. The model uses in-house developed radar-rainfall maps updated every 5 minutes with the spatial resolution of about 0.5 km currently covering the Iowa domain and extending some 100 km into the neighboring states. For future rainfall, we use predictions for the National Weather Service High-Resolution Rapid Refresh (HRRR) forecasting system. The system provides hourly accumulation products for up to 20 hours ahead. Our system expands the forecasting capabilities of the current NWS by providing predictions at locations that have not been historically gauged. |
