“…To analyze coastal flooding, it is necessary to know the coastal dynamics and the factors that influence it, which can be mainly grouped in natural and anthropic factors [3][4][5][6]. These factors have increased the vulnerability of coastal areas to natural events [7][8][9][10][11][12]. Regarding the anthropic factors, the most important are the construction of infrastructures, ports and coastal defense works [13][14][15].…”

Coastal flooding is a danger to people who live near coasts. It is therefore necessary to increase knowledge of the causes of coastal flooding through scientific research. Furthermore, the correct assessment of flooding areas is very important for the management of coastal areas. Given this, the current European legislation (Directive 2007/60/EC) requires flood areas to be mapped, but to date in Italy each region is still adopting different procedures to map their flood areas. This paper, through two case studies, analyzes the hazard, damage and risk mapping of coastal flooding areas. The cases are related to two Calabrian towns, located along the Ionian coast (Monasterace), and the Tyrrhenian coast (Scilla), with both particularly prone to coastal flooding. In particular, with regards to the hazard mapping, the effects of sea storms and climate changes were taken into account. The damage assessment followed an "ex ante" approach, based on the employment of land use maps, in accordance with current Italian legislation. Furthermore, risk maps were added, and obtained by combining both damage and hazard maps. Finally, a comparison with previous events allowed us to verify the validity of the proposed methodology.

“…Anthropogenic pressure can increase the vulnerability of the territory under the action of natural events such as floods and sea storms [17]- [19], especially in case of concurrent events [20], [21]. Furthermore, the effects of climate change can contribute to erosive phenomena, in terms both of sea level rise and of frequency and intensity of extreme weather events.…”

In territories such as Calabria, Italy, characterized by about 750 km of coasts, the analysis of the coastal erosion risk is of increasing interest due to the considerable anthropic pressure observed in the last few decades. Index-based methods can be used to assess the risk of coastal erosion. The paper shows an analysis of the coastal erosion risk carried out in Calabria. The analysis was carried out in over 50 sample coastal areas, three of them were chosen as case studies for a detailed analysis. The analysis of the shoreline changes was carried out through the comparison of various cartography data, which consists of historical shorelines taken from the Open Data section of the Calabrian Geoportal, orthophotos taken from the Open Data section of the Italian Geoportal, and satellite imagery provided by Google Earth. The analysis was divided into four phases as follows. The first phase concerned the manual digitization of each missing shoreline, using QGIS for each orthophotos and using the spatial analysis tools of Google Earth Pro for each satellite imagery. The second phase concerned the evaluation of the beach width for each transept. Finally, the last phase concerned the determination of shoreline rates of change using end point rate (EPR) and net shoreline movement (NSM) statistics. Also, an index representative of the trend of erosion or advance of the coast was estimated. Finally, the methodology described in this paper is of particular relevance and interest in the planning and management of coastal areas. It allows us to quickly analyze cartographic data from different sources, using free software. Also, it is of general validity and is useful as a basis for the index-based coastal risk assessment methodology.

“…Generally, most studies in the scientific literature treat floods and sea storms in separate ways. However, the most critical aspects of floods and sea storms are observed in the case of concurrent events [46], [47]. Ordinariness of events becomes exceptionality during contemporaneity.…”

Analysis of the Concurrent Conditions of Floods and Sea Storms: A Case Study of Crotone, Italy

The considerable anthropogenic pressure that has occurred since the second half of the last century has increased the vulnerability of coastal areas to the effects of natural events such as floods and sea storms, especially if these events occur simultaneously. This paper analyses the conditions that favour the concurrence of floods and sea storms through a case study near Crotone, a city in southern Italy on the Ionian Sea. The study area has a coastal extension of about 34 km, is characterized by typical rivers called "fiumare" and has been hit by several events of concurrent floods and sea storms. The conditions that favour the concurrence of floods and sea storms are mainly related to geomorphologic and climatic factors. Among these latter factors, atmospheric pressure is very important. Indeed the formation of low-pressure areas is the cause of atmospheric disturbances which can affect both the sea and the coast causing heavy rains and intense sea storms. The analysis was divided into two phases. In the first, the concurrence between floods and sea storms was verified. In the second phase, the possible correlations between the main factors involved were identified: the rainfall heights, the maximum significant wave heights and the atmospheric pressure variations observed during each atmospheric disturbance. The analysis showed that the rainfall heights and the maximum significant wave heights, that are both generally independent factors, are related to a common factor, the atmospheric pressure. This result is useful in predicting concurrent events. Indeed, by predicting atmospheric pressure variations, it is possible to estimate the expected rainfall height and the expected maximum significant wave height. The methodology described in this paper can be extended to other areas with geomorphologic and climatic characteristics that are similar to those of Crotone.
