Stream Networks for Three Eastern Sri Lanka River Basins

Eastern Sri Lanka's Mundeni Aru, Maduru Oya, and Miyangolla Ela river basins have mapped stream networks for hydrologic modelling. The data is provided as shapefiles and was supported by a Natural Environment Research Council grant.

Use Cases

• Conduct hydrologic flow simulations using the stream network geometry from the shapefiles.
• Analyze watershed connectivity and drainage patterns for the three specified river basins.
• Integrate stream network features into environmental models for flood risk or water resource planning.

Strengths

• Data is focused on three distinct river basins, providing targeted geographic coverage.
• Developed specifically for application in hydrologic modelling workflows.
• Managed and published by the Environmental Information Data Centre.

Limitations

• Dataset scope is limited to three basins in eastern Sri Lanka, not nationally representative.
• Lacks attribute columns or metadata detailing stream order, flow rates, or other hydrological properties.
• Recency of the underlying source data collection is unknown.
