Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1991-01-01 Abstract The settling velocities of fine sediments can be determined using a sedimentation balance essentially consisting of a settling tube at the bottom of which the weight of the sediment deposited is measured as a function of time. The distribution of settling velocities then is calculated from an equation, which is known as Oden's formula. In this note the influence of random errors in the measured weight on the precision of the calculated distribution of settling velocities is analyzed. It is shown that the number of digitally sampled data values needed to calculate the distribution function increases with the ratio of time to sampling time interval, and that a compromise has be sought between precision and resolution.
