PARTNERSHIP

3. The aims of the Natural Hazards
Partnership (NHP)
• to deliver:
– a forum for the exchange of knowledge, ideas,
expertise, intelligence and best practice in matters
relating to natural hazards;
– a common and consistent source of advice to
government and emergency responders for civil
contingencies and disaster response;
– an environment for the development of
coordinated multi-hazard products and services.

9. Hazard Impact Model
Adding the Impact – who and what is affected
Identification of receptors –
people, property, infrastructure
Estimation of
vulnerability
Modelling of Impact

10. Hazard Impact Model
Hazard Impact Model – 3 priority hazards
- Surface Water Flooding (CEH)
- High Winds (MO)
- Landslides (BGS)

Delivery of:
- Proof of concept SWF HIM for testing & initial verification work
- Research report proposing methodology for operational SWF HIM

12. Wind Hazard Impact Model
Proof of concept - Vehicle Overturning (VOT) Model
Probabilistic model uses MOGREPS-UK ensembles: runs in
real-time – used for NSWWS
Prototype Models – Bridges and Camping
Ongoing work -
Wind Impacts on Buildings
Improve Wind Hazard Modelling
Verification of Hazard Impact Model
