3 . 5 Hydrological risk : landslides
نویسندگان
چکیده
The term landslide encompasses a wide variety of phenomena, from the simple fall of rock blocks from vertical rock faces, through to topples and landslides that are dominated either by a sliding motion or by flows of soil and/or rock. Landslides are strongly correlated with other types of natural hazards, such as floods, droughts, wildfires, earthquakes, tsunamis and volcanoes, and are often involved in cascading events of multihazard disasters.

Information system on hydrological and geomorphological catastrophes in Italy (SICI): a tool for managing landslide and flood hazards
Since 1990, we have maintained a database of historical information on landslides and floods in Italy, known as the National Research Council’s AVI (Damaged Urban Areas) archive. The database was originally designed to respond to a request of the Minister of Civil Protection, and was aimed at helping the regional assessment of landslide and flood risk in Italy. The database was compiled in 1991...
متن کاملLandslides Hazard Assessment Using Different Approaches
Romania represents one of Europe’s countries with high landslides occurrence frequency. Landslide hazard maps are designed by considering the interaction of several factors which, by their joint action may affect the equilibrium state of the natural slopes. The aim of this paper is landslides hazard assessment using the methodology provided by the Romanian national legislation and a very largel...
متن کاملEffects of land cover changes induced by large physical disturbances on hydrological responses in Central Taiwan.
This study analyzes the significant impacts of typhoons and earthquakes on land cover change and hydrological response. The occurrence of landslides following typhoons and earthquakes is a major indicator of natural disturbance. The hydrological response of the Chenyulan watershed to land use change was assessed from 1996 to 2005. Land use changes revealed by seven remote images corresponded to...
متن کاملDistributed modelling of shallow landslides triggered by intense rainfall
Hazard assessment of shallow landslides represents an important aspect of land management in mountainous areas. Among all the methods proposed in the literature, physically based methods are the only ones that explicitly includes the dynamic factors that control landslide triggering (rainfall pattern, land-use). For this reason, they allow forecasting both the temporal and the spatial distribut...
متن کاملEffects of damaging hydrogeological events on people throughout 15 years in a Mediterranean region
Damaging Hydrogeological Events (DHE) are defined as rainy periods during which landslides and floods can damage people. The paper investigated the effects of DHE on people living in Calabria (southern Italy) in the period 2000– 2014, using data coming from the systematic survey of regional newspapers. Data about “fatalities”, people “injured” and people “involved” (not killed neither hurt) wer...
