Climate Risk Engines use datasets from the past 20 years to calculate flooding probability, combining this information with satellite data and algorithms to account for local conditions. Contextual information used to determine risk of riverine flooding in an area include local rainfall data, surrounding waterway depths and previous records of flooding events.
Climate Valuation analysis considers the design, materials used and height above ground for each individual property to provide a comprehensive view of the current and future flood risks to property.
The vulnerability of a property to flooding is driven by the characteristics of the building (e.g. floor height, building materials, foundation type). Building materials respond differently when exposed to water. Therefore, properties built or retrofitted with flood-resistant materials (e.g. concrete or glass block walls, metal doors and waterproof membranes) along with elevated ground levels and flood-specific foundations have lower vulnerability to flooding when compared to those without these materials and features.
