Profile lines are another way of extracting linear data from a 2D flow area. Profile lines are frequently used to request the plot of terrain and computed water surface elevation down the centerline of a channel. Profile lines are also used to plot the time series output. The profile line should be drawn perpendicular to the flow direction left to right looking in the downstream direction for plotting time series data for the flow crossing the line.
In GeoHECRAS, the user can create 2D profile lines on the Map View using the Assign Profile Lines and Draw Profile Lines commands. Both commands have similar functionality but somewhat distinct workflows.
Note that these commands should only be used after a successful HEC-RAS analysis run.
The Assign Profile Lines command allows the user to define a profile line from previously imported CAD or GIS data.
The Draw Profile Lines command allows the user to interactively draw 2D profile lines on the Map View.
The software allows the user to request various types of output such as water surface elevation and terrain profile, velocity profile, and flow depth profile along the 2D profile lines.
From the Results ribbon menu, expand the Profile Plots dropdown combo box and select the Profile Line Plot command.
The Profile Line Plot dialog box will be displayed. Alternatively, the user can double-click on the profile line in the Map View to display this dialog box and view output results underneath that profile line.
Notice that while viewing the water surface elevation profile, the terrain profile is included in the plot for reference.
The Scenarios dropdown combo box allows the user to view output results from different scenarios. To learn more about working with multiple scenarios, refer to this article in our knowledge base.
The Profiles dropdown combo box allows the user to view output results for multiple profiles at the same time. By default, the software selects the Max option.
Using the Profile Lines dropdown combo box, the user can select the profile line to display output results underneath it. The plot can display output results for multiple profile lines at the same time.
The user can request various types of output (Velocity, Flood Depth, Time Series-Flow etc.) along the selected profile line(s) from the Plot type dropdown combo box.
The GeoHECRAS software also allows the user to create professional printouts of profile line plots, save them as image file as well as export them to PDF file. To print or export the results of a profile line plot to a different format, right-click anywhere on the plot and select the Export to PDF, Save as Image or Print option.
The user can also configure the display properties of profile lines plots and their IDs on the Map View. To learn more about this feature, refer to this article in our knowledge base.
