Bank full width definition
Bank full width means the top surface width of the stream channel at a discharge corresponding to a water stage that occurs at a frequency of every one to two years (Q1.5 to Q2, i.e., there is a 50 to 66% chance of this high flow occurring in a given year). Bank full widths are measured from the crest of the right streambank to the crest of the left streambank for streams in equilibrium condition, from field scour and depo- sition indicators of bank full stage for incised channels, or, when field measurements are not available, as calculated from reference data such as the Vermont Hydraulic Ge- ometry Curves1.

Bank full width means the distance from bank-to-bank, perpendicular to the stream flow, at the point where the stream reaches high flows approximately every 1.5 to 2 years. Bank-full width is typically determined by a combination of vegetative and channel-form indicators.
