This repository accompanies the ASFPM webinar demonstration on how to build a HEC-RAS 2D hydraulic model using the NEER AI platform.
Follow the step-by-step instructions below to reproduce the demo, from creating
your account to generating flood depth rasters. All you need is the
project_boundary.geojson file included in this repository.
Using the NEER platform's AI agent, you'll create a HEC-RAS 2D model of the Blacksburg, VA study area and produce flood depth rasters for the 100-year flood event, with:
- No culvert burn
- No break lines
- 10-meter DEM terrain
- 100 ft × 100 ft computational mesh
-
A modern web browser
-
The
project_boundary.geojsonlink from this repository (you'll paste it directly into the agent chatbox — no download required):https://github.com/neeraip/ASFPM_Webinar/blob/main/project_boundary.geojson -
(Optional) A local install of HEC-RAS if you'd like to run the model on your own machine instead of on the platform
- Go to https://aip.neer.ai/.

- Return to https://aip.neer.ai/ and log in.
- Once logged in, make sure you are under your Personal account.
- Click New Project (or the + button).
- Give the project a name (for example,
ASFPM Webinar Demo) and create it.
Click on the project you just created to open its workspace. This is where the AI agent lives and where your data and models will appear.
-
Copy the project boundary GeoJSON link from this repository:
https://github.com/neeraip/ASFPM_Webinar/blob/main/project_boundary.geojson -
In the project workspace, paste the link into the agent chatbox and ask the agent to upload it, for example:
Upload this project boundary GeoJSON to the project: https://github.com/neeraip/ASFPM_Webinar/blob/main/project_boundary.geojson
With the boundary uploaded, ask the agent to build the model. Use a prompt like:
Create a HEC-RAS 2D model for the 100-year flood event, using a 10-meter DEM, with no culvert burn, no break lines, and a 100 ft by 100 ft mesh.
The agent will assemble terrain, boundary conditions, and the 2D flow area, then build the model to your specifications:
| Setting | Value |
|---|---|
| Model type | HEC-RAS 2D |
| Flood event | 100-year |
| Terrain (DEM) | 10-meter |
| Culvert burn | None |
| Break lines | None |
| Mesh cell size | 100 ft × 100 ft |
Once the model is generated, you have two options:
-
Run on the platform — ask the agent to run the simulation:
Run the model.
-
Run locally — download the generated HEC-RAS model from the platform and open/run it in your local HEC-RAS install.
After the simulation finishes, ask the agent to produce the flood depth rasters:
Upload the depth rasters.
The depth rasters visualize inundation extents and water depths across the study area for the 100-year event.
