CREST AI Flood Dashboard

Describe a flood in plain language — “flood in Kerrville, Texas, July 2025” — or pick USGS gauges straight from the map, and the dashboard sets up and runs the CREST/EF5 hydrologic model live: 2-D streamflow animates over the map, hydrographs stream in as the model computes, and an AI assistant explains the event, reports skill scores, and can even calibrate the model parameters when the fit is poor.

The demo may take a moment to wake if it has been idle. A simulation with warm-up typically runs 2–4 minutes on the free hardware; repeat runs of the same basin are much faster thanks to state and result caching. If the embed doesn't load, open it in a new tab.

Short, silent clips from recorded sessions. They play while in view; use the controls to pause, scrub or go full screen.

Ask in plain language. “I’m interested in the floods in St. Louis in 2025” brings up a summary of the June 2025 event and the 77 USGS gauges nearby; zoom in and click pins, or draw a box, to choose the ones to simulate.

Simulate and replay. Four gauges on the River Des Peres, May–August 2025: the CREST/EF5 run completes, the time slider replays the event, streamflow lights up along the creek, and each gauge’s hydrograph and skill scores fill the panel.

AI calibration. When a gauge finishes with a weak fit, the assistant reports the NSE and offers to calibrate the model parameters itself — or hands over for manual adjustment.

Speed run. The domain is cut at upstream USGS gauges and their observations are injected as boundary conditions, so the model simulates a quarter of the basin about four times faster.

2-D inundation. When the nowcast flags a gauge at flood level, CREST-iMAP v2 simulates the basin in two dimensions — here the simulated water depth along the Youghiogheny River at Connellsville, PA (August 2026), with the trigger gauge’s routed nowcast against USGS observations.

Nowcast. No dates needed: the observed hydrograph at Frio River at Tilden, TX (July 2026) extends into the next 6 and 12 hours with the AI nowcast, and map colours flag gauges where trouble is predicted within six hours, refreshed hourly.
