Cross sections are necessary for measurement of earthwork volumes in roadway construction. They are profile views of the ground, perpendicular ... scale, making the shape of the ground easily visible. This procedure is especially helpful when plotting profile grades at intersections, railroad crossings, bridge approaches, wedge levels, etc.
In this procedure, you will survey the stream channel cross section with a series of measurements along a permanently-established line. The data you gather will be entered into a computer database that can generate a graph of the cross section and calculate the degree of change in the cross-section "footprint" over time.

Mar 09, 2017· 2 In profile leveling, you determine the elevations of a series of points lengthwise along a highway (a road). In cross-section leveling, you determine the elevations of points on a succession of lines running at right angles to the lengthwise line of the highway.
Mechanical cross sectioning, although not as accurate or easy to perform as focused ion beam cross sectioning, is relatively inexpensive to perform. A good cross sectioning wheel and the necessary supplies cost less than $10k. A bad cross section is worse than no cross section at all, since the process is destructive.

What Is Profile Leveling? Profile leveling can be defined as determining the elevations of points in a series at measured intervals along a line, such as the centerline of a proposed road. Profile leveling is an extension of differential leveling, and a closure check is required if the line runs between bench marks.
