Aqueduct Floods Methodology

Redactie openresearch.amsterdam

Flooding is among the most serious and dangerous of all global risks, causing loss of life and damage to property, livelihoods, and economies. Flooding is also likely to intensify in the coming decades due to climate change. Additionally, economic growth and urbanization are putting more and more assets and people into flood-prone areas. Despite these dangers, flood risks are often under- estimated and poorly managed due to the lack of data and actionable information, particularly in less-developed regions.

Aqueduct Floods is an online platform that measures riverine and coastal flood risks under both current base- line conditions and future projections in 2030, 2050, and 2080. In addition to providing hazard maps and assess- ing risks, Aqueduct Floods enables its users to conduct comprehensive cost-benefit analysis to evaluate the value of dike flood protection strategies.

Aqueduct Floods aims to empower disaster risk analysts and managers with quantitative information on flood risks and adaptation strategy costs, and to help inform policy and investment decision-making. This technical note explains in detail the framework, methodology, and data used in developing Aqueduct Floods to help users better interpret the risk information presented on the tool and understand the full strength and limitations of our data and methodology.
