Abstract:

Real-time riverine forecasting by the National Weather Service NWS is disseminated to the public via Weather Service Offices WSOs located in all states within the Nation. The WSO offices are assisted in the preparation of the riverine forecasts by regional offices called River Forecast Centers RFC and by the National Hurricane Center NHC in Miami. Riverine forecasts are primarily concerned with the prediction of water surface elevations at principal locations river forecast points along most of the major and many of the lesser rivers in times of flood, and at many locations on a daily frequency. The floods and lesser rises of the rivers may result from rainfall andor snowmelt runoff, reservoir release flows, hurricane storm surges, and dam failures. In addition to water surface elevations, forecasts are often provided for flow discharges and velocities. Such forecats are used for a multitude of purposes, e.g., water supply, navigation, irrigation, power, reservoir operation, recreation, and water quality interests.
