FIELD PROCEDURE: CROSS SECTION SURVEY
In this procedure, you will survey the stream channel cross section with a series of measurements along a permanentlyestablished 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 crosssection “footprint” over timeProfile leveling The process of determining the elevations of a series of points at measured intervals along a line such as the centerline of a proposed ditch or road or the centerline of a natural feature such as a stream bed Normally we will asWhat is the difference between profile leveling and cross
