Louisiana Watershed Initiative (LWI) Model Data
Geographic (land cover, land elevation, etc.), meteorologic (pluvial, wind, etc.), hydrologic (fluvial, tidal, etc.), hydrodynamic (water surface elevations, flow velocities), and built environment (structures, levees, floodgates, culverts) data used as inputs to and outputs from numerical modeling software for the prediction of flood risk in stochastic and probabilistic frameworks. This data was collected from open sources, such as from the National Oceanographic and Atmospheric Administration

Useful for
- Use cases llm-inferred
- Benchmarking US flood model input datasets (HEC-RAS/HEC-HMS) against UK-style flood risk study setups · Reviewing hydrodynamic outputs (water surface elevations, flow velocities) from a comparable US stochastic flood study · Built-environment exposure inputs (levees, culverts, floodgates) for a US flood risk comparison or training exercise
- Audience llm-inferred
- flood risk analysts · hydraulic modellers (HEC-RAS users) · hydrologists · GIS analysts
Limitations
- Constraints llm-inferred
- Geographic coverage is Louisiana, USA only; not applicable to UK sites · Updated yearly, so not suitable for real-time or live forecasting · Data is formatted for HEC-HMS/HEC-RAS modelling and may need conversion for other tools · Licence requires attribution to Louisiana Watershed Council · No time span or spatial resolution is stated in the docs, so suitability needs checking against the source files
