9.2.3 Hydrograph Plot

The Hydrograph Plot feature can be used to view hydrographs graphically without the need for a third-party application. This feature allows users to quickly view their hydrographs, compare them, and make qualitative assessments about their model.

VO provides three (3) options to plot hydrographs for single-event simulation:

• Hydrograph tool – Plot hydrograph with rainfall data. It can be used to check the hydrograph responses and compare the hydrographs from different objects in the same scenario;
• Cross Scenario Plot tool – Plot hydrographs from different scenarios (e.g. existing and proposed). It can be used to compare hydrographs of the same command from different scenarios;
• Plot Calibration tool – Plot simulated and observed hydrograph. The comparison is helpful for model calibration.
