Flood and economics

The wider the gap between rich and poor the higher the flood mortality Nat. Sustainability

“When there is rain or snow, you can make more money”

The authors looked into economic inequalities like the Gini index associated with flood mortalities.

Establishment of flood damage function models: A case study in the Bago River Basin, Myanmar

The author collected questionnaire surveys and constructed a relationship between flood damage and water height.

Modelling the behaviour of corporations during the flood damage recovery process using multi-agent deep reinforcement learning

They used flood inundation modeling results overlaid with corporate behaviors during flooding and optimized their strategy using multi-agent modeling.

Indirect flood damage assessment

Direct flood cost is tangible cost, such as building submerged, fatalities, or cars.

Indirect cost, on the other hand, is invisible, such as wages, impairment of supply chain network, etc.

Flood Footprint Assessment: A Multiregional Case of 2009 Central European Floods

A literature review of flood footprint analysis including economic models used for disaster damage assessment.

The macroeconomic impacts of future river flooding in Europe ERL

The authors claim that the indirect cost during flooding could be as twice as direct cost.

This study presents a comprehensive flood risk analysis that explicitly includes regional economic interdependencies on a continental scale. They also analyzed the impacts of floods under climate change.

Indirect impacts are calculated by using a recursive dynamic multiregional supply and use model: the multi regional impact assessment (MRIA) model

For the direct damages, they used the depth-damage curve.
