“…Risk is closely linked to the concept of vulnerability of the coastal areas exposed due to excessive anthropization, which has increased in the past 50 years. The aim of coastal zone management is a correct connection between economic, social and political needs that allow reducing the risk factors as much as possible [28]- [32]. There are two steps to follow in the risk analysis and management of the area considered:…”

Tsunamis are catastrophic events that occur especially in the Pacific or the Indian Ocean, causing violent inundations and destroying entire cities near the coast. They can also occur in the Mediterranean Sea, but their magnitude is smaller than in the Pacific or Indian Oceans; their effects however can be as fatal, because of high coastal exposure and vulnerability. These have been growing in the last few years as a result of increased coastal anthropization. This situation leads to a careful reflection on assessments of tsunami hazard due to earthquakes or landslides and of the consequences of tsunami impacts. The paper discusses these issues through an application along the Calabrian coasts in southern Italy. Our analysis starts from the description of the phenomena that have already taken place in order to assess the risk associated with any tsunami and to manage the consequent risk affected areas. Tsunamis are due to earthquakes or landslides mainly because of the high seismicity of the particular area. Many seismic events took place over time causing the onset of landslides and coastal floods. In particular the most catastrophic were the landslide-induced tsunami in Scilla in 1783, and the tsunami in the Strait of Messina in 1908, both in Calabria. In our case study, the Scilla tsunami has been treated with reference to the reconstruction of the landslide that induced it and the related flood. It is important to interpret the mechanisms of induction and propagation of these phenomena through events that have already occurred. In this way, we can have a complete picture of the risk and management of these phenomena in our territory, essential for human safety. The reconstruction of the event was made using QGIS and MATLAB software. QGIS was used to reconstruct the geometric domain, to interpret bathymetric data provided by the IGM (the Military Geographical Institute) and to map areas with risk of flooding, necessary for the management phase. MATLAB was used to reconstruct landslide geometry and the propagation mechanism.

“…In Reggio Calabria there are more than 10 fiumare and, not far from the Sant'Agata, there are the Calopinace, Armo and Valanidi rivers, all enclosed in a few kilometers. The study area is heavily anthropized due to the presence, especially, of the airport, between Sant'Agata and Armo rivers, a sport center and various industrial activities ( Figures 2-3) (Versaci, Minniti, Foti, Canale, & Barillà, 2018).…”

The analysis of shoreline changes is very important for coastal planning and management. In territories such as Calabria (Italy), characterized by significant anthropogenic pressures and various eroded coasts, the knowledge of the shoreline changes, and the factors that influence them, is necessary for management and planning of coastal areas. In fact, shoreline position is one of the most important indicators of coastal dynamics. From this point of view recent advances in remote sensing and GIS techniques allow to estimate with great precision the shoreline changes over the years. The paper analyzes the shoreline changes near the mouth of the Sant'Agata River (Reggio Calabria, Italy), carried out through the comparison of various cartography data. Furthermore, the paper analyzes the main factors influencing the coastal dynamics in order to identify possible correlation between these factors and the shoreline changes. The analysis of these factors shows that, in this case study, the rainfall regime has a considerable influence on shoreline change. The methodology described in this paper is particularly useful for better understanding the factors that most influence the coastal balance and, therefore, is applicable to many contexts which are similar to the Sant'Agata river mouth.

“…This paper, following and expanding upon the study by Versaci et al [75], evaluates the effects of anthropogenic pressure in the last 70 years on some rivers of the Metropolitan City of Reggio Calabria, through the comparison of cartographic data of different years using QGIS. The main goal is to evaluate the effects of anthropogenic pressure in terms of the following issues: planform changes, channelization, culverting, and the presence of structures and infrastructures interacting with rivers.…”

In the second half of the twentieth century, after the end of the Second World War, a considerable anthropogenic pressure was observed in most of the Mediterranean territories. This process has caused the expansion of existing settlements and the construction of numerous new towns, often located very close to rivers. A frequent consequence of this process is the transformation of several rivers through planform changes, narrowing, channelization and culverting to recover spaces where inhabited centers expanded, and the construction of structures interacting with rivers. This issue is very important in territories such as the Metropolitan City of Reggio Calabria, in southern Italy, which is an interesting case study due to the considerable anthropogenic pressures observed in the last 70 years. The main goal of this paper is to evaluate the effects of anthropogenic pressure in the last 70 years on some rivers of the Metropolitan City of Reggio Calabria in terms of the following issues: planform changes, channelization, culverting, and the presence of structures and infrastructures interacting with rivers. The specific goals of this paper are the quantification of the effects of anthropogenic pressure on the rivers of the study area analyzing sixteen parameters, the identification of possible conditions of hydraulic hazard through the analysis of past events, and the proposal of structural and non-structural mitigation interventions. In many rivers of the study area, the significant effects of anthropogenic pressure are visible through rivers that pass above highways, barred rivers, rivers replaced by roads and numerous crossing roads with a missing levee.
