FLASH

Flooded Locations and Simulated Hydrographs Project

The Flooded Locations and Simulated Hydrographs (FLASH) is a flash flood prediction model intended to improve the accuracy, timing and spatial resolution of warning systems for flash floods. FLASH produces flash flood forecasts at one kilometer resolution at near-real time.

Model Information
For more information about this model, go to blog.nssl.noaa.gov
Spatial Resolution
Model uses a 1-km grid resolution.
Temporal Resolution
Model uses 5 minute time steps.
Outputs
Outputs include probabilistic flood risk and storm return periods. Outputs are determined through comparison with historical storms from the NEXRAD database, which includes stream flow, precipitation, return period, and percent exceedance data up to 12 hours in the future.
Intended User
practitioner, decision maker
Model Type
risk communication
Inclusion of Climate Change
Climate data are not incorporated. The model generates short term predictions and return periods are based on hindcasts.
