A full scale experiment with a deep loaded push-tow barge combination was carried out in the Juliana Canal to determine the stability of a canal bed against future ship-induced loads. The resulting under keel currents and the subsequent bed erosion were monitored and analyzed. Clearly, the results showed that in the future the canal bed will be instable. The observed bed lowering could be estimated with a time/dependent scour prediction formula. The results of the observed flow velocities under the ship´s keel were comparable with measured flow velocities in small-scale experiments
