Standard Test Method for Open-Channel Flow Measurement of Water Indirectly by Slope-Area Method
 N D5130

Annotation

This test method covers the computation of discharge (the volume rate of flow) of water in open channels or streams using representative cross-sectional characteristics, the watersurface slope, and coefficient of channel roughness as input to gradually-varied flow computations.2,3

This test method produces an indirect measurement of the maximum discharge for one flow event, usually a specific flood. The computed discharge may be used to help define the high-water segment of a stage-discharge relation.

The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2 This test method is similar to methods developed by the U.S. Geological Survey and described in Refs (1-3).3

3 The boldface numbers in parentheses refer to a list of references at the end of this standard.
