Fluvial and pluvial flood maps for the central highlands of Vietnam and surrounding provinces, 2022

This dataset contains river (fluvial) and surface water (pluvial) flooding maps for the central highlands of Vietnam and surrounding provinces. Flood depth is estimated at 30m horizontal grid spacing for 10 return periods, ranging from the 1 in 5 year to the 1 in 1000 year return period flood. These maps are of relevance to planners and policy makers to estimate which areas of most at risk of flooding and can contribute towards policy such as the sustainable development goals.

Useful for

Use cases llm-inferred
Screen which settlements in the central highlands fall in high-depth fluvial or pluvial flood zones for regional planning or SDG-linked risk assessment · Provide regional flood-hazard context in an international development or due-diligence scoping study for Vietnam · Overlay 1 in 100 and 1 in 1000 year flood depths on project sites to brief planners and policy stakeholders
Audience llm-inferred
flood risk consultants · planners and policy analysts · hydrologists · GIS analysts

Limitations

Constraints llm-inferred
Geographic coverage is Vietnam's central highlands and surrounding provinces only; not applicable to UK projects · Single modelled year (2022 temporal extent) with no multi-year time series · Based on a global flood model with updates; validated against satellite imagery and household survey data, so local accuracy for engineering design is not established · Raster TIFF at 30 m; not suitable for site-scale detail below that grid spacing · Scripted downloads need a personal access token
