Towards an automatic early warning system of flood hazards based on precipitation forecast: the case of the Miño River (NW Spain)

<p>An early warning system for flood prediction based on precipitation forecast is presented. The system uses rainfall forecast provided by MeteoGalicia in combination with a hydrologic (Hydrologic Modeling System, HEC-HMS) and a hydraulic (Iber<span class="inline-formula">+</span>) model. The upper reach of the Miño River and the city of Lugo (NW Spain) are used as a study area. Starting from rainfall forecast, HEC-HMS calculates the streamflow and Iber<span class="inline-formula">+</span> is automatically executed for some previously defined risk areas when a certain threshold is exceeded. The analysis based on historical extreme events shows that the system can provide accurate results in less than 1&thinsp;h for a forecast horizon of 3&thinsp;d and report an alert situation to decision makers.</p>
