Reconstructing the 1874 Santa Tecla flash flood in the Ondara River (Ebro Basin, NE Spain)

摘要

The Santa Tecla flash flood, a very heavy event occurred in Tàrrega(Catalonia, NE Iberian Peninsula) in 1874, was reconstructed withhydraulic and hydrological modelling tools. The hydrograph obtained in afirst stage and the basin soil moisture information ultimately allowed theestimation of the range of the rainstorm magnitude which caused theflash flood. The reconstruction of historical floods has proved useful to improve theflood probability analysis, especially in ungauged basins.
