Flood Risk

Nomadino flood-risk index on a 0-100 risk-point scale. Lower is better. The raw value combines WRI Aqueduct expected annual affected population, affected GDP and urban damage signals, INFORM river and coastal flood exposure, ThinkHazard river/coastal hazard levels, population and area context, coping-capacity/vulnerability signals and explicit replacement values for uncovered territories. Score equals 100 minus raw value.

How the Raw Value Is Calculated

The raw value is Nomadino flood risk in risk points from 0 to 100. 0 means very low structural flood exposure, while 100 means extreme exposure to river, urban or coastal flooding.

The calculation combines five components: 45% WRI Aqueduct for expected annual affected population, affected GDP and urban damage, 30% INFORM river and coastal flood exposure, 10% ThinkHazard hazard levels, 10% vulnerability and coping capacity, and 5% climate, storm and maintained flood context.

The main anchor is WRI Aqueduct Global Flood Risk. Country values are converted into expected annual burdens from multiple return periods. Absolute exposure and exposure relative to population are considered together so large countries and small densely populated risk areas are not distorted.

The INFORM Risk Index 2026 provides comparable values for river flood, coastal flood, vulnerability, institutional strength and infrastructure. Good administration and resilience can reduce the raw value in a bounded way, but they do not replace low physical flood exposure.

ThinkHazard acts as an independent hazard check for river and coastal flooding. This keeps countries visible where model values may understate regional or small-area flood hazards.

Minimum values apply to clearly documented high-risk settings such as Bangladesh, Viet Nam, Cambodia, Myanmar, Pakistan, South Sudan, the Netherlands, the Philippines and large exposed river deltas. Ceilings prevent very dry or barely exposed countries from being rated too high solely from older hazard classes.

Small or dependent territories use explicit Nomadino replacement values derived from administering state, island or coastal position, local hazard guidance, population density and plausible comparator countries.

The score is derived directly from the raw value: score = 100 minus raw value. A lower raw value therefore improves the ranking.
