||The Natural Hazards Review project will develop a framework and best practice approach to characterise natural hazards and seek to improve methodologies where current approaches are inefficient. This is to improve energy system infrastructure design and the project is intended to share knowledge of natural hazards across sectors. The project will be completed in three stages. Phase one will focus on a gap analysis. Phase two will look at developing a series of improved methodologies from the gaps identified in phase one, and phase three will demonstrate how to apply these methodologies. Finally, phase 3 will develop a “how to” guide for use by project engineers.
This case study illustrates the appropriate use of the methodology from the technical volumes for Cottam, England. Cottam is located in the East Midlands region of England. The site was chosen as representative of an inland river environment. This case study provides an assessment for the river flooding hazard. The aim of this case study is to assess flood risk, mainly from fluvial and tidal sources; risk of flooding from other sources, such as surface water and ground water flooding, have also been considered. All relevant key data associated with flooding, such as river water levels, sea levels and river discharges, have also been presented. Hazard characterisation is shown for
- Flood risk
- Fluvial flooding
- Tidal influence and extreme sea level
- Astronomical tide
- Artificial sources of flooding
