The 1D-Hydraulic Cross Section coverage is used to identify the cross section stations in the hydraulic model, and can also be used to automatically cut a cross section from an underlying digital terrain model. This coverage is used in conjunction with the cross sections and digital terrain model in order to determine the thalweg position, or lowest point in the cross section (from the centerline arc), and the left and right bank points (from the bank arcs).
There are several attributes of a cross section feature arc, including the the cross-section itself and other parameters that define its topology in the model. These include a Cross Section ID (internally assigned), the Reach Name (inherited from the centerline arc it intersects), the Station (inherited from the centerline), and any specific model attributes.

A cross section profile is assigned automatically when cutting the cross sections, or can be assigned manually (imported from a file or entered directly) using the cross section editor.
See the help for editing cross sections to learn more about how cross sections are managed and edited.
