ISO 4363:2002规定了测量横截面平均悬浮泥沙质量浓度和平均粒径分布的常规和简化方法。常规方法用于稳定或缓慢变化流量期间的常规测量。简化方法主要用于泥沙测量，以观察泥沙输移的变化过程，可在困难条件下进行。建立了用常规方法和简化方法测量的横截面平均悬浮泥沙质量浓度和平均粒径分布之间的经验关系。ISO 4363:2002中规定的方法适用于水文站的悬浮泥沙测量。

ISO 4363:2002 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 ISO 4363:2002 are applicable to suspended sediment measurements at hydrological stations.
