Pneumatic Reduction of Salt Intrusion Through Locks
Theoretical considerations and field measurements show that a considerable reduction of intrusion of salt water through navigation locks can be obtained by releasing bubbles of air from perforated pipes placed on the bottom of the lock chamber. The bubbles of air create an upward flow of water that reduces the intrusion of salt water, provided that sufficient air is supplied. Design criteria are presented to determine the reduction of the intrusion of salt water as a function of air supply and other conditions (i.e., difference in density, depth of lock chamber, etc.). Experiments show that pneumatic barriers do not reduce navigability of ships passing through, and the pneumatic barriers are re-established shortly after a ship has passed. Salt water is diluted while penetrating through a pneumatic barrier.
