WMS:Linking Models

The final step before running a stochastic simulation is to link any required models. In particular you have to link how the hydrologic modeling results are used as boundary conditions for the HEC-RAS hydraulic model. When you choose the Run Stochastic Model option the Model Steering Dialog appears. For the hydrologic model you are using (HEC-1) you must assign the appropriate hydrograph (basin or outlet) to the river reach and section in the hydraulic model.

The option to Assign Hydrographs Automatically can be used providing a drainage coverage and centerline coverage are being used to set up the hydrologic and hydraulic models.

After identifying the hydrograph and the river, reach, and cross section station select the Assign Hydrograph BC button to link the models for this point. Continue until all of the appropriate model locations are linked.

When selecting OK your model simulation will run.
