Environmental damage: Combining impact and vulnerability
BE-AWARE II Final Conference, 18-19 November, Ronneby, Sweden
Co-financed by the EU – Civil Protection Financial Instrument

Objective:1.How to combine Impact with Vulnerabilityto obtain Damage?2.The numerical result for damage must be applied to identify damage differences for different scenarios

Definition of Damage
General definition: Risk = Probability · Consequence, [EUR/year]Present definition: Risk = Probability · Impact·Vulnerability, [g oil'/y/m²)]Damage calculation: Integration of risk over frequencies and area, [g oil']
Damage is:•amount of oil in each cell, spilt due to accidents (including drift, etc.)•weighted according to env. and soc.-eco. vulnerability per cell•time-averaged (seldom big + frequent small spills) •summarised for a sub-region
Environmental damage: Combining impact and vulnerability

Addition of damage at surface and in water column: Impact x Vulnerability => Damage
All seasons, spill sizes, oil types, all winds, all accidents
Base case: Surface
Base case: Water column
Damage

• Oil on shore Mass of oil per shoreline in a specific sub-region. Combined with vulnerability of shoreline.
• Oil on surface mass (oil) per area water surface. combined with surface vulnerability
• Oil in the water columnmass (oil) per area water column (horizontal area – assuming 20-60 m layer thickness). combined with water column vulnerability
Environmental damage: 3 types of impact

Challenging question: How shall environmental and socio-economic Damage balance Impact and Vulnerability?
Mutual decision:Impact and Vulnerability shall be of equal consequence for environmental and socio-economic Damage
"100% Damage = 50% Impact + 50% Vulnerability"
Balance of impact and vulnerability

Frequency analysis of impact dataset: Range (0-10.000.000)=> dominant
Frequency analysis of vulnerability dataset:Range: 1-50
Frequency analysis of data sets

Impact: Unchanged (physical dimension)
Vulnerability: Transformed(index)
Range of the vulnerability data is transformed so range is equal in both data sets
Transformation of dataset
