ISO 4365:2005规定了测定河流和运河中沉积物浓度、粒度分布和相对密度的方法。 以下给出了详细的分析方法: 通过蒸发和过滤测定悬浮泥沙浓度； 悬浮泥沙粒度分析； 推移质和推移质泥沙的测定； 确定沉积物的相对密度； 粒度分布特性的测定。

ISO 4365:2005 specifies methods for determining the concentration, particle-size distribution and relative density of sediment in streams and canals. The detailed methods of analysis are given for the following: determination of the suspended sediment concentration by evaporation and filtration; particle-size analysis of suspended sediment; determination of the bed-load and bed material sediment; determination of the relative density of sediment; determination of particle-size distribution characteristics.
