Transforming existing HEC-HMS models into real-time flood intelligence

Predict.
Prepare.
Protect.

FloodGeo takes the HEC-HMS model your agency already owns and runs it in the cloud against live NOAA rainfall and the National Water Model — then warns the people on call before the water arrives.

The shift

Everything a flood model normally needs, removed.

Just actionable flood information, when it matters most.

desktop HEC-HMS software

The model runs in the cloud, on a schedule.

specialized modeling expertise

Reading a forecast is the only skill required.

waiting for someone to run it

Results are already there when the rain starts.

Layer · Basin

Your watershed, already running.

The same basin, reaches and computation points from your HEC-HMS model, published as a live map. Advance the rainfall, switch layers off, open any junction.

National Water Model streamflow for every reach, with the ensemble spread when you need the uncertainty and the thresholds that matter for that location drawn straight across the plot.

Set the line. Choose who gets woken up.

Arm a threshold and run the forecast against it. If the water crosses, the message goes out with the reach, the tier and the time. If it does not, nothing is sent.

Who uses FloodGeo

Built for the people who have to decide.

Nine kinds of organization, one shared problem: the model exists, but not where the decision gets made.

Emergency Management Agencies

Decide when to close roads and open shelters

Cities & Counties

Watch every basin in the jurisdiction at once

River Authorities

Track reach-by-reach discharge through an event

Flood Control Districts

Compare forecast peaks against design capacity

Consulting Engineers

Put an existing HEC-HMS deliverable to work

Water Resource Managers

Follow runoff from rainfall to outlet

Transportation Agencies

Get warned before a low-water crossing goes under

Utilities

Protect lift stations and substations in the floodplain

Universities & Researchers

Replay historical storms against the model

Key capabilities

What the platform does.

Real-time flood forecasting

Your model runs against live rainfall as it falls, and republishes results without anyone opening a desktop app.

Forecast flood risk

See predicted discharge at every junction, ranked against the thresholds that matter for that location.

Historical storm analysis

Re-run any past storm through the current model to test thresholds before you rely on them.

Interactive web mapping

Pan the basin, toggle rainfall, and open any junction. No GIS license, no plugin, no install.

Automated flood alerts

Text and email go out the moment a forecast crosses a threshold you defined, to the recipients you chose.

Cloud-based platform

One URL for the whole agency. Access is a login, not a workstation with the right software on it.
