  • The Salerno rocky coast (Campania, Southern Italy) is particularly subject to the hydrogeologic risk (landslides and flooding), which represents a threat to the natural environment and a persistent menace to urban areas, in terms of human lives, socio-economic costs and modification of the landscape. A reliable time frequency of the flood recurrence is the most useful tool for flood risk assessment and it requires long time series obtained mostly from historical data. The coast of Salerno province experienced numerous flooding events after heavy thunderstorm, that triggered intense landslides, inundations, denudation, shore line progradation etc. In this paper, we present a reconstruction of historical floods occurred along the about 25km of the Amalfi coast, on the basis of different documentary sources. Analysis of the data allowed to achieve a chronological reconstruction of more than 100 floods, four of which have been classified as catastrophic events. In this task, the level of information was decisive to carry out space–time identification, estimate the affected area and define type of damage to public and private structures, and the geological-induced effects (e.g. mud flow, debris flow, rock falls, shoreline progradation) fan deltas ), which may be relevant for the recognition of similar events within the geologic record. The magnitude of the events was finally estimated, taking into account the size of the areas affected by flooding, the type of effects induced on the urban and physical environment and the recurrence intervals (literal)
