Description
Aqueduct Floods data measures riverine and coastal food risks under both current baseline conditions and future projections in 2030, 2050, and 2080. In addition to providing hazard maps and assessing risks, Aqueduct Floods helps 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 food risks and adaptation strategy costs, and to help inform policy and investment decision-making.
Google Earth Engine team recommendation:
This dataset can be used for:
- Larger scale regional analysis: what is the broad risk to the big area of the size of a US county level / large city?
- Preliminary assessments: when you need a quick, regional-scale "first look" at potential changes in river discharge without needing precise floodplain inundation maps.
- Relative changes: This looks at different climate scenarios so can be used for generalized changes in magnitude of impacts
This dataset should not be used for:
- Detailed flood inundation mapping: such as looking at properties specific risk
- Flat, lowland rivers: the simplification of the equations do not take into account backwater effects (water flowing backwards) which happens a lot in flood plains
- Analyzing hydraulic structures: it is not suitable for assessing the specific impact of structures like bridges, levees, or weirs that cause significant backwater effects
Please see the technical note from data provider for full details on the methods used and to understand if this data is right for your application.
