TUFLOW Viewer - Map Outputs - 3D to 2D Depth Averaged Cross-Sections
Tool Description
Extracts 3D to 2D depth averaged cross-section results along a polyline from the map outputs. Users can choose multiple methods and / or multiple instances of the same method with different parameters to plot at once. This tool expands on the cross-section plotting tool for 3D results as it lets users plot one or multiple 3D to 2D depth averaging methods at the same time (for example plot results from vertical layer 1, 2, 3.. etc). The standard cross-section plotting tool will plot only the current 3D to 2D depth averaging method being used to render the results.
For 2D depth averaged model results (i.e. TUFLOW Classsic / HPC) the 3D to 2D depth averaging methods will have no affect and produce identical result to each other.
To use the tool:
- Select the dropdown arrow next to the 3D to 2D Depth Averaged Cross Section icon
- Select (tick on) the 3D to 2D depth averaging method(s) - input appropriate parameters for the method and select the desired result type in the dropdown box
- Click off the drop down menu somewhere in a blank section of the TUFLOW Viewer toolbar
- Click the 3D to 2D Depth Averaged Cross Section icon so that it becomes indented and the cursor changes to a crosshair
- Left click in the QGIS map window to start drawing a line. Left click to add vertices to the polyline.
- Right click to finish drawing your line (note: line must contain at least 2 vertices and right clicking does not add a vertex)
To plot multiple instances of the same depth averaging method with different result types or different parameters, select Add Additional... in the dropdown menu. To uninclude additional methods from the plot, the methods can be unchecked, or can be removed completely by right clicking the method and selecting Remove Method.
