Louisiana Watershed Initiative Flood Risk Model Data

Geographic, meteorological, hydrologic, hydrodynamic, and built environment data used as inputs and outputs for numerical flood risk modeling in Louisiana. The data was collected from open sources like NOAA and USGS, formatted for use with the US Army Corps of Engineers' HEC-HMS and HEC-RAS software, and is made public by the State of Louisiana under a CC-BY-4.0 license. It supports stochastic and probabilistic flood prediction across a range of scenarios.

Use Cases

• Predicting flood risk under various scenarios based on hydrologic and hydrodynamic model outputs.
• Assessing the impact of land cover and elevation changes on flood patterns.
• Planning infrastructure resilience based on built environment data for structures, levees, and floodgates.
• Analyzing combined flood hazards from pluvial, fluvial, and tidal sources mentioned in the description.

Strengths

• Data is derived from authoritative open sources like NOAA and USGS.
• Modeling software (HEC-HMS, HEC-RAS) used is freely available from the US Army Corps of Engineers.
• Data is publicly released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file size, and last update date are unknown, which may limit suitability assessment.
