Figure 2:The new hybrid approach for vulnerability assessment
As it was mentioned in early statements, it is advisable to generate a
new approach with the combination of security risk modeling consist of
inherent characteristics of assets and their attractiveness with
hydraulic and hydrological characteristics of flood and floodplain area
in contact with downstream assets. Thus, the parallel approach is needed
to provide appropriate risk analysis steps besides flood mapping and
horological analysis. As illustrated in Figure 3, the task of risk
analysis is carried out by performing a modified SVA method. On the
other hand, the hydraulic model is developed by HEC-RAS to extract the
vulnerable factors of flood risk as to the height and velocity of water
flow. Then, the SPRC method is applied as a connection bridge between
these two parallel calculations to finalize the risk map based on the
Geographical Information System (GIS). Figure 3 is illustrating the
models and tools according to this research.
