ISO 4363:2002 明渠液体流量测量.悬浮沉淀物的特征测量法

This International Standard specifies conventional and simplified methods for the measurement of cross-sectional mean suspended sediment mass concentration and mean particle size distribution. The conventional method is used for routine measurements in periods of stable or slowly varied flow. The simplified method is mainly used for sediment measurements for the purpose of observing the variation process of sediment transport and can be performed under difficult conditions. Empirical relationships are established between the cross-sectional mean suspended sediment mass concentrations and mean particle size distributions measured by conventional and simplified methods. The methods specified in this International Standard are applicable to suspended sediment measurements at hydrological stations.

ISO 13550:2002 流速测定.利用建筑结构进行明渠流量测量.垂直下溢闸

This International Standard specifies methods for the determination of discharge in open channels in steady flow conditions using vertical underflow gates on a flat horizontal floor between vertical side walls under modular or non-modular conditions. NOTE Generally, gate controls are not designed with discharge determination as a primary function and this International Standard is intended to help the development of stage-discharge relations at existing gate structures, and to incorporate into new structures features which will provide good facilities for the establishment of stage-discharge relations. When a better accuracy of measurement (i.e. better than specified in 9.4) is required, the structure is to be calibrated with actual measurement of discharge using an appropriate method.

BS 3680-3Q:2002 明渠液体流量测量.河流流量测量中安全工作实施导则

This part of BS 3680 gives recommendations on the factors which should be included in any assessment of the risks associated with the various tasks involved in the operation and maintenance of sites used for the measurement of level and flow in open channels. Much of the work covered by this standard is, of necessity, carried out in close proximity to deep and/or fast-flowing water and frequently requires operating from floating vessels or entry into watercourses. Consideration is given to the potential additional hazards imposed by lone working, often in remote areas where assistance may not be readily available in the event of an emergency. Risk assessments undertaken using this standard procedure should not stand alone but be incorporated into the safe working practices operating locally at any time.

BS ISO 9123:2002 明渠水流测量.水位、落差和流量的关系

This International Standard specifies methods for determining stage-fall-discharge relationships 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 gauge height measurements. A number of discharge measurements are required in order to calibrate the rating to the accuracy required by this International Standard. The preparation of rating curves is not described in detail in this International Standard. NOTE For a more detailed description of preparing rating curves, see the methods described in ISO 1100-2

This International Standard specifies methods for determining stage-fall-discharge relationships 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 gauge height measurements. A number of discharge measurements ate re-quired in order to calibrate the rating to the accuracy required by this International Standard. The preparation of rating curves is not described in detail in this International Standard. NOTE For a more detailed description of preparing rating curves, see the methods described in ISO 1100-2
