Figure 2:The new hybrid approach for vulnerability assessment
2. Methodology
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.
