Scope

Specifies methods for determining stage-fall-discharge relations for a stream reach where variable backwater occurs either intermittently or continuously. Two gauging stations, a base reference gauge and an auxiliary gauge are required for stage measurements. A number of discharge measurements are required in order to calibrate the rating to the accuracy required by this Technical Report.
