Abstract
A system consisted of a personal computer and a digital video camera was developed for measuring a distribution of sand grain size. A sample of beach sand which had a median diameter of 0.28mm was prepared hi order to check this system. The distribution of sand grain size measured by this system was agree well with the data from the sieve analysis. Major advantages are that this system requires smaller amount of sand sample (2000-2500 grains) and less time for analysis than these for sieve analysis.
