Scenario Comparison can compare RouteChannel results in three erosion indices: Time of Exceedance, Cumulative Erosion Index and Cumulative Effective Work Index.

Click Scenario Comparison button in the Simulation toolbar.

In the opened Scenario Comparison window, uncheck the “Existing – Calibration”, which is used for model calibration, and check on the “Existing – long-term”, select RouteChannel in the Commands and click Erosion Indices tab. In the drop-down window of Type, select one index from the three erosion indices to be compared.

The figure below is the result of Time of Exceedance. Type a Critical Velocity 0.25 m/s and click Update. The Graph and the Statistics table will be updated.

The figure below is the result of Cumulative Erosion Index. Type a Critical Velocity 0.25 m/s and click Update. The Graph and the Statistics table will be updated.

The figure below is the result of Cumulative Effective Work Index. Type in Critical Shear Stress 1.5 Pa, Coefficient 1 and click Update. The Graph and the Statistics table will be updated.
