1、Designation:D567422Standard Guide forOperation of a Gaging Station1This standard is issued under the fixed designation D5674;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates
2、the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 The guide covers procedures used commonly for thesystematic collection of streamflow information.Continuousstreamflow information is necessary for understanding theamount
3、and variability of water for many uses,including watersupply,waste dilution,irrigation,hydropower,and reservoirdesign.1.2 The procedures described in this guide are used widelyby those responsible for the collection of streamflow data,forexample,the U.S.Geological Survey,Bureau of Reclamation,U.S.Ar
4、my Corps of Engineers,U.S.Department ofAgriculture,Water Survey Canada,and many state and pro-vincial agencies.The procedures are generally from internaldocuments of the preceding agencies,which have become thedefacto standards used in North America.1.3 It is the responsibility of the user of the gu
5、ide todetermine the acceptability of a specific device or procedure tomeet operational requirements.Compatibility between sensors,recorders,retrieval equipment,and operational systems isnecessary,and data requirements and environmental operatingconditions must be considered in equipment selection.1.
6、4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associate
7、d with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized
