example to study the spatial distribution characteristics of flood disaster risk.Based on AHP,weights are assigned to the evaluation indicators of flood disasters in the system,and the risk visualization is carried out in GIS.According to comprehensive risk assessment results,it could put forward ...
disaster risk assessment model based on Copula-EVT,which reflected the extreme process about drought disaster and impact factor.Empirical analysis of the Huaihe River in Bengbu station verified that Clayton Copula-EVT model could fit the historical experience of drought risk distribution of Bengbu ...
This study takes Tunxi area, Huangshan City of China, as an example. After risk assessment and forewarning model establishment and application for flood disaster at different spatial-temporal scales between the actual and simulated data from 1989 to 2008, forewarning results show that the development...
A disaster recovery plan must make it clear what are your organization’s: RTO—the maximal time your organization can tolerate for recovering normal operations in case of a disaster (for example, recovery within 30 minutes, 2 hours, 12 hours) RPO—the maximal amount of data your organization ...

Based on the complex networks theory,an idea or method of risk analysis and controlling on natural disasters evolution system is proposed.Taking the Morakot as an example,the network model including 30 crisis nodes and 39 evolution connections is established.The out-in degrees,number of nodes in ...
Paying attention to the difficulties of taking measures against all of the cases on estimated damages, we give an example of the rule of making decision about the priority of mitigation plans from the point of view of earthquake engineering and political science. 展开 ...
After analysing systematically formation mechanism of snow dis- aster (SD), this study revealed spatial-temporal characteristics of historical disasters, snowfall events, disaster-formation environ- ment, livestock overload, vulnerability of livestock and adaptabil- ity, finally evaluated integrated risk in...
On this basis, a risk assessment model of typhoon disaster chain based on Bayesian network is established. Taking Fujian Province as an example, the risk associated with the typhoon disaster chain is assessed, verifying the effectiveness of the method. This study provides a scientific basis for ...
(2) There is a positive correlation between the Vulnerability Index and the risk value of the disaster factor layer, for example, the Vulnerability Index of the Flooding Risk Factor Layer (C11) was much higher than that of the Sea Level Rise Risk Factor Layer, the Storm Surge Risk Factor ...
