The Bristol Fall Column was constructed to analyse current transported sediments from 62mu to 8 mm. size. This is possible because a large sample is used (at least 50 gms.) which is sedimented in a full tube of 18 inches diameter. Other original features include a new sediment release mechanism. The importance of expressing results in terms of fall velocity is emphasized, and velocities determined for large samples in the new Column are compared with earlier single-sphere results.
