Example 1: Relative damage to residential buildings
In the demoBN relative damage to houses is influenced by the max. inundation depth at the house as well as the effective implementation of the measure "Protect buildings with sandbags":
The This vulnerability mapping is based on the flood damage curve for Belgium in the CVI library. Additionally the assumption has been made that sandbags can withstand a flood depth of 50cm, which means that depths less than 50cm do not lead to damage, because the building itself is kept dry, while depth higher than 50cm lead to the same damage as before, because the bags overflow. The node "Implementation" does not need to be taken into account. Its influence is fully specified by the "effectiveness" in the Mnodes.json file.
In other words full effectiveness can be assumed when determining the mapping.
The mapping [1,1,3,4,1,2,3,4] (cf. the vulnerabilities.json file) can be obtained from the following tableThe corresponding table is:
| State of "Sandbags" | State of "I_ResBuildings" | State Index of "RelDamage_ResBuildings" |
| Yes | [0, 0.01] | 1 |
| Yes | [0.01, 0.5] | 1 |

Example 2: Risk to Life
Risk to Life is influenced by the max. flux people are experiences, the distribution of people and the measure evacuation being in place or not, see below illustration.
This mapping is based on the risk to life matrix for the UK from the CVI library. The assumption is made that Area1 and Area2 have low vulnerability, Area3 has medium vulnerability and Area4 has high vulnerability.
The resulting mapping is [1,1mapping [1,2,2,3,3,5,1,1,1,1,1,1,1,2,2,3,3,5,1,1,1,1,1,1,1,2,3,3,4,5,1,1,1,1,1,1,1,2,3,4,5,5,1,1,1,1,1,1] can be obtained from
