Configuring Runs

A scenario brings together your inputs and simulation parameters into a runnable configuration.

Scenario settings

Setting Description Default
Duration Simulation time in seconds Required
Resolution Base mesh triangle size in metres Required
Simplify Mesh Use adaptive mesher for mesh generation false
Max RMSE Tolerance Error tolerance for adaptive mesher 1.0
Model Start Simulation start time (for time-varying inflows) 1970-01-01

How to run

  1. Open a project and navigate to the Scenarios panel
  2. Select or create a scenario
  3. Choose the inputs (elevation, boundary, inflow, etc.)
  4. Set duration and resolution
  5. Click Run

The simulation is queued and executed on Hydrata's compute infrastructure. Progress is reported as a percentage in the scenario status.

Outputs

After a successful run, the following outputs are generated:

Output Format Description
SWW file NetCDF Full time-series of depth, velocity, stage
Depth max GeoTIFF Maximum water depth at each point
Velocity max GeoTIFF Maximum flow velocity at each point
Depth-integrated velocity max GeoTIFF Maximum momentum at each point
Stage max GeoTIFF Maximum water surface elevation

Outputs are viewable in the map interface or downloadable for use in GIS software.
