Yemen Waterways from OpenStreetMap for Flood Risk Analysis

OpenStreetMap exports provide water features across Yemen, including rivers, streams, canals, lakes, ponds, and water bodies. The data is compiled by the Humanitarian OpenStreetMap Team (HOT) and was last updated on 2026-05-15. It is useful for flood-risk modelling, watershed analysis, and environmental basemap context.

Use Cases

• Flood-risk modelling based on the mapped waterway network.
• Watershed analysis based on the distribution of rivers, streams, and lakes.
• Creating an environmental basemap context based on natural water features.

Strengths

• Data is available in multiple geospatial formats including GEOPACKAGE, KML, SHP, and GEOJSON.
• Derived from OpenStreetMap, a free, collaborative world map built by volunteers.
• Covers specific water-related OSM tags: `waterway`, `water`, and `natural=water`.

Limitations

• Completeness varies by region; urban areas are usually well-mapped, remote areas may be incomplete.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
