cross section leveling procedure

FIELD PROCEDURE: DATA SHEET 3, 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 time.
