For RouteWetland command, there are two extra tabs called Hydroperiod and Inflow Mass Curve for Continuous project. In those two tabs, VO uses the results of one pre-development scenario to calculate difference from the other scenarios to the pre-development scenario. Therefore, before doing the scenario comparison, users should select one scenario from all the scenarios in the project as the Pre-Development Scenario. By default, the first scenario under the Drainage Network Scenarios in the Project Manager is the pre-development scenario. To assign any scenario as the pre-development scenario, select and right-click on the desired scenario under the Drainage Network Scenarios group in the Project Manager. In the opened context menu, click on Set as Pre-Development Scenario

Open Scenario Comparison and choose RouteWetland command. Click on Hydroperiod or Inflow Mass Curve to see the comparison. The grey lines in the graph of Hydroperiod are the the upper and lower boundaries of the confidence interval. You can change the Year to be compared and the desired Confidence Interval (%) from the drop-down list. Below the graph is the Statistics table summarizing the days when the Storage depth of the RouteWetland is out of the confidence interval for each scenario in the selected year.

For the Inflow Mass Curve, there are two options to plot the curve: Daily average flow and Instantaneous volume. The Daily average flow is the cumulation of daily average flow and the result is in the unit of flow. The Instantaneous volume is the cumulation of volume and the result is the unit of volume.
