The phenomena involved in extreme fl ood events are complex and their prediction is affected by a given degree of uncertainty, that makes the warning communication very difficult to achieve. The
promotion of the natural hazards perception and the improvement in warning communication, aimed at human life losses reduction, therefore, became extremely desirable.
This work analyzes the disastrous fl ash-fl ood occurred on 19 June 1996 in the mountain river basins of the Apuanian Alps in Central Italy. The eve

According to the usual defi nition, risk is a combination of Hazard, Exposure and Vulnerability, representing the global damage amount connected to a particular event that may occur in a given area in a prefixed return time. According to the previous definition, a “multihazard risk analysis” needs a methodological approachable to combine in terms of effects several different natural events that may occur in an area. This analysis has the purpose of defi ning political and technical programs for risk mit

The availability of high resolution topographic data is strategic for quantitative and qualitative analysis of river environment. The topographic data derived by traditional regional cartography
are often too coarse for detailed recognition and mapping of surface morphologic features, while the more accurate data derived by GPS or theodolite are expensive and time-consuming. The airborne laser
altimetry technology (LiDAR, Light Detection And Ranging) provides high-resolution topographic data over large ar

This study analyzes the phenomenon of landslide dams by means of a quantitative approach, that consists in the implementation of a specific cellular automata model: CAESAR (COULTHARD et alii, 2002)
a 2D model developed to simulate the morphological trend of a river within its hydrographic basin, including the calculation of the flow depth and a more detailed representation of sediment transport using multiple grain sizes. A code modifi cation of CAESAR (DE ROSA, 2008) has been introduced to simulate a larg

This paper is about a statistical analysis and sensitivity analysis on the main factors directly involved in the landslide dam phenomena, meaning, for “sensitivity analysis”, “... the study of how the variation (uncertainty) in the output of a mathematical model can be apportioned, qualitatively or quantitatively, to different sources of variation in the input of the model ...” (SALTELLI et alii, 2008).
With this aim these parameters have been linked each other with a dimensionless index which desc

Today, although the authorities responsible for the risk management have modular and institutionalized plans of communication, communicative practices, during all the stages of risk management, often appear to be fragmented, with no standardized codes and without a correct grammar that makes them coherent.
At best, this produces an ineffective risk communication.
At worst, a communication that is not able to make use of a consolidated and shared language can induce the receivers of the communication itsel

This paper aims to analyze the systemic vulnerability of an area as complex as urban when a fl ood and landslide occurs. The proposed approach of vulnerability evaluation, differs from those who prefer
the traditional physical sense because of it provides an analysis of “systemic vulnerability” measuring the relationship between extreme event’s magnitude and direct and indirect consequences of this event on the territorial system.
The model is an application of a mathematician-decisional model actio

The study of flooded areas is derived from detailed knowledge of the area under consideration (river and floodplain), hydrological analysis and hydraulic modeling.
The estimated risk of fl ooding is now facilitated by survey systems able to create enable the creation of highly detailed digital terrain models (COBBY et alii, 2001), by complex mathematical
models and sophisticated hardware and software which permit the achievement of complex elaborations within satisfactory time periods.
However, the const

A detailed study on riverbank retreat is reported with the aim to investigate on advantages and limitations of a high-resolution methodology such as terrestrial photogrammetry, and to quantify the sediment eroded from a representative reach of riverbank during a period of about 30 months.
The study reach is located along the Cecina (Tuscany, Italy). Bank deposits were surveyed and grain size analyses were carried out for the main levels.
In the monitoring reach, analytical and digital photogrammetry have
