Once you have added the river reaches to your model, you can add the associated cross-sections. Again, we add these in sequential order starting at the downstream end working upstream. Sections should be added as looking upstream, at locations where there are any significant changes in the section shape, geometry or channel slope.<\/p>\n

Also, Channel Studio automatically prepares a coordinate-based Plan map of your Model. If you want to produce a Plan Map that exactly follows the curvature of your Reach layout, please make sure your total cross-section widths do not increase or decrease by more than 10 percent from adjacent cross-sections. Otherwise the Plan Map will be constructed of straight line segments, which is okay. See Plan Drawings<\/a> for additional information.<\/p>\n

How to Add Cross-Sections<\/h2>\n

1. From the Model tab, click on the Cross-Section button on the side tool bar.<\/p>\n

\"\"<\/p>\n

2. Move the mouse cursor over to the desired river reach location. Channel studio will automatically draw a section line perpendicular to the reach segment. When you have located the section at the desired river station, click your mouse button. A new section will be added and numbered accordingly. Repeat this process for additional upstream sections. Remember, the first Reach segment must contain at least one Section.<\/p>\n

Note: You will have the ability afterwards to directly edit the Section’s exact station location on the Input Grid.<\/p>\n

3. Click the Ok\/Select button on the side tool bar or press the [Esc] key when done.<\/p>\n

A typical model layout with cross-sections looks like this:<\/p>\n

Notice how the cross-sections lines span the entire floodplain.<\/em><\/p>\n
