Running Scenarios

A Scenario is the editable model configuration you build your inputs into: elevation, boundaries, inflows, any optional layers, and simulation settings such as duration and resolution. When you are ready to simulate, Hydrata builds the Scenario into a scenario package and starts a Run, a single compute attempt at that built Scenario, on cloud compute.

In this section

• Configuring Runs: set duration, resolution, and mesh options, then start a Run from the Scenarios panel.
• Selecting Inputs: choose which elevation, boundary, inflow, and optional inputs each Scenario references.

What happens during a Run

Each Run moves through a series of states, shown as a status pill in the Scenarios panel:

1. Building: Hydrata assembles your inputs into a scenario package
2. Queued: the Run is waiting for cloud compute
3. Computing: the ANUGA simulation is executing, with progress reported as a percentage
4. Processing: simulation outputs are converted into map layers
5. Complete: results are ready to view

If a Run ends in Error, fix the underlying issue and click Retry.

Note

A Run never changes your Scenario. To test a different configuration, edit the Scenario (or duplicate it) and start another Run.

After the Run completes

See the Results section to view depth, velocity, and stage layers on the map, or to export them for use in GIS software.
