Median grain size is often used as a representing size in the calculation of sediment transport. But, it may not meet the physical mean of sediment transport completely. Comparison is made on the median grain size and the grain size weighting by percentage retained. Two grain sizes are calculated on the basis of the numerous grain size distributions of bed material collected from offshore western Taiwan. It is shown that the grain size weighting by percentage retained is better than the median grain size to represent the various grain sizes of bed material. In addition, the percentage finer of the grain sizes that takes into consideration of the the weighting of the percentage retained is introduced to investigate the influences of grain sizes of bed material on water depth.
