Short summary
This work presents a multiparametric analysis of hydrological, meteorological, and seismic data to characterize a major flood event in the Tagliamento River (Italy). River-generated seismic noise, related to flow and bedload transport, is detected up to 3 km from the channel. Cross-correlation and polarization analyses of the November 2023 "Ciàran Storm" reveal a clear PSD (Power Spectral Density)–water level relationship with hysteresis.
