Example cross section diagram.

Channel cross sections should be physically surveyed on site and not "cut" or extracted from the topography generated by mapping software. Streambed detail for monitoring purposes is not adequately represented in a cut or extracted cross section. Monitoring cross sections are most beneficial if located along the reconfigured channel in areas most sensitive to alteration by streamflow; for example, in areas that might scour or aggrade as bed material is transported, or in meander bends where lateral erosion could occur.
