Liquid flow measurements in open channels — Stage-fall-discharge relations

95.99 Withdrawal of Standard Nov 22, 2001

General information

Current stage: 95.99 Effective date: Nov 22, 2001

Originator: ISO

Owner: ISO/TC 113/SC 1

Type: Technical Report

ICS: 17.120.20

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.
