3. EU ‘FLOODS’ DIRECTIVE - 2007
ARTICLES 4 & 5 – ‘PFRA’
Objective: To Identify APSFRs, or ‘Areas for Further Analysis’ (AFAs)
Based on ‘Available & Readily-Derivable’ Information
Range of Sources of Flood Water
Adverse Impacts on Human Health, the Environment, Cultural Heritage and the Economy

4. OVERVIEW OF PFRA OVERALL APPROACH IN IRELAND Risk Assessment (Art. 4)
‘Historic’ FRA (What has happened)
‘Predictive’ FRA (What could happen)
Consultation
Identification of AFAs (Art. 5)
Identify ‘Significant’ Risk
Identify AFAs

5. ‘PREDICTIVE’ PFRA FLOOD RISK – FUNCTION OF:
Probability of a Flood Event (Hazard)
Consequences (Damage in Event of a Flood)

6. ‘PREDICTIVE’ PFRA PROBABILITY National Indicative Flood Maps
Not Precise Flood Extent Maps
Acceptable Accuracy for PFRA (Readily-Derivable’)
Range of Sources of Flooding

11. ‘PREDICTIVE’ PFRA CONSEQUENCES Different ‘Receptors’
People, objects, areas and activities that could suffer harm or damage in the event of a flood
Criteria: Social, Economic, Environmental, Cultural
Vulnerability Assessment
Function of:
Receptor value / importance
Potential degree of damage to Receptor in event of flooding
Assign ‘Vulnerability Classification’

12. ENVIRONMENTAL VULNERABILITY
DATA REQUIREMENTS
Location
GIS Data: Location & Extent of Natura 2000 Sites (SACs, SPAs)
No Data on Location of Species within Sites
Classification
Designated / Selection Species
Vulnerability
No Data on Vulnerability to Floods

13. ENVIRONMENTAL VULNERABILITY
VULNERABILITY ASSESSMENT
Undertaken by Ecologists
All Species of Equal Importance
Assessment took into account:
Water-Dependency of Habitat / Species
Living, Breeding, and Feeding Habits
Siltation / Sediment Effects
Sensitivity to Nature of Flooding (e.g., duration)
Importance of Site for National / EU Population
Site Vulnerability based on highest vulnerability of all species within each site

15. ENVIRONMENTAL VULNERABILITY
RISK ASSESSMENT
Function of:
Vulnerability Classification
Probability of Flooding
Provisional ‘Flood Risk Index’ (FRI)
Final FRI: Factored by Proportion of Site Prone to Flooding for each Event Probability (10%, 1% and 0.1%)

16. CULTURAL VULNERABILITY
DATA REQUIREMENTS
Location
GIS Data: Location of WHSs, National Monuments (Appx. 110,000), Museums, Archives
Classification
Classification of Type
Vulnerability
No Data on Vulnerability to Floods

17. CULTURAL VULNERABILITY
VULNERABILITY ASSESSMENT
Importance:
Undertaken by Archeologist
Based on Classification (Not Individual Site)
Importance Criteria:
World Heritage Sites (International)
National Monuments
Rarity
Representation of Period
Diversity of Significance

18. CULTURAL VULNERABILITY
VULNERABILITY ASSESSMENT
Susceptibility:
Undertaken by Archeologist
Based on Classification (Not Individual Site)
12 Susceptability Criteria, Incl.
Age (evidence of resilience)
Location (river features)
Above / below ground
Material (stone, earth, wood, etc.)

20. CULTURAL VULNERABILITY
RISK ASSESSMENT
Function of:
Vulnerability Classification
Probability of Flooding
Final ‘Flood Risk Index’ (FRI)
