Abstract

In the last century the Amalfi Coast was affected by numerous severe floods in conjunction with exceptional rainfall that caused major damage in terms of lost lives and economic cost. Historical documentary sources are an important source of information for reconstructing exceptional flood events occurring prior to the instrumental era. Historical analysis also provides an opportunity to extend the time scale window for flood risk studies. To study historical floods we collected all the available information concerning the period between the 16th and the 20th centuries by analysing both published and unpublished sources. The great variety of historical sources made it necessary to formulate an ad hoc scientific procedure that takes into account not only the completeness and reliability of documents related to the period, but also the intrinsic quality of the material. Experience in historical data collection shows that not all documentary sources can provide useful information for flood characterization, but it is necessary to have a selective criteria in order to obtain the best information rather than the best dataset quality. Analysis of the data in question allowed us to achieve a chronological reconstruction of more than 100 floods. 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 effects induced.
