Sumario:[EN] This article presents MERLIN, a tool for flood hazard evaluation, which forecasts discharges and water depths in flood prone areas of the Galicia Costa district. The warning system operates in two stages. During the hindcast stage, hydrological models of the basins included in the system assimilate hydro-meteorological data in order to characterize soil infiltration capacity. During the forecast stage, hydrological models are fed with meteorological predictions and discharge forecasts along the basins. Forecasted discharges define boundary conditions of hydraulic models, which compute the flood extent and the water depths over the upcoming days. The performance of MERLIN was evaluated in 4 areas using discharge data from the winter months of 2019-2020. Results proved MERLIN’s ability of predicting the discharges observed afterwards.
