Reconstruction of the 1974 flash flood in Sóller (Mallorca) using a hydraulic 1D/2D model

open access: yesJournal of Hydrology and Hydromechanics, 2023
Flash flood events are common in the Mediterranean basin, because of a combination of rugged coastal topography and climatological characteristics. The Balearic Islands are a flood-prone region with the research area, Sóller (Mallorca) being no exception.
